Here’s one I made. I didn’t really look at this too much but I use my knowledge from java here:

#include // tells compiler what cout and endl do double num; // declare variables double num1; // double means you can use decimals!


int main() // program runs main

{

using namespace std; // make life easier, instead of std::cout and std::endl
   cout << "Welcome to my calculator! \n" << endl; // displays welcome!

   cout << "Please enter your first number:" << endl; // tells user to enter num

   cin >> num;  // lets person enter num and stores it into num

   cout << "Please enter your second number:" << endl; // tells user to enter num1

   cin >> num1; // lets person enter num1 and stores it into num1

   cout << "The result is: " << num + num1  << endl; // Add num + num1

system("pause"); // Pauses the cmd from closing. return 0; // return nothing }
