say i have a function foo
Code:
foo(char* s, num){

}

thanks for the link! thumb.gif
so is this plausible?
Code:
// Exam.cpp : main project file.

#include "stdafx.h"
#include <string>
using namespace std;


public string foo(string s, int num){
        string newS = s;
        int newNum = num;
        return newS.substr(1, num);
}


int main()
{
        string s = "overclock";
        int num = 4;
        foo(s, num);

    return 0;
}
