Sort a String in Alphabetical order


Write a C Program to Sort a String in Alphabetical order. Here’s simple C Program to Sort a String in Alphabetical order in C Programming Language.


C – Strings : 


Strings are actually one-dimensional array of characters terminated by a null character ‘\0’. Thus a null-terminated string contains the characters that comprise the string followed by a null.

String is a sequence of characters. char data type is used to represent one single character in C. So if you want to use a string in your program then you can use an array of characters.

The declaration and definition of the string using an array of chars is similar to declaration and definition of an array of any other data type.

Any string ends with a terminating null character ‘\0’. An array definition in such a way should include null character ‘\0’ as the last element.


Here is source code of the C Program to Sort a String in Alphabetical order. The C program is successfully compiled and run(on Codeblocks) on a Windows system. The program output is also shown in below.


SOURCE CODE : :


/*  C Program to Sort a String in Alphabetical order  */

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

int main()
  {
     char str[10],temp;
     int i,j;

     printf("\nEnter the string : ");
     scanf("%s",str);
     for(i=0;i<strlen(str);i++)
       for(j=0;j<strlen(str);j++)
         if(str[i]<str[j])
         {
           temp = str[i];
           str[i] = str[j];
           str[j] = temp;
         }
     printf("\nReversed String is : [ %s ]\n",str);

     return 0;
  }

OUTPUT : :


/*  C Program to Sort a String in Alphabetical order  */

Enter the string : codezclub

Reversed String is : [ bccdelouz ]

Process returned 0

Above is the source code for C Program to Sort a String in Alphabetical order which is successfully compiled and run on Windows System.The Output of the program is shown above .

In the second loop j should start from i+1 instead of 0
