问题 Scar Divi Float or Double to Int. How I pass a Float/Double to Integer? Here's the code. I'm trying to Find the bitmap and click on the center, the problem is when I try to divide the x or y to find the img center. program FindBitmap; label main; var Bmp: TSCARBitmap; x, y: Integer; temp1, temp2: String; begin ClearDebug; Bmp := TSCARBitmap.Create('deNqtzGkKglAUhuE2Ea2pwXm8atpAFCIVRdEKi' + 'qJCkBBpAeVQa+zCBRGH++cEz6/Dd95Oq92ajoZwE8eCG9sm3GhowDkWgrNNHc4' + 'yNDgTqbnz6fjNMrr49XIXs

问题 Is it possible to mmap file full of integeres as integer array? I mean sth like this (which doesn't work) given file tmp.in 1 2 15 1258 and similar code to this int fd; if ((fd = open("tmp.in", O_RDWR, 0666)) == -1) { err(1, "open"); } size_t size = 4 * sizeof(int); int * map = (int *) mmap(NULL, size, PROT_READ | PROT_WRITE, MAP_SHARED, fd, 0); I'd like to be able call printf("%d\n", map[2]+1); with expected result 16 I found char mapping using sscanf to parse integers, but I need to have

问题 This question already has answers here : Closed 7 years ago . Possible Duplicate: implement division with bit wise operator I recently got into more depth by bitwise functions, and started to implement basic arithmetic functions with bitwise operators. So far I have gotten (+, -, *) . However I'm not really sure how to approach division. I know that I could somehow use multiplication instead, but not sure how to approach this using that method either. So how would I implement division using

问题 Is INT_MAX different between a 32-bit and 64-bit environment? It seems like it would be the case, though I've heard people say that the 64-bit environment just uses the 32-bit environment's INT_MAX. 回答1: It depends on the system. On Intel Linux they are the same. check limits.h 回答2: Your question is perhaps too generic, but on typical 64bit enviroment (x86-64) int is defacto the same size as on 386 (keeping in mind that this also depends on OS, not just architecture). C standard only limits

问题 I have this input: Input: 2015 And I want to scanf him like this: scanf("%1d", &arr); But this is definitely wrong. What can I do? I want to receive the input integer by integer like '2','0','1','5' , and not like "2015". 回答1: Just read each character individually, and convert the individual char s to integers. #include <stdio.h> int main(int argc, char* argv[]) { size_t len, i; char buff[64]; fgets(buff, sizeof(buff), stdin); for(i = 0, len = strlen(buff); i < len; ++i) { int curr = buff[i]

问题 I'm currently implement left shift using int[] arrays in php and need to get back the decimal after operation. So I have written the following snippet to attempt conversion of binary array to decimal. function bin2dec($bin) { $length = count($bin) - 1; $sum = 0; //convert using doubling for($i = 0; $i < $length; $i++) { //use string_add if doubling bigger than int32 if($i >= 16) { $double = $this->string_add("$sum", "$sum"); $cr = $bin[$i]; if($cr == 0) { $sum = $this->string_add($sum,

问题 In my code, I am using float to do currency calculation but the rounding has yielded undesired results so I am trying to convert it all to int. With as little change to the infrastructure as possible, in my init functions, I did this: -(id)initWithPrice:(float)p; { [self setPrice:(int)(p*100)]; } I multiply by 100 b/c in the main section, the values are given as .xx to 2 decimals. I abnormally I notice is that for float 1.18, the int rounds it to 117. Does anyone know it does that? The float

问题 I'm investigating why scan.nextInt() consumes the previous integer from the second iteration onwards. Can anyone make sense of what's going on and also explain what "The scanner does not advance past any input" means exactly? Please ignore the infinite loop. It's only for testing purposes. Example: Enter new data: 0 0 data entered Enter data again: 1 executed Enter new data: 1 <- this value is automatically entered (taken from previous input) data entered Enter data again: while(true) {
