What can i do with pointers ..why they are important ?

Answer 1

to get the data or access strings in array

Answer 2

Rio, when we need to access strings arrays , or when we use pass by reference arguments then, we cannot do it without pointers

(* ) it's used to create pointer variables pointing at memory address of some variable

(&) this address operator is used to create the actual memory address value of the variable

int a=3;
but &a is memory address where 3 is stored , so some hexadecimal value.

we use pointers to use equality operations indirectly using address value s
