Algorithm to Find Area Of Rectangle

Use the following algorithm to write a program to find area of rectangle; as follows:

  1. Take input length and width of rectangle. Store it in two different variables.
  2. Calculate area of rectangle using area = length * width.
  3. Finally, print the value of area of rectangle.

C Program to Find Area Of Rectangle using Formula

#include<stdio.h>
int main()
{
	float length,breadth,area;
	
	printf("enter length of rectangle: ");
	scanf("%f",&length);
	
	
	printf("enter breadth of rectangle: ");
	scanf("%f",&breadth);
 
	area=(length*breadth);
	printf("Area of Rectangle: %f\n",area);
	return 0;
}

The output of the above c program; as follows:

enter length of rectangle: 10
enter breadth of rectangle: 30
Area of Rectangle: 300.000000

C Program to Find Area Of Rectangle using Function

#include<stdio.h>
float area(float l,float b)
{
	return (l*b);
}
 
int main()
{
	
	float l,b,a;
	
	printf("enter length of rectangle: ");
	scanf("%f",&l);
	
	
	printf("enter breadth of rectangle: ");
	scanf("%f",&b);
 
	a=area(l,b);
	printf("Area of Rectangle: %f\n",a);
	return 0;
}

The output of the above c program; as follows:

enter length of rectangle: 50
enter breadth of rectangle: 25
Area of Rectangle: 1250.000000

C Program to Find Area Of Rectangle using Pointer

#include<stdio.h>
void area(float *l,float *b,float *area)
{
	*area=((*l)*(*b));
}
 
int main()
{
    
float l,b,a;
	
	printf("enter length of rectangle: ");
	scanf("%f",&l);
	
	
	printf("enter breadth of rectangle: ");
	scanf("%f",&b);
 
	area(&l,&b,&a);
	printf("Area of Rectangle: %f\n",a);
	return 0;
}

The output of the above c program; as follows:

enter length of rectangle: 55
enter breadth of rectangle: 15
Area of Rectangle: 825.000000
