Confusion with post increment and logical operator?

Question

    #include 
    #include 

    main()
    {
         int i=-1, j=-1, k=0, l=2,m;
         m = i++&&j++&&k++||l++;
           


        

Answer 1

All that really matters here is the ||. Since l++ evaluates to the boolean 1 (true), the entire statement is true. So m is 1, and the rest are just their original values plus one for the post increment after they are evaluated.

You're evaluating the boolean expression:

((-1 && -1) && 0) || 2

As an aside, your definition of main should be:

int main(void)
