Address of the First Element of an Array

Home > C > General

Q

When does the compiler not implicitly generate the address of the first element of an array?

✍: FYIcenter

A

Whenever an array name appears in an expression such as:

array as an operand of the sizeof operator
array as an operand of & operator
array as a string literal initializer for a character array

Then the compiler does not implicitly generate the address of the address of the first element of an array.
