Array subscript error

main( )

{

  int a[ ] = {10,20,30,40,50},j,*p;

  for(j=0; j<5; j++)

    {

printf(“%d” ,*a);

a++;

    }

    p = a;

   for(j=0; j<5; j++)

      {

printf(“%d ” ,*p);

p++;

      }

 }

Answer:

Compiler error: lvalue required.

        

Explanation:

Error is in line with statement a++. The operand must be an lvalue and may be of any of scalar type for the any operator, array name only when subscripted is an lvalue. Simply array name is a non-modifiable lvalue.
