Is there a difference in the order of the comparison operator?

#define CONST_VALUE 5

int variable;

...

if ( variable == CONST_VALUE )   // Method 1
...

OR

if ( CONST_VALUE == variable )   // Method 2
...

Is this simply a matter of preference or is there a compelling reason for a particular comparison order?

    The reason some people use method 2 is because you’ll get a compiler error if you mistype a = in place of the ==.

    However, you’ll have people (like me) who will still use method 1 because they find it more readable and if there is an error, it will be detected during testing (or, in some cases, static analysis of the code).
