Sort strings Lexicographically

Write a C Program to Sort strings Lexicographically (Dictionary Order). Here’s simple C Program to Sort strings Lexicographically (Dictionary 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 strings Lexicographically (Dictionary 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 strings Lexicographically (Dictionary Order)  */

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

int main()
{
    int i, j;
    char str[10][50], temp[50];

    printf("\nEnter 10 words:: \n");

    for(i=0; i<10; ++i)
        scanf("%s[^\n]",str[i]);


    for(i=0; i<9; ++i)
        for(j=i+1; j<10 ; ++j)
        {
            if(strcmp(str[i], str[j])>0)
            {
                strcpy(temp, str[i]);
                strcpy(str[i], str[j]);
                strcpy(str[j], temp);
            }
        }

    printf("\nIn lexicographical order: \n");
    for(i=0; i<10; ++i)
    {
        puts(str[i]);
    }

    return 0;
}

OUTPUT : :

/*  C Program to Sort strings Lexicographically (Dictionary Order)  */

Enter 10 words::
aba
sbd
snd
fjd
aas
ase
das
das
csd
eds

In lexicographical order:
aas
aba
ase
csd
das
das
eds
fjd
sbd
snd

Process returned 0
