Thread: Adding extra characters to output

This little program should give you the idea :

Code:

#include <iostream>
#include <string>

using namespace std;

string makeformat(string oldstring)
{
	string answer;
	
	answer = oldstring.substr(0, 3) + "-" + oldstring.substr(3,2) + "-" + oldstring.substr(5, 4);
	
	return answer;
}

int main()
{
	string string1 = "123456789";
	string newstring;
	
	newstring = makeformat(string1);
	
	cout << newstring << endl;

                return 0;
}
