This is correct.

It should be 'p = c'. On the left-hand side of the assignment there
should be an address or LVALUE. On the right-hand side of the
assignment you should have a value or RVALUE. When you do *p on the
left-hand side of the assignment, you are dereferencing the address or
pointer, to get a RVALUE. Hence, the error.

1. Don't use // comments in C coding style.

2. Initialize your pointer variables, or assign NULL to them.

  int *p = NULL;
