Assuming it is allocated some space, then it's
*struct->j
Oh, and you really need to get a compiler ASAP.
If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
If at first you don't succeed, try writing your phone number on the exam paper.
Now i am using mobile browser so please any one and help me to understand it...
Thank you salem ...So now if i want to access the pointer variable in the structure means i want to use this
am i correct...Code:*ptr->j=20;

I think you mean struct->j or (*struct).j.Originally Posted by Salem
This isn't a struct** after all.
No, it's ptr->j or (*ptr).j.
Your main delcaration is incorrect too, see signature.
And you haven't allocated any memory for your pointer in the sample either, so you will get an access violation when you run that code.
