Program to arrange 2d string in Dictionary order.

Solution:

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

void main()
{
    char s[3][10];
   char s1[20];
    int i,j;

    for(i=0;i<3;i++)
    {
        printf("Enter string: ");
        gets(s[i]);
    }
    
     printf("Strings are: ");
    for(i=0;i<3;i++)
    {
        puts(s[i]);
    }

    for(i=0;i<3;i++)
      {
          for(j=i+1;j<3;j++){
          if((strcmp(s[i],s[j])) == 1)//comparing the strings if strcmp return 1 then, 
          {                           //we are swapping the both string
              strcpy(s1,s[i]);
              strcpy(s[i],s[j]);
              strcpy(s[j],s1);
          }
      }
      }

      printf("String in dictionary order are: ");
      for(i=0;i<3;i++)
    {
        puts(s[i]);
    }
}

defining a function 'to_dictionary' which will arrange strings in dictionary order

void to_dictionary(char s[3][10])

{     char s1[20];
int i,j;
      for(i=0;i<3;i++)
      {
          for(j=i+1;j<3;j++){
          if((strcmp(s[i],s[j])) == 1)
          {
              strcpy(s1,s[i]);
              strcpy(s[i],s[j]);
              strcpy(s[j],s1);
          }
      }
      }
}

Using above define function 'to_dictionary()':

void main()
{
    char s[3][10] = {"Tester","programmer","Analysis"};

    to_dictionary(s);
    printf("String in dictionary order are: ");
    for(int i=0;i<3;i++)
    {
        puts(s[i]);
    }
}

Output1

String in dictionary order are:  Analysis   programming   Testing

Using above define function 'to_dictionary()':

void main()
{
    char s[3][10] = {"ziva","laptop","computer"};

   to_dictionary(s);
    printf("String in dictionary order are: ");
    for(int i=0;i<3;i++)
    {
        puts(s[i]);
    }
}

Output2

String in dictionary order are: Annie   Ryan   Zack

Using above define function 'to_dictionary()':

void main()
{
    char s[3][10] = {"ziva","laptop","computer"};

    to_dictionary(s);
    printf("String in dictionary order are: ");
    for(int i=0;i<3;i++)
    {
        puts(s[i]);
    }
}

Output3

String in dictionary order are: English   Maths   Science
