@Harshit it is giving output :- ba$ ( when I used cout << p; I don't know the reason. I am too new to c++. But I am going to ask this in a post or on discord server of the sololearn.

Hey pal, thanks so much trying to help me. But this one, I already knew that it shows the address of p but what I don't get is why does it show 'ba'? why 'a' after 'b' ?
