invalid operands to binary *
I think you want to read the number of pixels from stdin: int n; scanf("%d", &n); and then allocate memory for that many pixels: unsigned char * buffer = (unsigned char *) malloc (sizeof(pixel) * n );

Invalid operands of type 'double' and 'int' to binary 'operator%'
Your static_cast isn't doing anything. What you should be doing is: if(static_cast<int>(maxTotal) % 2 == 1) Variables in C++ cannot change types. Static cast returns the casted value it does not change the input variable's type, so you have to use it directly or assign it. int iMaxTotal = static_cast<int>(maxTotal); if(iMaxTotal % 2 == 1) addCalc = minTotal; else addCalc = 0; This would work too.

C++11: invalid operands to binary expression ostream and ostringstream
It may compile in C++03, but it doesn't make one bit of sense. C++11 just used a new feature to make the code that makes no sense, not compile in the first place. See, std::ostringstream (and all other stream classes) used to have an implicit conversion to void*. What this returned wasn't a proper pointer, though; it was just either null if the stream was in an invalid state, or not null if it was valid. That's what allowed you to write e.g. std::ofstream ofs("filename"); if (ofs) ... However, the conversion to void* was problematic, because you do other stupid stuff with a void*. Even before C++11, the safe-bool idiom was discovered that would have been better. But for C++11, explicit conversions were added, which were a lot better. So for C++11, the conversion to void* was replaced b

invalid operands to binary expression ('int_node' and const 'int_node')
My compiler says "1>main.cpp(28): error C2676: binary '!=' : 'int_node' does not define this operator or a conversion to a type acceptable to the predefined operator" which is true. We could define != in terms of == e.g. for your missing int_node bool operator == (const int_node &i) const {return val == i.val;} bool operator != (const int_node &i) const {return !(*this==i);} You need to define the operators - should they check the node as well? BTW, do you intend to return first no matter what? while (first != last && *first != value) { ++first; return first; // ^^^^^ // ||||| }

C++ overloading > for priority_queue (min heap): yields "invalid operands to binary expression ('const Node' and 'const Node')" on push() for heap
You must mark the operator as const: bool operator> (const Node &rhs) const { return d > rhs.d; } EDIT If you don't want to overload operators, you can provide your own comparator to the queue: struct Comparator { bool operator() (const Node &lhs, const Node &rhs) const { return lhs.d > rhs.d; } }; void foo(const vector<Node> &list) { priority_queue<Node, vector<Node>, Comparator> q; q.push(list[0]); } EDIT 2 Here's how you could use a custom map: struct Comparator { typedef std::map<Node, float> Map; explicit Comparator(const Map &map) : map(&map) {} bool operator() (const Node &lhs, const Node &rhs) const { return map->find(lhs)->second > map->find(rhs)->second; }

C: invalid operands to binary > (have ‘float’ and ‘float (*)(float **, long int, long int, short int *)’)
It's a typo: use if((ArrayIn[i][j]>maxvalue)==1){ ^ !!! and maxvalue = ArrayIn[i][j]; ^ !!! You have declared a variable float maxvalue (non-capital 'v'), and a function maxValue(...) (capital 'v') - so the compiler tries to use the function as second operand of the comparison when you use maxValue there. Keep in mind that C is case significant - so maxvalue and maxValue are different symbols, but they need to be used properly. Ideally, try to avoid such issues by choosing better names - for example, use getMaxValue() or calculateMaxValue() for the function name. Besides that, if((ArrayIn[i][j]>maxvalue)==1) is unnecessarily complex - simply use if(ArrayIn[i][j] > maxvalue)

Why is my iOS app's binary invalid when uploading a new version?
Could be a lot of reasons. The common one these days is the UDID deprecation. Are you doing anything related to UDID in your app? Just to make sure, go to your project library within the terminal and type: $ find . | grep -v .svn | grep ".a" | grep -v ".app" | xargs grep uniqueIdentifier If you're getting a result, that's your problem. Also check your email, there's a mail from apple assigned to that Invalid Binary notice with more details.

Invalid Binary File after uploading on ITunesConnect
App icon file must be named Icon.png. It appears that your binary includes a file with incorrect name or a space in between. Check the app icon file's name. Also check your XCode project for any stray file with name Icon .png. Sometimes due to version control softwares there can be some hidden files backup with strange name. Check for hidden files/folders with name Icon . in your XCode project. Any such files getting included in your XCode project will get added in the app binary resources.

Invalid Image - For iOS applications, icons included in the binary submission must be in the PNG format
We update our app a couple days ago. And we receive the same email, i did a couple of google searches. I Found out that email could be related to ios7 release. since the old ios6 icons are 114x114 for iphone and 144x144 for ipad. Now apple is basically asking us to change the size of our icons to 120x120 for iphone and 152x152 for ipad. I could be wrong, but i am pretty convinced that's something related to ios7 which maybe released in a couple of weeks. Hope this will help ...

Put operands first in getopt()
If you use the GNU C library's implementation of getopt, then it will work like all GNU utilities do, because almost all of them use it. In particular, (quoting from man 3 getopt): By default, getopt() permutes the contents of argv as it scans, so that eventually all the nonoptions are at the end. That's not quite the same as gcc. gcc cares about the relative order of optional and positional arguments. (For example, it makes a difference where -l goes in the command line.) To do that, you'll have to tell GNU getopt to not permute the arguments. Then, every time getopt reports that it's done, optind will have the index of the next positional argument (if any). You can then use that argument, increment optind, and continue using getopt, which will continue at the next argument.

when should i use PTR with indirect operands ?
Perhaps you refer to this mnemonic syntax (e.g. objdump -Mintel): add DWORD PTR [eax],0x5 The point here is that [eax] is just a location in memory, but it doesn't carry size information. So we don't know whether to add 5 to a byte, a word, a dword or a qword. It would be clear if we used the annotated opcode names (addb, addw, addl, addq), but this particular dialect of assember chooses instead to annotate the memory operand. In this case, it says, "treat eax is a pointer to a dword". By contrast, register operands need no such annotation, since the register name implies its size: add al,0x5 ; addb add ax,0x5 ; addw add eax,0x5 ; addl add rax,0x5 ; addq

C# Bitwise Operands Vs PHP
C# uses zero-based arrays but PHP's unpack(..) uses a 1-based array. You could either change $strHex = unpack("C*",$strReq); to $strHex = array_merge(unpack("C*",$strReq)); to make your PHP array zero-based, or simply set $k to an initial value of 1. After testing either solution the PHP results are the same as the C# output.

Java operands priority x++ and *,+
Operands are evaluated left to right. So your code is equivalent to: int test1 = x * 4 + x; //2 * 4 + 2 x = x + 1; int temp = y; y = y + 1; // y = 3 int test2 = temp + y * 4; //2 + 3 * 4

Evaluation of operands in assignment operation
It is exactly the same situation. The only difference is that in your second example, a, b, and c have no side effects. No matter which way your compiler's implementation decides to evaluate them, the result will still be the same since none of the evaluations does anything.

Operator '!=' cannot be applied to operands of type 'bool?' and 'int'
I suspect you just want: && !c.CHILDAPPLIES && !c.SPOUSEAPPLIES ... although you should consider whether you want this to match rows where the columns are NULL rather than true or false. If the above doesn't compile (which it may not) you can effectively provide the "default" value with the null-coalescing operator: && !(c.CHILDAPPLIES ?? true) && !(c.SPOUSEAPPLIES ?? true) or && !(c.CHILDAPPLIES ?? false) && !(c.SPOUSEAPPLIES ?? false) The problem is that in the LINQ mapping, they're not "0 or 1" values - they're "true or false" values (or null) - so you can't compare them with integers.

Addition efficiency proportional to size of operands?
In practice, there's no (or completely negligible) difference between adding different integers that fit in the processor words as that should always be a fixed-time operation. In theory, the complexity for adding two unsigned integers should be O(log(n)) where n is the bigger of the two. As such, you need to go pretty high before mere additions become a problem. As for where exactly to draw the line between simple and complex algorithms for computing numbers, I don't have an exact answer. However, the GMP library comes to mind. From what I understand, they've carefully chosen their algorithms and under what circumstances to use each in terms of performance. You may want to look into what they did.

When making binary masks for working and isolating bits and bytes, what's the fastest way to convert from Binary to Hex?
Each set of four bits corresponds to one hex 'digit'. Learn those, then just start converting blocks of four from right to left. (If you're converting a bit string that's not a multiple of four bits, then just add zeros to the left end until it is for the last conversion.) 0000 : 0x0 0001 : 0x1 0010 : 0x2 0011 : 0x3 0100 : 0x4 0101 : 0x5 0110 : 0x6 0111 : 0x7 1000 : 0x8 1001 : 0x9 1010 : 0xA 1011 : 0xB 1100 : 0xC 1101 : 0xD 1110 : 0xE 1111 : 0xF

Why do Ruby and JavaScript bitwise operators yield different results with the same operands?
For the Ruby version, it looks like 256 >> -4 is equivalent to 256 << 4, so the negative operand essentially just switches the direction of the shift. From looking at the ECMAScript specification for the right-shift operator, in JavaScript, the operand is converted to an unsigned 32-bit integer before the shift, so the -4 becomes 4294967292. After this conversion the 5 least-significant bits are used for the shift, in other words we would end up shifting by 4294967292 & 0x1f bits (which comes out to 28). It probably shouldn't surprise you at all to see that 256 >> 28 gives 0. For convenience, here is the text from the spec (steps 6 and 7 are most relevant to your confusion here): The Signed Right Shift Operator ( >> ) Performs a sign-filling bitwise

Implementing a binary insertion sort using binary search in Java
How an insertion sort works is, it creates a new empty array B and, for each element in the unsorted array A, it binary searches into the section of B that has been built so far (From left to right), shifts all elements to the right of the location in B it choose one right and inserts the element in. So you are building up an at-all-times sorted array in B until it is the full size of B and contains everything in A. Two things: One, the binary search should be able to take an int startOfArray and an int endOfArray, and it will only binary search between those two points. This allows you to make it consider only the part of array B that is actually the sorted array. Two, before inserting, you must move all elements one to the right before inserting into the gap you've made.

Yes. This behavior is commonly used in idiomatic perl. Consider: open FILE, ">$fname" or die $!; If there is no error opening the file (open returns true), the die statement is not executed. This is not special treatment of the die routine; it is just the way perl handles logic evaluation.
