Simple C Statement, Probably "if" syntax

[w_bwr]

ucN2RateKFlg = (ucN2RateKFlg >= 7) ? 1 : (ucN2RateKFlg + 1);

This is a C code. What does this implies?

? : Operator

The ? : operator is just like an if ... else statement except that because it is an operator you can use it within expressions.

? : is a ternary operator in that it takes three values, this is the only ternary operator C has.

? : takes the following form:

if condition is true ? then X return value : otherwise Y value;

It's called a conditional operator.

(ucN2RateKFlg >= 7) is evaluated, then if true, the first operand ofter the ? is returned, otherwise the second (after the : ) is returned.

The result is finally stored in ucN2RateKFlg because of the ucN2RateKFlg =

So, if (ucN2RateKFlg >= 7) is true, 1 will be returned and stored in ucN2RateKFlg otherwise (ucN2RateKFlg + 1) will be returned and stored in ucN2RateKFlg
