C/C++遇到的问题及分析

总结使用C/C++遇到的问题及分析：

1. Run-Time Check Failure #2 - Stack around the variable 'hex' was corrupted.

代码：

char bin[64] = "\x10\x5A\xFF";char hex[64] = {0};Bin2Hex(hex, sizeof(hex), bin, 3);

DWORD WINAPI Bin2Hex(LPSTR pHex, DWORD dwBufLen, LPCSTR pBin, DWORD dwLen){DWORD dwNowLen = 0;if(NULL == pHex || NULL == pBin){return 0;}for(DWORD i = 0; i < dwLen; i++){dwNowLen += 2;sprintf_s(pHex + i * 2, dwBufLen, "%02X", (BYTE) *(pBin + i));}return dwNowLen;}

调用sprintf_s函数，缓冲区大小不匹配所导致，改为：

sprintf_s(pHex + i * 2, dwBufLen - i * 2, "%02X", (BYTE) *(pBin + i));
