1. Is it a correct initialization of pointer p    int **p = NULL;
2.In K & R it is mentioned that a unioh may be initialized with a value of it's 
first member.But following code works fine.   int main(int argc, char 
*argv[])  {
    union ua{    int a;    float b;        } utest;    utest.b = 20.01;    
return 0;    }
I wanted to know correct interpretation of the above statement
