C program to Reverse an Array

 

Consider the following I/O samples to reverse an array.

SAMPLE INPUT:  a = {10,20,50,60,70}

SAMPLE OUTPUT: a={70,60,50,20,10}

The algorithm used here is :

1. Input the number of elements
2. Input the array elements
3. Traverse the array  ---> for(i=n-1;i>=0;i--)
4. Print the reversed array.  

C PROGRAM:  

#include<stdio.h>

int main()

{

   int arr[100];

   int i, n;

   printf("Enter the number of elements:");

   scanf("%d",&n);

   for(i=0;i<n;i++)

   scanf("%d",&arr[i]);

   printf("The Reversed Array is:\n");

   for(i=n-1;i>=0;i--)    // traversing the array

   printf("%d\t", arr[i] ); 

   return (0);

}

OUTPUT:

The given source code in C program to Reverse an Array is short and simple to understand. The source code is well tested in DEV-C++ and is completely error free.
