How to convert an int to string in C++?
You can use the itoa function from C to convert an int to string.
example
#include<iostream>
int main() {
int a = 10;
char *intStr = itoa(a);
string str = string(intStr);
cout << str;
}Output
This will give the output −
10
This will convert the integer to a string. In C++11, a new method, to_string was added that can be used for the same purpose. You can use it as follows −
Example
#include<iostream>
using namespace std;
int main() {
int a = 10;
string str = to_string(a);
cout << str;
}Output
This will give the output −
10
