Program:

#include<stdio.h>
#include<conio.h>
int main()
{
	int n;
	float rad,area,nsq,length,breadth;
	printf("enter any number\n");
	scanf("%d",&n);
	switch(n)
	{
		case 1:
			printf("\nplease enter the radius of the circle\n");
			scanf("%f",&rad);
			area=3.14*rad*rad;
			printf("\nArea of circle: %f",area);
	    break;
	    
	    case 2:
	    	printf("please enter the lenght of side of the square:");
			scanf("%f",&nsq);
			area=nsq*nsq;
			printf("\nArea of rectangle: %f",area);
			
	    	
	    break;
	    
	    case 3:
	    		printf("please enter the lenght  of the rectangle:");
	    		scanf("%f",&length);
	    		printf("enter the breadth of the rectangle:");
	    		scanf("%f",&breadth);
	    		area=length*breadth;
	    		printf("\nArea of rectangle: %f",area);
	    break;
	    
	    default:
	    	printf("invalid choice");
	}
	
}

Output:

enter any number
1

please enter the radius of the circle
3

Area of circle: 28.260000
enter any number
2
please enter the lenght of side of the square:4

Area of rectangle: 16.000000
enter any number
3
please enter the lenght  of the rectangle:4
enter the breadth of the rectangle:3

Area of rectangle: 12.000000
