how to convert from int to char*?

by

  • In C++17, use std::to_chars as:

    std::array<char, 10> str;
std::to_chars(str.data(), str.data() + str.size(), 42);

  • In C++11, use std::to_string as:

    std::string s = std::to_string(number);
char const *pchar = s.c_str();  //use char const* as target type

  • And in C++03, what you’re doing is just fine, except use const as:

    char const* pchar = temp_str.c_str(); //dont use cast
