C Program to Sort Elements in Lexicographical Order (Dictionary Order)

To understand this example, you should have knowledge of following C programming topics:

This program takes 10 words from user and sorts elements in lexicographical order. To perform this task, two dimensional string is used.

Source Code to Sort Words in Dictionary Order

#include<stdio.h>
#include <string.h>
int main(){
    int i,j;
    char str[10][50],temp[50];
    printf("Enter 10 words:\n");
    for(i=0;i<10;++i)
        gets(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("In lexicographical order: \n");
    for(i=0;i<10;++i){
       puts(str[i]);
    }
return 0;
}

Output

Enter 10 words:
fortran
java
perl
python
php
javascript
c 
cpp
ruby
csharp

In lexicographical order:
c
cpp
csharp
fortran
java
javascript
