C array declaration and assignment?

Question

I\'ve asked a similar question on structs here but I\'m trying to figure out how C handles things like assigning variables and why it isn\'t allowed to assign them to eachot

Answer 1

Some messages here say that the name of an array yields the address of its first element. It's not always true:

#include 

int
main(void)
{
  int array[10];

  /*
   * Print the size of the whole array then the size of a pointer to the
   * first element.
   */
  printf("%u %u\n", (unsigned int)sizeof array, (unsigned int)sizeof &array[0]);

  /*
   * You can take the address of array, which gives you a pointer to the whole
   * array. The difference between ``pointer to array'' and ``pointer to the
   * first element of the array'' matters when you're doing pointer arithmetic.
   */
  printf("%p %p\n", (void*)(&array + 1), (void*)(array + 1));

  return 0;
}

Output:

40 4
0xbfbf2ca4 0xbfbf2c80
