C Programming: Print individual characters of string in reverse order

C String: Exercise-4 with Solution

Write a program in C to print individual characters of string in reverse order.

Sample Solution:

C Code:

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

void main()
{
    char str[100]; /* Declares a string of size 100 */
    int l,i;
	
       printf("\n\nPrint individual characters of string in reverse order :\n");
       printf("------------------------------------------------------\n"); 	
       printf("Input the string : ");
       fgets(str, sizeof str, stdin);
	   l=strlen(str);
	   printf("The characters of the string in reverse are : \n");
       for(i=l;i>=0;i--)
        {
          printf("%c  ", str[i]);
        }
    printf("\n");
}

The program can also be written as below:

#include <stdio.h>
#include <string.h>
#include <stdlib.h>

void main()
{
    char str[100]; /* Declares a string of size 100 */
    int l=0;
	
       printf("\n\nPrint individual characters of string in reverse order :\n");
       printf("------------------------------------------------------\n"); 	
       printf("Input the string : ");
       fgets(str, sizeof str, stdin);
	   l=strlen(str);
	   printf("The characters of the string in reverse are : \n");
       for(str[l]='\0';l>=0;l--)
        {
          printf("%c  ", str[l]);
        }
    printf("\n");
}

Sample Output:

Print individual characters of string in reverse order :                                                      
-----------------------------------------------------------                                                   
Input the string : w3resource.com                                                                             
The characters of the string in reverse are :                                                                 
                                                                                                              
  m  o  c  .  e  c  r  u  o  s  e  r  3  w
