Here are the answers for the problem:

1. Write an algorithm for the above problem.

  • Step 1: START
  • Step 2: DECLARE three integer variables: number1, number2, number3.
  • Step 3: DECLARE two integer variables: sum, product.
  • Step 4: PROMPT the user to ENTER the first integer.
  • Step 5: READ the first integer and STORE it in number1.
  • Step 6: PROMPT the user to ENTER the second integer.
  • Step 7: READ the second integer and STORE it in number2.
  • Step 8: PROMPT the user to ENTER the third integer.
  • Step 9: READ the third integer and STORE it in number3.
  • Step 10: CALCULATE the sum: sum = number1 + number2 + number3.
  • Step 11: CALCULATE the product: product = number1 * number2 * number3.
  • Step 12: DISPLAY the value of sum.
  • Step 13: DISPLAY the value of product.
  • Step 14: END

2. Write a code in a programming language to implement your algorithm above.

Here is the code implemented in C programming language:

#include <stdio.h> // Required for input/output functions like printf and scanf

int main() {
    // Declare three integer variables for the numbers
    int number1;
    int number2;
    int number3;

    // Declare two integer variables for the sum and product
    int sum;
    int product;

    // Prompt the user to enter the first integer and read it
    printf("Enter the first integer: ");
    scanf("%d", &number1);

    // Prompt the user to enter the second integer and read it
    printf("Enter the second integer: ");
    scanf("%d", &number2);

    // Prompt the user to enter the third integer and read it
    printf("Enter the third integer: ");
    scanf("%d", &number3);

    // Calculate the sum of the three numbers
    sum = number1 + number2 + number3;

    // Calculate the product of the three numbers
    product = number1 * number2 * number3;

    // Display the sum
    printf("The sum of the three numbers is: %d\n", sum);

    // Display the product
    printf("The product of the three numbers is: %d\n", product);

    return 0; // Indicates successful program execution
}

Example Run:

If you compile and run this C program, here's what the console output would look like with sample input:

Enter the first integer: 5
Enter the second integer: 10
Enter the third integer: 2
The sum of the three numbers is: 17
The product of the three numbers is: 100
