Why is it that you have to allocate and initialize all values in the variable ball and then execute using NSLog when you can simply use Sphere which is the object consisting of all the information that is being passed into the variable ball would it not be the same thing. I have tried and it did fail to execute, i would like to know why?

int main() { // Sphere *ball = [[Sphere alloc] init];

[Sphere setRadius:25];
NSLog(@"ball radius %@", [Sphere radius]);

return 0;
