Converting between int and std::string in C++
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;
}
