C + +: Int and string convert each other

If the interchange between int and string is often used in a C + + program, a personal suggestion can be written as a function that is called directly at the next use.

#include <iostream> #include <string> #include <sstream>using namespace std; int-> stringstring inttostring (int num) {stringstream str0;string str;str0 <<num;str0>>str;return str ;} int main () {string str1 =inttostring (321);cout<< "str1=" <<str1<<endl;    string-> int    String str2 = "456";    int m = atoi (Str2.c_str ());cout<< "m=" <<m<<endl;return 0;}
