Thank you for your post! You can try the below to fix your code.

#include <iostream>  
using namespace std;  
  
int change(int num1);  
  
  
int main()  
{  
    int a = 10;  
    int changeNumber;  
  
    cout << a << endl;  
    changeNumber = change(a);  
    cout << changeNumber << endl;  
    return 0;  
  
}  
  
  
int change(int a) {  
    int changed = a + 10;  
  
    return changed;  
}  

Thank you for your time and patience throughout this issue.
