Question

Hello everyone! I am working on my assignment for C++ and I'm having a bit of trouble on the value producing functions, I am creating a program wherein I have to input a value and I need to create a function called square value where in it will square the value I have input. I cannot seem to figure out this part. Here is the code that I have so far, and thank you for any help. I greatly appreciate it!

#include <iostream>
using namespace std;
int getValue(); //Prototype Function

int main()
{
   int num
       num = getValue();
   cout << "The value entered is " << num << endl;
   return 0;
}
int getValue()
{
   int val;
   cout << "Enter a number: " << endl;
   cin >> val;
   return val; // Function specifies that it will be returning
}
