Explanation: - #include <stdio.h>: This line includes the standard input/output library, which is necessary for using functions like printf and scanf.

  • int main() {: This line marks the beginning of the main function, where the execution of the program starts.

  • int num1, num2, sum;: This declares three integer variables: num1, num2, and sum.

  • printf("Enter first number: ");: This line displays a prompt asking the user to enter the first number.

  • scanf("%d", &num1);: This line reads an integer from the user and stores it in the variable num1.

  • printf("Enter second number: ");: This line displays a prompt asking the user to enter the second number.

  • scanf("%d", &num2);: This line reads an integer from the user and stores it in the variable num2.

  • sum = num1 + num2;: This line calculates the sum of num1 and num2 and assigns the result to the variable sum.

  • printf("Sum: %d\n", sum);: This line prints the sum to the console.

  • return 0;: This line indicates that the program has executed successfully and returns a status code of 0.

  • }: This marks the end of the main function.
