Problem Statement :
Write a program to access elements using pointer.
Code:
#include <stdio.h>
int main() {
//57. Write a program to access elements using pointer.
printf("\tElements Of Array\n");
printf("===================================\n\n");
int arr[5] = {18, 19, 20, 21, 22};
int *ptr;
int i;
ptr = arr;
for (i = 0; i < 5; i++) {
printf("\nThe value of element %d is: %d\n", i, *(ptr + i));
}
return 0;
}
Description :
- This is a program written in C language that demonstrates how to access array elements using a pointer.
- The program includes the standard input-output library
stdio.h. - The
main()function is defined. - Two variables of
intdata type are declared:arrwhich is an array of 5 integers, andptrwhich is a pointer to an integer. - An integer variable
iis declared. - The pointer
ptris initialized to the base address of the arrayarr. - A
forloop is used to iterate over the array. The loop variableiis used to index each element of the array. - The value of each element in the array is accessed using the pointer
ptr. The expression*(ptr + i)gives the value of thei-th element of the array. - The value of the
i-th element is printed usingprintf()function. - Finally, the
main()function returns an integer value 0.
