Thread: Combining variables into one string

Hi, I'm having a pretty simple (I hope) problem, but I just can't figure it out.

I need to combine several variables into one string. For example if I have

Code:

string name = "Joe";
int age = 55;

string description;

I want to arrange it so that description = "Joe: 55".

The best solutions I could come up with are

Code:

description = name ": " age;
and
description = name + ": " + age;

and neither of those work at all. What should I do?

Use stringstreams.

Code:

#include <iostream>
#include <string>
#include <sstream>

using namespace std;

int main()
{
    string name = "Joe";
    int age = 55;

    ostringstream os;
    os << name << ": " << age;
    string description = os.str();
    
    cout << description << endl;
    
    return 0;
}

Okay, that works perfectly! Thanks very much!
