  • This program is used to print the sum of two numbers.
  • Three integer variables number1, number2 and sum are initialized.
  • On execution, the program requests the user to enter two numbers using scanf() function and these inputs are stored in the respective variables.
  • A variable sum is initialized that holds an addition operation. The two numbers are added using the + operator and their result is stored in the variable sum.
  • The printf() function prints the variable sum and displays the result on the screen.
  • The return 0 statement exists the program.
