C Programming: Sorts the strings of an array using bubble sort

C String: Exercise-12 with Solution

Write a program in C to read a string through keyboard and sort it using bubble sort.

C Programming: Sorts the strings of an array using bubble sort

Sample Solution:

C Code:

#include <stdio.h>
#include <string.h>
void main()
{
  char name[25][50],temp[25];
  int n,i,j;
  
       printf("\n\nSorts the strings of an array using bubble sort :\n");
       printf("-----------------------------------------------------\n");  
  
 
  printf("Input number of strings :");
  scanf("%d",&n);

printf("Input string %d :\n",n);
  for(i=0;i<=n;i++)
  {
       
       fgets(name[i], sizeof name, stdin);
  }
     /*Logic Bubble Sort*/

     for(i=1;i<=n;i++)
	for(j=0;j<=n-i;j++)
	  if(strcmp(name[j],name[j+1])>0)
	  { 
            strcpy(temp,name[j]);
	    strcpy(name[j],name[j+1]);
	    strcpy(name[j+1],temp);
	  }
   printf("The strings appears after sorting :\n");
	      for(i=0;i<=n;i++)
		 printf("%s\n",name[i]);
 
} 

Sample Output:

Sorts the strings of an array using bubble sort :

The strings appears after sorting :                                                                           
                                                                                                       
one
