// input words
for(i=0;i<4;i++)
{
scanf("%s",&words[i]);
}
// iterate from 0th intex to 3rd index
for(i=0;i<4;i++)
{
// now iterate from (i+1)th index to 3rd index
for(j=i+1;j<4;j++)
{
// if the ith word is greater than the jth word then swap
if(strcmp(words[i],words[j])>0)
{
strcpy(temp,words[i]);
strcpy(words[i],words[j]);
strcpy(words[j],temp);
}
}
}
// print the words
for(i=0;i<4;i++)
{
printf("%s\n",words[i]);
}
return 0;
