C program uses pointers to access array elements

Comprehensive Collection of C Programming Examples

In this example, you will learn how to use pointers to access array elements.

To understand this example, you should be familiar with the followingC programming languageTopic:

• C for loop

• C arrays

• C pointers

• The relationship between arrays and pointers

Using pointers to access array elements

#include <stdio.h>
int main() {
　　　　int data[5];
　　　　printf("Input element: ");
　　　　for (int i = 0; i <　5;　++i)
　　　　　　　　scanf("%d", data　+　i);
　　　　printf("You input: \n");
　　　　for (int i = 0; i <　5;　++i)
　　　　　　　　printf("%d\n",　*(data　+　i));
　　　　return 0;
}

Output result

Input element:　1
2
3
5
4
You input:　
1
2
3
5
4

Then, use the pointer symbol to access the elements of the array. By the way,

• data[0] is equivalent to* data, &data[0] is equivalent to data

• data[1] is equivalent to*(data + 1) &data[1] is equivalent to data + 1

• data[2] is equivalent to*(data + 2) &data[2] is equivalent to data + 1

• ...

• data[i] is equivalent to*(data + i), &data[i] is equivalent to data + i
