Reversing Strings and Digits Using C Programming Language.

 Reverse Of String and Digits 

Welcome to this tutorial where you will learn how to reverse strings and digits using the C programming language. Reversing a string or a set of digits is a common task in programming, and it is essential to have this skill as it is required in many programming tasks.

In this tutorial, we will provide you with a comprehensive guide to reversing strings and digits using the C programming language. We will cover different methods to perform this operation, including using loops, arrays, and functions.

You will learn how to write a C program to reverse strings and digits and we will provide you with easy-to-understand examples and clear explanations of the process.

For example, we will show you how to take a string like "codingfizz" and reverse it to "zzifgnidoc", and how to reverse a set of digits like "23456" to "65432".

By the end of this tutorial, you will have a strong understanding of how to reverse strings and digits using C programming language, and you will be able to implement this skill in your future programming tasks.

Reverse a String in C language:

There are many ways to print a reverse string using C language.

• Reverse a string using strrev() function.

#include <stdio.h>
 #include <string.h>
 int main(){
    char str[50];
    printf("Enter a String: ");
    scanf("%s",&str);
    printf("Reversed of given String: %s",strrev(str)); 
    return 0;
 }

Output:

Enter a String: codingfizz

Reversed of given String: zzifgnidoc

You can also reverse digits with the help of the above code.

Output:

Enter Digits: 23425

Reversed of given Digits: 52432

• Reverse a string using loops. 

#include <stdio.h>    
 #include <string.h>  
 void main()  
 {  
    char str[50], temp; 
    int i, l, r, len;  
    printf (" \n Enter a string: ");  
    scanf( "%s", &str); 
    len = strlen(str);
    l = 0;  
    r = len - 1; 
    for (i = l; i <r; i++)  
    {  
        temp = str[i];  
        str[i] = str[r];  
        str[r] = temp;  
        r=r-1;  
    }  
    printf ("Reversed of given String: %s ",  str);    
 }  

Output:

Enter a String: codingfizz

Reversed of given String: zzifgnidoc

You can also reverse digits with the help of the above code.

Output:

Enter Digits: 23425

Reversed of given Digits: 52432

Reverse a Digits in C language:

#include <stdio.h>    
 #include <string.h>  
 void main()  
 {  
   int num, digit, reverse=0;
   printf("Enter Digits: ");
   scanf("%d",&num);

    while(num>0){
        digit=num%10;
        reverse=(reverse*10)+digit;
        num=num/10;
    }
    printf ("Reversed of given Digits: %d ",  reverse);
 }  

Output:

Enter Digits: 23425

Reversed of given Digits: 52432
