Write a C program that finds the nth prime number and prints it on the screen. A prime number is a number that is only divisible by 1 and by itself. You need to create a function called FindPrime that obtains the value of n and returns the nth prime number to the main program. The prototype of your function is:

long FindPrime(int n);

The prime numbers are: 2 3 5 7 11 13 17 19 23 29 and so on.

For example, if the user enters 4, your program should print 7 because the 4^th prime number is 7. Or if the user enters 7, your program should print 17 because 17 is the 7^th prime number and so on.

if you can please explain. I am having a hard time understanding this :(
