Answer 1

# include

# include

int ch,r,a,h,d,l;

float Ac, Ar, At;

void main()

{

clrscr();

printf("\n press1,area of circle");

printf("\n press2,area of rectangle");

printf("\n press3,area of triangle");

printf("\n enter your choice");

scanf("%d",&ch);

switch(ch)

{

case 1: printf("\n enter values to find area of circle");

scanf ("%d",&r);

Ac = 3.14*r*r;

printf("\n area of circle is %f",Ac);

break;

case 2: printf("\n enter values to find area of rectangle ");

scanf("%d%d",&a,&h);

Ar= a*h;

printf("\n area of rectangle is %f",Ar);

break;

case 3: printf("\n enter values to find volume of cylinder");

scanf("%d%d",&d,&l);

At = 0.5*d*l;

printf("\n area of triangle is %f",At);

break;

DEFAULT: printf("\n enter the proper choice");

}

getch();

}
