*(a++) is giving error but not *(a+1)?? where a is array name?

Question

In following code:

void main()
{
    char a[]={1,5,3,4,5,6};
    printf(\"%d\\n\",*(a++)); //line gives error: wrong type argument to increment
    printf(\"         


        

Answer 1

a is an array object and not a pointer so you could not use the operation a++ for an array object. because this is equivalent to :

a = a+ 1;

Here you are assigning to the array object a new value which is not allowed in C.

a + 1 return a pointer to the element 1 of your a array and it's allowed
