Question

Write an algorithm that compute the area of a square

Answer 1

The program to compute area of a square is :-

#include <stdio.h>

int main()

{

   float side, area;

   printf("Enter the sides of a square :- ");

   scanf("%f",&side);

   area= side* side;

   printf("Area of a Square is :- %0.2f", area);

}

Output -

Enter the sides of a square :- 2                                                                                                              

Area of a Square is :- 4.00

Algorithm -

Step 1 - Start

Step 2 - Declare floating type variables

Step 3 - Read value for side of square

Step 4 - Multiply sides and store the result

area <- side * side

Step 5 - Display area of square

Step 6 - Stop

Answer 2

Answer:

Algorithm for area of a square:

Explanation:

An algorithm is nothing but a set of rules written, which are to be followed in calculations or in other problem-solving operations especially in a computer.

Algorithms are the most important steps in programming.

Algorithms must terminate after a finite number of steps.

Now, the algorithm for the area of  a square will be as follows:

START

ACCEPT THE SIDE OF SQUARE SAY a

COMPUTE THE AREA WITH THE HELP OF FORMULA A = $a^{2}$

DISPLAY RESULT

STOP
