    You say that when we have a limited space we can use pointer to access all information without creating another varriable, But acutually the pointer itself is a variable that is pointing towards the data. So how does it saves the space as you will have to create a diffrent pointer to access diffrent Data ?

    What is the main use of pointer? For eg. int a=5; a=10; //assigning directly. int *pointer_a; *pointer_a= &a; *pointer_a=10; //assigning change on the memory address. Why to use pointer when we can change the value easily?
