By admin | November 20, 2010
#include <iostream> #include <sstream> #include <cstdlib> using namespace std; int main() { // convert int to string int some_int = 52; stringstream ss; ss << some_int; string result_s; ss >> result_s; // result_s = 52 cout << result_s << endl; // convert string to int string some_string = "1234"; int result_i = atoi(some_string.c_str()); // result_i = 1234 cout << result_i << endl; }
