printf("Enter your choice:\n");
choice = input();
switch (choice) {
case 1: {
printf("Enter radius:\n");
num = input();
result = 3.14 * num * num;
printf("Area of sphere=");
output(result);
break;
}
case 2: {
printf("Enter side of square:\n");
num = input();
result = num * num;
printf("Area of square=");
output(result);
break;
}
case 3: {
printf("Enter radius:\n");
num = input();
result = 4 * (3.14 * num * num);
printf("Area of sphere=");
output(result);
break;
}
