In C, except for a few special cases, an array reference always "decays" to a pointer to the first element of the...

Though an array is passed as a reference parameter an & is not used to denote a reference parameter. However it must be indicated to the compiler that this parameter is an array by appending [] to the formal parameter name. read less

Because, it also need one more argument i.e., a size of an array. Therefore arrays are usually passed by pointers
