我有以下PHP代码:
$tagId = 1; // the original value of tag
$tagIdAsHex = sprintf("%02X", $tagId); // the tag value in hex format
$tagAsHexBytes = pack('H*', $tagIdAsHex); // the packed hex value of tag packed into string as a conversion
我如何把它翻译成C++呢?
byte tagId = 1;
auto hexedTag =
我在github上看到了下面的代码。
/**
* Filters an array of objects with multiple criteria.
*
* @param {Array} array: the array to filter
* @param {Object} filters: an object with the filter criteria as the property names
* @return {Array}
*/
function multiFilter(array, filters) {
const filterKeys = Obj
我执行了以下C++代码,得到了“不一样?奇怪……”的答案。原来我希望能得到“当然,他们是一样的!”我用的是Dev-C++ 5.11。
#include <iostream>
using namespace std;
int main() {
float p;
p = 0.3;
if ((p-0.3)==0)
cout << "Of course, they are the same !!!\n";
else
cout << "Not the same? Weird...
