Question

I have seen this syntax in a program but I am not sure what happens at the return part. What does the ||(or) mean? Does this mean that the method returns true when at least one of a and b is true and returns false when both of them are false?

    bool A::truthValue() {
    bool a = true;
    bool b = true;
    if(........)
       a= false;
    if(........)
       b=false

    return (a || b);
}

Answer 1

It will return true if either b or a is true. This means that the result is (see table):

a | b | result
t | t | t
f | t | t
t | f | t
f | f | f

Actually in your specific case, false will be returned only if both if statements become true.

EDIT So – your suggestion is correct.
