Answer 1

In order to call a function, the compiler must know the prototype of it. If you wish to have your function follow main, declare the prototype before main and it will work. Putting this before main, allows the definition to be after:
int print();

Answer 2

main is a function where the program execution starts. Every program has a main function.

Answer 3

You cannot use a function or variable which is not yet declared.
eg:

x = 3; // x not yet declared
int x;

This is wrong. Because the compiler doesn't know what x is and you are using it.🤐

Correct way:
int x;. // first declare x
x = 3;

Likewise:

int print();. // first declare the function

int main(){
print();
}

int print(){
cout<<"You got it?";
}
