Modularizing and Reusing of code through Functions
Calculation of the area of a circle is separated into a separate module, from the calculation of an area of a ring, and the same module can be reused multiple times.
/* Program to find area of a ring */
#include<stdio.h>
int main()
{
float a1,a2,r1,r2;
printf(“enter the radius:”);
scanf(“%f”,&r1);
a1=3.14*r1*r1;
printf(“enter the radius:”);
scanf(“%f”,&r2);
a2=3.14*r2*r2;
a=a1-a2;
printf(“Area of ring: %3f\n”,a);
}
To understand, modularization and reusing of code through functions, let us consider the following program
Calculation of an area of a Circle from the calculation of an area of the ring and the same module can be reused a multiple times.
The calculation of an area of a ring, using repeated and reusable blocks of code is shown on the screen.
Here, blocks of code highlighted on the screen are used to find the areas of two circles from which the area of the ring is calculated as ‘a1-a2’ which is stored in ‘a’ and returned.
