How to print the elements in a reverse order from an array in C?


Try to print the elements in reverse order by following an algorithm given below −

Step1 − Declare an array of size 5

Step 2 − Enter the 5 elements in memory using for loop

Step 3 − Display elements in reverse order

By decrementing for loop

The only logic is to reverse the elements is For loop −

for(i=4;i>=0;i--){
   //Displaying O/p//
   printf("array[%d] :",i);
   printf("%d\n",array[i]);
}

Example

Following is the C program to reverse the elements −

#include<stdio.h>
void main(){
   //Declaring the array - run time//
   int array[5],i;
   //Reading elements into the array//
   printf("Enter elements into the array: \n");
   //For loop//
   for(i=0;i<5;i++){
      //Reading User I/p//
      printf("array[%d] :",i);
      scanf("%d",&array[i]);
   }
   //Displaying reverse order of elements in the array//
   printf("The elements from the array displayed in the reverse order are :\n");
   for(i=4;i>=0;i--){
      //Displaying O/p//
      printf("array[%d] :",i);
      printf("%d\n",array[i]);
   }
}

Output

When the above program is executed, it produces the following result −

Enter elements into the array:
array[0] :23
array[1] :13
array[2] :56
array[3] :78
array[4] :34
The elements from the array displayed in the reverse order are:
array[4] :34
array[3] :78
array[2] :56
array[1] :13
array[0] :23
