Stoi() Cpp Code Example

Example 1: convert stirng to int c++

int thing = std::stoi(string);

Example 2: stoi c++

// stoi example #include <iostream>   // std::cout #include <string>     // std::string, std::stoi  int main () {   std::string str_dec = "2001, A Space Odyssey";   std::string str_hex = "40c3";   std::string str_bin = "-10010110001";   std::string str_auto = "0x7f";    std::string::size_type sz;   // alias of size_t    int i_dec = std::stoi (str_dec,&sz);   int i_hex = std::stoi (str_hex,nullptr,16);   int i_bin = std::stoi (str_bin,nullptr,2);   int i_auto = std::stoi (str_auto,nullptr,0);    std::cout << str_dec << ": " << i_dec << " and [" << str_dec.substr(sz) << "]\n";   std::cout << str_hex << ": " << i_hex << '\n';   std::cout << str_bin << ": " << i_bin << '\n';   std::cout << str_auto << ": " << i_auto << '\n';    return 0; }
