   printf("Enter first number and then second number"); //printf function.

   scanf("%d",&first_number); //take the input for the first number.

   scanf("%d",&second_number);//take the input for the second number.

   second_number=(first_number+second_number)-(first_number=second_number);//expression to replace the value.

  printf("The first number is: %d and the second number is: %d after replacement",first_number,second_number); //print the number after replacement.

   return 0;

}
