Why isn't the size of an array parameter the same as within main?

Question

Why isn\'t the size of an array sent as a parameter the same as within main?

#include 

void PrintSize(int p_someArray[10]);

int main () {
           


        

Answer 1

The behavior is by design.

Same syntax in function parameter declaration means completely different thing than in local variable definition.

The reason is described in other answers.
