My first function – C++ Program

What it does: 

Just a simple function which I created where it uses parameter. Within the function 1 is added onto the variable which is then returned. Within the main the variables value is set to 20, therefore it is going to increment to 21 once the function is added on. At the end of the program the variable is printed out.


#include <iostream>
using namespace std;
int AddOne(int start)
  int newnumber;
  newnumber = start + 1;
  return newnumber;
int main()
  int testnumber;
  int result;
  testnumber = 20;
  result = AddOne(testnumber);
  cout << result << endl;
  return 0;

  1. Happy to see a new programmer in town. Wish you all success. Since I don’t see python in the list above (I hope to see you).
