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 a string in reverse order.

Sample Solution:

C Code:

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

int main() {
    char str[100]; /* Declares a string of size 100 */
    int l, i; // Declare variables for string length and loop iteration

    printf("\n\nPrint individual characters of string in reverse order :\n"); // Display information about the task
    printf("------------------------------------------------------\n");
    printf("Input the string : ");

    // Read a string from the standard input (keyboard) using fgets()
    fgets(str, sizeof str, stdin);

    l = strlen(str); // Calculate the length of the string

    printf("The characters of the string in reverse are : \n");

    // Loop to print each individual character of the string in reverse order
    for (i = l - 1; i >= 0; i--) {
        printf("%c  ", str[i]); // Print each character in reverse order
    }

    printf("\n");
	
	return 0; // Return 0 to indicate successful execution of the program
}

The program can also be written as below:

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

int 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");
	
	return 0; // Return 0 to indicate successful execution of the program
}

Sample Output:

Print individual characters of string in reverse order :                                                      
-----------------------------------------------------------                                                   
Input the string : w3resource.com                                                                             
The characters of the string in reverse are :
