main( )

{

float a,b, ad,sb,mul,div;

printf(“/n enter value of a,b”);

scanf(“%f%f”,&a,&b);

ad=a+b;

sb=a-b;

mul=a*b;

div=a/b;

printf(“/n addition =%f”,ad);

printf(“/n subtraction=%f”,sb);

printf(“/n multiplication =%f”,mul);;

printf(“/n division =%f”, div);

}

Write a program to input a string by using “gets” function and then print it on the screen by using the “puts” function (Gets Function)

Input the radius of a sphere. Compute its volume and surface area(“Formula for surface area=4 TT r2 and volume=4/3TTr3 and TT=3.1417(Scanf)

main( )

{

float r,v, area;

clrscr();

printf(“Enter radius of sphere?”);

scanf(“%F”,&r);

area=4.0*3.1417*r*r;

v=(4.0/3.0)*3.1417*r*r*r;

printf(“Volume of sphere =%f/n”,v);

printf(“area of sphere=%f/n”,area);

getch();

}
