    debugging code

    hi, first of all, i would like to congratulate u all guys for this beautifull board! looks pretty nice u know...
    Im a very loyal member of all boards, so, from now on, ull see me around lotz of times.
    My native language is Spanish, but i can handdle my english in a good way...i hope u can understand me.


    ok, now, im making a proyect, but i get an error in a line of my code, not when compiling, but when running... the idea of this code is to write a mesagge in an array, then, transfer it into a matrix, and once again, pass it to an other array, colum by colum, but in a very nice way... heres my code, please help me..


    OH, by the way, i havent learnded to use poiters, so please dont use any, thanx

    Hi DS.

    I could not even compile the code, I am using Dev c++.

    You do not have a return statement for yout main() function.
    Also your main() function should be 'int main()' (not necessary on all compilers though.

    I corrected these errors but I could still couldn't get it to compile...
    I will have another look later when I've got more time.

    i have noticed that my borland code wont compile in Dev, i think its because Dev uses some odd syntax rules.

    Run time errors can be caused by many factors, if it is an array make sure it is not overflowing ((ie if its an 8 bit array, make sure your not entering 12 bits - it will cause an RTE)

    To prevent these try validating the string length, i wll have a look at the code and see if i can compile it in Borland
