int *hh=I_1(x+1)

What does this mean exactly? Thanks

It means what it says.
Declares a variable hh of type int* and initializes it to the return value of I_1, which is called with x+1 as a parameter.

Sorry but what is I_1?

Hi ,
it look like the function that is returning the int data type.

I_1 is not a keyword, nor a standard library function. It could be function someone created, or much less likely some type that is constructable with a single argument and is convertible to int *. It can also be a preprocessor macro that expands to some other expression.
