# C Exercises: A menu-driven program to compute the area of the various geometrical shape

## C Conditional Statement: Exercise-25 with Solution

Write a program in C which is a Menu-Driven Program to compute the area of the various geometrical shape.

Pictorial Presentation: Sample Solution:

C Code:

``````#include <stdio.h>
void main ()
{
int choice,r,l,w,b,h;
float area;
printf("Input 1 for area of circle\n");
printf("Input 2 for area of rectangle\n");
printf("Input 3 for area of triangle\n");
scanf("%d",&choice);
switch(choice)
{
case 1:
printf("Input radious of the circle : ");
scanf("%d",&r);
area=3.14*r*r;
break;
case 2:
printf("Input length and width of the rectangle : ");
scanf("%d%d",&l,&w);
area=l*w;
break;
case 3:
printf("Input the base and hight of the triangle :");
scanf("%d%d",&b,&h);
area=.5*b*h;
break;
}
printf("The area is : %f\n",area);
}
```
```

Sample Output:

```Input 1 for area of circle
Input 2 for area of rectangle
Input 3 for area of triangle
Input radious of the circle : 5
The area is : 78.500000
```
