C Language Common C programming idioms and developer practices Comparing literal and variable
Example
Suppose you are comparing value with some variable
if ( i == 2) //Bad-way
{
doSomething;
}
Now suppose you have mistaken == with =. Then it will take your sweet time to figure it out.
if( 2 == i) //Good-way
{
doSomething;
}
Then, if an equal sign is accidentally left out, the compiler will complain about an “attempted assignment to literal.” This won’t protect you when comparing two variables, but every little bit helps.
