C==a is false, c=a is an expression, a value is assigned to c, the equivalent of c=a, the if (c)

If don't I what matter, said very understand,
Use a colon equal sign: early language=said assignment, because assignment occur more often than the equivalent operation, so an equal sign said assignment, two equal values are equal,

In work, if must write the if (x==0) (! It is safe to x),
