How does the increment operator work in an if statement?

Question

    #include 

    int main()
    {
        int x = 0;

        if (x++)
            printf(\"true\\n\");
        else if (x == 1)
            printf(         


        

Answer 1

You yourself wrote: "x++ is post increment, this means that the value of x is used then it is incremented"

Consider what that means:

1. x is 0

2. The expression is evaluated, 0 is false, so the expression is false.

3. The post increment happens, changing x from 0 to 1.
   (After the expression was evaluated)
