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

In the C language, there is no method to determine the size of an unknown array, so the quantity needs to be passed as well as a pointer to the first element.
