This function converts any hex string like 55
to its equivalent decimal value:
#include <sstream> #include <int> unsigned int hexToDec(const std::string& str) { unsigned int ret; std::stringstream ss; ss << std::hex << str; ss >> ret; return ret; }
e.g.
hexToDec("55"); // returns 85
Note that while the code is somewhat concise, it might be neither the most performant nor the most concise option especially for developers that don’t really know std::stringstream
.
