C Pointers

Used to store memory addresses, providing a way to manipulate and indirectly access data in memory.
Syntax:
data_type *ptr;; data_type - Declaring the type of data in an array i.e; int, float, char, etc.

Example

#include <stdio.h>

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    int *p = arr;
    
    printf("%d\n", *p);
    printf("%d\n", *(p + 1));

    return 0;
}

Declares from Pointer to Pointer

Using the index we can change or modify the values in an array.

Example

#include <stdio.h>

int main() {
    int arr[] = {1, 2, 3, 4, 5};
    int *p = arr;
    
    printf("%d\n", *p);
    printf("%d\n", *(p + 1));

    return 0;
}
