what is the use of -> in c.can we use it in all programming languages

Can you use it in all programming languages? Only if the programming language recognizes -> as a valid operator.

a->b is equivalent to (*a).b . It's syntactic sugar for accessing members of a structure through a pointer to an instance of the structure.
