Thread: Find Error in my Code(Sorting Strings)

I want to stop repetition and print a word only once..

Code:

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


int main()
{
    printf("\n\t\t\tSorting Strings\n");
    int x = -1,m;
    char str[100][100],temp[100];
    FILE * in = fopen("input.txt","r");
    do{
        fscanf(in,"%s",str[++x]);
    }while(strcmp(str[x],"end")!=0);


    for(int i=0;strcmp(str[i],"end")!=0;i++)
               strlwr(str[i]);


 for(int i=0;strcmp(str[i],"end")!=0;i++)
    {
        for(m=i-1;m>=0;m--)
        {
        if(str[i]==str[m])
                   break;
        }
        if(str[i]==str[m] && m>=0)
                   continue;


    for(int j=i+1;strcmp(str[j],"end")!=0;j++)
        {
            if(strcmp(str[i],str[j])==1)
            {
                strcpy(temp,str[i]);
                strcpy(str[i],str[j]);
                strcpy(str[j],temp);
            }
        }
        printf("\n\t%s",str[i]);
    }
    printf("\n\n");
    return 0;
}

Input:
f you can dream and not make dreams your master
If you can think and not make thoughts your aim
If you can meet with Triumph and Disaster
And treat those two imposters just the same
If you can fill the unforgiving minute
With sixty seconds worth of distance run
Yours is the Earth end

Code:

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


int removedups(char str[100][100],int num)
{
   for(int i=0;str[i][0]!='\0';i++)
   {    if(str[i]==str[i+1])
   {
       strcpy(str[i+1]," ");
       --num;
   }
   }
   return num;
}


void printwords(char str[100][100],int num)
{
    for(int i=0;i<num;i++)
        printf("\n%s",str[i]);
}


int readfile(char str[100][100], const char *filename) {
    FILE * in = fopen(filename,"r");
    int n = 0;
    while ( fscanf(in,"%s",str[n]) == 1 ) {
        n++;
    }
    fclose(in);
    return n;
}


void lowercase(char str[100][100], int numwords ) {
    for(int i=0;i < numwords;i++)
               strlwr(str[i]);
}


void sortwords(char str[100][100], int numwords ) {
  for ( int i = 0 ; i < numwords ; i++ ) {
    for(int j=i+1;j < numwords ;j++)
        {
            if(strcmp(str[i],str[j])>0) // it's not specifically == 1
            {
                char temp[100];
                strcpy(temp,str[i]);
                strcpy(str[i],str[j]);
                strcpy(str[j],temp);
            }
        }
    }
  }




int main()
{
    printf("\n\t\t\tSorting Strings\n");
    char str[100][100];


    int numwords = readfile(str,"input.txt");
    // printwords(str, numwords); // use this to make sure the file read OK


    lowercase(str, numwords);
    // printwords(str, numwords); // use this to check ...


    sortwords(str, numwords);
    // printwords(str, numwords); // use this to check ...


    numwords = removedups(str, numwords);


    printwords(str, numwords);
    return 0;
}
