Hello, could you tell me the difference between the function declared outside main() and inside main()? Thanks in advance! 🙌🏻✨

Question

For example:

int square(int side);
int main()
{
// Code
}
int square(int side){}

****Versus****

int main()
{
int square(int side);
// Code
}
int square(int side){}

Answer 1

Read the code and it's comment to see the difference.

Answer 3

A function declared outside the main() function can be accessed outside the main() function.

Whereas a function declared inside the main() function can *only* be used inside the main() function
