Implement an algorithm in Pascal or C that takes two integers, calculates their product, and displays the result.

Here are the completed codes for both Pascal and C:

Pascal code

Program product;
Var num1, num2, Prod : integer;
Begin
  Write('Give an integer');
  Readln(num1);
  Write('Give another integer');
  Readln(num2);
  Prod := num1 * num2;
  Writeln('The value of Prod: ', Prod);
End.

C code

#include <stdio.h>
int main () {
  int num1, num2, Prod;
  printf("Give an integer\n");
  scanf("%d", &num1);
  printf("Give another integer\n");
  scanf("%d", &num2);
  Prod = num1 * num2;
  printf("The value of Prod: %d\n", Prod);
  return 0;
}

Explanation of steps:

1. Variable Declaration:
   • In Pascal: Var num1, num2, Prod : integer; declares three integer variables.
   • In C: int num1, num2, Prod; declares three integer variables.
2. Input First Integer:
   • In Pascal: Write('Give an integer'); displays the prompt, and Readln(num1); reads the integer into num1.
   • In C: printf("Give an integer\n"); displays the prompt, and scanf("%d", &num1); reads the integer into num1.
3. Input Second Integer:
   • In Pascal: Write('Give another integer'); displays the prompt, and Readln(num2); reads the integer into num2.
   • In C: printf("Give another integer\n"); displays the prompt, and scanf("%d", &num2); reads the integer into num2.
4. Compute Product:
   • In Pascal: Prod := num1 * num2; calculates the product and assigns it to Prod.
   • In C: Prod = num1 * num2; calculates the product and assigns it to Prod.
5. Display Product:
   • In Pascal: Writeln('The value of Prod: ', Prod); displays the calculated product.
   • In C: printf("The value of Prod: %d\n", Prod); displays the calculated product.
