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

I believe this simply could fix the error

#include 

    int main()
    {
        int x = 0;

        if (++x)
            printf("true\n");
        else if (x == 1)
            printf("false\n");
        return 0;
    }
