c++ handling

  1. Declare the necessary header file with the #include directive, for example: #include .
  2. Define the main function using the int main() {} structure.
  3. Within the main function, declare variables as needed, for example: int num1, num2, sum;.
  4. Prompt the user for input using the std::cout and std::cin functions, for example: std::cout << "Enter first number: "; std::cin >> num1;.
  5. Perform the desired operation, for example: sum = num1 + num2;.
  6. Display the result using std::cout, for example: std::cout << "The sum is: " << sum << std::endl;.
  7. Use the return 0; statement to indicate successful completion of the program.
