In this tutorial you will learn about the C Program to Reverse an Array and its application with practical example.
C Program to Reverse an Array
In this tutorial, we will learn to create a C program that will reverse the element of Array using C programming.
Prerequisites
Before starting with this tutorial we assume that you are best aware of the following C programming topics:
- Operators in C Programming.
- Basic Input and Output function in C Programming.
- Basic C programming.
- For loop in C Programming.
The reverse of the array:-
As we all know array is a collection of similar data type elements. In an array, only one variable is declared which can store multiple values. First will take the number of elements of an array from the user. Then will take the elements from the user for the array. And at last, we will reverse the array using C Programming Language.
Algorithm:-

STEP 1: START STEP 2: INITIALIZE arr[] = {25, 11, 7, 75, 56} STEP 3: length= sizeof(arr)/sizeof(arr[0]) STEP 4: min = arr[0] STEP 5: SET i=0. PRINT ARRAY i<lenght NORMAL ORDER STEP 6: SET i=lenght -1 THEN PRINT STEP 7: i=i-1. STEP 8: PRINT "REVERSE ORDER OF ARRAY IS AS FOLLOWS" STEP 9: RETURN 0. STEP 10: END. |
Program:-
To Reverse element from the array

#include<stdio.h> int main() { //fill the code; int n; //Input form user number of elements of array printf("Enter the number of elements of array :-\n"); scanf("%d",&n); int arr[n]; int i; //Input form user elements of array printf("Enter the of elements of array :-\n"); for(i = 0; i < n; i++) { scanf("%d",&arr[i]); } //Output Reverse elements of array printf(“Reversed array is:\n”); for(i = n-1; i >= 0; i--) { printf("%d\n",arr[i]); } return 0; } |
Output:-
In the above program we have first initialized the required variable
n
- arr = it will hold the elements in an array.
- n = it will hold the number of elements in an array.
- i = it will hold the integer value to control the array.
- size = it will hold the size of array.
