This is not an ellegant solution, although it works for me.. Just try to get some ideas from this code


MOD EDIT: Please stop giving out the complete solution to problems. We are here to help people to learn to program. Not provide the complete code for them.

Hum, I don't know what you really want, but I guess it's something like this:

#include <stdio.h>

int main(int argv, char *argc[])
{
	FILE *fin;
	char x[20];
	fgets(x, 20, stdin);
	fin = fopen(x, "w");
	
	if(fin != NULL)
		printf("File opened...\n");
	else
		printf("File not opened...");
	
	return 0;
}

Or maybe this, I think this is what you really want:

#include <iostream>
using std::cout;
using std::cin;
using std::endl;


void timeRet(int, int);
int hours;
int minutes;


int main()
{
	cout << "Enter the number of hours:" << endl;
    cin >> hours;
    cout << "Enter the number of minutes:" << endl;
    cin >> minutes;
    timeRet(hours, minutes);
    return 0;
}

void timeRet(int time1, int time2)
{
	cout << time1 << ":" << time2 << endl;
}

Well, using a void function I would do something similar to this:

#include <iostream>
using std::cout;
using std::cin;
using std::endl;


void timeRet();
int hours;
int minutes;


int main()
{
	cout << "Enter the number of hours:" << endl;
    cin >> hours;
    cout << "Enter the number of minutes:" << endl;
    cin >> minutes;
    timeRet();
    return 0;
}

void timeRet()
{
	cout << hours << ":" << minutes << endl;
}

User defined functions are functions that allow the programmer to define there own functions, I mean, functions that are not included in the standard C++ libraries. For example, you could easily write a function to solve the Fibonnaci sequence because as far as I know there isn't any C++ library that includes that.
And remember, always start by the return type, followed by the function name, arguments and then the body of your function
