WebApr 7, 2024 · For example, to convert a string to an integer, we have five functions: atoi, stoi, strtol, sscanf and from_chars. This library makes use of C++17s from_chars () for string -to-number conversion and to_chars () / to_string () for base 10 number to char array/ std::string conversions. In the case of base 8 and 16, it uses sprintf ()/sprintf_s ().
