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");
printf("Input your choice : ");
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 your choice : 1 Input radious of the circle : 5 The area is : 78.500000

C Programming: Tips of the Day
Why do C and C++ compilers allow array lengths in function signatures when they're never enforced?
It is a quirk of the syntax for passing arrays to functions.
Actually it is not possible to pass an array in C. If you write syntax that looks like it should pass the array, what actually happens is that a pointer to the first element of the array is passed instead.
Since the pointer does not include any length information, the contents of your [] in the function formal parameter list are actually ignored.
