    Unhappy Sorting paragraphs the other way around

    Hi!!
    I have to make a program which will be sorting paragraphs backwards
    like from this
    SOME TEXT
    SOME MORE TEXT
    A HELL LOT MORE OF SOME TEXT WITH TEXT ON TOP OF THE TEXT BEHIND THE TEXT A LOT OF TEXT

    to this

    A HELL LOT MORE OF SOME TEXT WITH TEXT ON TOP OF THE TEXT BEHIND THE TEXT A LOT OF TEXT
    SOME MORE TEXT
    SOME TEXT


    in other words the program finds the \t tab character then reads till the \n character and thats the first paragraph then writes the second paragraph in front the first one and so on till the are no Paragraphs to proccess

    Any ideas? (some code would be nice too)
    thnx.

    Sure, I have an idea. You are lazy.

    Now read the rules - may as well read this too. Then you can put some effort into writing a program, and then if it still does not work, come back here and post your *best* attempt. It would be at that point where someone might want to help you.

    thnx...

    I would swear that says make a program, not request a program from someone.

    Alright what you want to do is read a string(paragraph) into an array index, then increase the index, and repeat until you read the whole file. Then you want to output the array in reverse index.

    That's my two cents and don't ask me to borrow a dollar.
    ...and let me add I'm not the best programmer, so if you ask for a dollar, I might give it in foreign currency.

    'some' effort

    Code:
    #include <stdio.h>
    #include <stdlib.h>
    void read_file ();
    void show_file ();
    void mix();
    FILE *input, *output;
    int d;
    char *line;
    
    main ()
    {
    	if ((input=fopen("test.txt","r"))!=NULL)
    	{
    		read_file();			
    		mix();
    	        int i;
                    for (i=0;i<d;i++)
    		printf ("%c", line[i]);
             }
    	else
    		printf ("File test.txt not found\n");
            printf ("\n");
            system("PAUSE");	
     
    }
    
    void read_file ()
    {
    	int i;
    	d=0;
    	
        while (!feof(input))
    	{
               fgetc(input);
    		   d++;
    	}
    	d--;
    	rewind(input);
    	line=(char*)malloc(sizeof(int)*d);
    	for (i=0;i<d;i++)
    	{
    		line[i]=fgetc(input);
    	}
    	fclose(input);
    	show_file();
    }
    
    void show_file ()
    {
    
    int i;
    		for (i=0;i<d;i++)
    		
    			printf ("%c", line[i]);
    
    }
    
    void mix()
    {
    	int a,i;
        output=fopen("output.txt","w");
      
        for(i=0;i<d;i++)
    	{
        	for(a=0;a<d;a++)
    	    {	
    //OOAI - OUT OF ANY IDEAS
                }
    	
        a=0;
    	}
    fclose(output);
    }

    How about an unsorted doubly linked list to do your paragraph swapping?

    You shouldn't cast malloc().

    This part of main()
    Code:
                    for (i=0;i<d;i++)
    		printf ("%c", line[i]);
    looks like a job for show_file().
