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

Try to print the elements in reverse order as per the algorithm given below:

Step 1 - Declare an array of size 5

Step 2 - Use a for loop to input the 5 elements into memory

Step 3 - Display the elements in reverse order

For loop by decrement

The only logic is to reverse the elements through the for loop:

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

Example

The following is the C program to reverse the elements −

Online Demonstration

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

Output

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

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
