RE: [Dev-C++] Integer to std::string?

[Ioannis V. <no...@ya...>]

I do not know string's member functions yet, but i know C well and you
can use sprintf() to convert a number to a C string, so:

#include <cstdio>
#include <iostream>
#include <string>

int main()
{
 using namespace std;

 char array[100];
 
 sprintf(array, "This is a string with numbers, %d is integer, %f is
float", 2, 5.5);

 string s=array;
 
 cout<<s<<endl;
}
