    Question

    I wrote a program that deletes the TDS EXE and OBJ of a file.
    (I do this because I compile so many programs and I delete them
    and keep only the .C or .CPP files)

    so I wrote another program, called it DUMP. It takes command
    line args. For example, if i want to delete all files (OBJ TDS EXE)
    of DRAGONWAR.CPP, I will simply type DUMP DRAGONWAR
    and it will delete OBJ TDS EXE of DRAGONWAR file.

    Here's the code:
    Code:
    #include <stdio.h>
    #include <stdlib.h>
    #include <string.h>
    
    main(int argc, char *argv[])
    {
    	char one[20] = "DEL " ;
    	char two[20] = "DEL ";
    	char three[20] = "DEL ";
    
    
    	strcat(one, argv[1]);
    	strcat(one, ".tds");
    
    	strcat(two, argv[1]);
    	strcat(two, ".exe");
    
    	strcat(three, argv[1]);
    	strcat(three, ".obj");
    
    	printf("%s\n%s\n%s\n", one, two, three);
    
    	system(one);
    	system(two);
    	system(three);
    
    	
    }
    My problem is that this code is not always working. What could
    the reason be?

    >> My problem is that this code is not always working

    So when it doesn't work, what's the problem.

    Perhaps it could be because of long filenames. Try enclosing the filename in inverted commas.

    oh

    when it doesn't work,

    it simply says

    File Not Found
    File Not Found
    File Not Found

    The files will be manually deleted one by one later by me
    (Thought of using this small program to do that for me)

    Long filenames.... hmm, i am going to test that right away,
    I will compile some programs and delete them and see
    if it is true.

    [edit]
    Yes, it is with the long filenames. I just experimented with
    several files and you're right.
    [/edit]
    Another question: if i send the argument in "", does it
    affect any of my code ?

    Try testing it. I don't think it will affect anything besides the fact that your array would be 2 chars bigger.

    You should be using the absolute path instead. Like:
    Code:
    strcat(one, "C:\\dir\\");
    strcat(one, argv[1]);
    strcat(one, ".tds");
    ...
    And ofcourse, watch out for buffer overflow!

    nope

    nope

    It is sometimes working with "" but sometimes not (same error.
    file not found)

    >You should be using the absolute path instead.
    How do i get the current dir ?
