Array arguments are really pointers

#include <stdio.h>

void foo(char []);
void bar(char *);
int main()
{
    static char x[100];
    printf("%ld\n",sizeof(x));
    foo(x);
    bar(x);
}

void foo(char x[])
{
    printf("%ld\n",sizeof(x));
}
void bar(char *x)
{
    printf("%ld\n",sizeof(x));
}

I propose that there is no code you can write inside foo() / bar() that would let you tell whether x was declared as [] or * in the argument list. That is to say if the function bodies are identical, the behavior will be identical.
