What is the usage of the pointer in C?

Answer 1

There is a lot of usage of the pointers in C but here I am mentioning some important usage of the pointer in C which you must know.

• Pointer mostly used in dynamic memory allocation. Using the memory management function we can get the memory during the execution of a program.
• Pointers can be used to access the array elements.
• We can access the memory location with the help of C Pointers.
• Pointers are used in “call by reference”.  In which we can pass the address of a variable ( function, array, ..etc) into a function.
• Pointers are used in complex data structures like linked lists, trees, etc.
