Compiler Warning (level 4) C4130

'operator ' : logical operation on address of string constant

The operator was used with the address of a string literal. Unexpected code was generated.

For example, the following code generates this warning:

char *pc;
pc = "Hello";
if (pc == "Hello")
   { }

The if statement compares the value stored in the pointer pc to the address of the string "Hello", which is allocated separately each time the string occurs in the code. The if statement does not compare the string pointed to by pc with the string "Hello".

To compare strings, use the strcmp function.
