How to write a C Program to calculate Area, Perimeter of Rectangle; Area, Circumference of Circle in C Programming Language ?
Solution:
- The program helps you calculate the area and perimeter of a rectangle.
- It also calculates the area and the circumference of the circle.
- The values of Length, Breadth and Radius are to be entered through the keyboard.
The length and breadth of a rectangle and radius of a circle are input through the keyboard. Write a program to calculate the area and perimeter of the rectangle, and the area and the circumference of the circle.
/*
aor: area of rectangle
por: perimeter of rectangle
aoc: area of circle
coc: circumference of circle
*/
aor: area of rectangle
por: perimeter of rectangle
aoc: area of circle
coc: circumference of circle
*/
The circumference of a circle is same as the perimeter that is the distance around the outer edge.
The formula of circumference is = 2 pi r (pi's symbol)
where r = the radius of the circle
and pi = 3.14(Approx)
where r = the radius of the circle
and pi = 3.14(Approx)
- #include <stdio.h>
- //C program to find Area and Circumference of a Circle with Sample Input and Output.
- main()
- {
- float length, breadth, radius, aor, por, aoc, coc;
- printf ("\nEnter the Length and Breadth of the Rectangle: ");
- scanf("%f %f", &length, &breadth);
- printf("\nEnter the Radius of the Circle: ");
- scanf("%f", &radius);
- aor = length*breadth;
- por= 2*(length+breadth);
- aoc = 3.14*radius*radius;
- coc = 2*radius*3.14;
- printf("\nThe area of the rectangle is: %f", aor);
- printf("\nThe perimeter of the rectangle is: %f ", por);
- printf("\n\nThe area of the Circle with radius %f is: %f ", radius, aoc);
- printf("\nThe circumference of the same circle is: %f", coc);
- }
