Find The Nth Prime Number

HHV234 (1)
Hi - I am brand new to C++ and am just learning about functions and passing arguments between functions.

Below is my program. In the function int Prime (int n) I am trying to somehow take the code from bool is prime(int num) to determine the nth location of a prime number. Any help is greatly appreciated!

using namespace std;

bool IsPrime(int); //function declaration before it is called, specifies type
int Prime(int); //function declaration before it is called
void main()
{
	char response;
	int n, num, count=0;


	do {
		cout << "Enter F to find the Nth prime number: " << endl;
		cout << "Enter T to test the value to see if it is prime: " << endl;
		cout << "Enter Q to terminate the program: " << endl;

			cin >> num;
			if (num > 0) {
				if (IsPrime(num) == false) {
					cout << "Your Number Is Not Prime";
				}
				else {

				cout << "Enter a Value Greater Than Zero: ";
				cin >> n;
				if (n > 0) {
					cout << "The nth Prime Number where n is " << n << " is " << Prime(n)<< endl;
				}
				else cout << "Your Number Is Invalid."; //get rid of prompt here?
			}
		}

	} 
	while (response != 'Q'); //used code while (response !='Q' || response !='q') 
	//and will not work for either Q or q when or is entered


}
	// for 'T' Value
bool IsPrime(int num) // function declarator 
{

	for (int j = 2; j <= num / 2; j++)
		if (num % j == 0)
			return false; //not prime
	
	return true; //is prime
}
	// for 'F' Value
	int Prime(int n) // function declarator
	{
		int count = 0;
		while (IsPrime(n) == false){
			return count++; 
		}
	}

Your problem doesn't have anything to do with passing arguments. Prime will always return 0. Trace the logic to discover why.
