why we use pointer im the programme

Answer 1

Pointers are used for a lot of things. The most common use is for "Dynamic Memory Allocation" which cannot be performed without the use of pointers.

Some other use cases are to pass a function as a parameter to another function or efficient handling of large amounts of data as you can use pointers to pass a large struct/class to a function without copying the entire struct/class.

Answer 2

Pointers allow dynamic memory management. This means you can access memory more efficiently and with less usage of your memory. The memory managed by pointers is only reserved dynamically when necessary.
