Why this code which is posted on howstuffworks.com does not work? [closed]

by

Arrays used as operand of operatiors except for sizeof and unary & are automatically converted to a pointer that points at the first element of the array.
The converted pointer is not a lvalue, so it cannot be used as the left operand of assignment operator.

This code works.

#include <stdio.h>

int main(void)
{
    int a[5];
    int i;

    for (i=0; i<5; i++)
        a[i] = i;
    for (i=0; i<5; i++)
        printf("a[%d] = %d\n", i, a[i]);
    return 0;
}
