Hey grav, all I get is 0''s

change:
printf("%c", string);
to:
printf("%c", string);//<-page changes it to italics tag<br><br><br>and grav…gets() doesnt add a '\0' character? (asking)<br><br><SPAN CLASS=editedby>[edited by - kordova &#111;n March 4, 2003 9:10:58 PM]</SPAN>

gets() does set a ''\0'' on the end and I believe its fgets that doesnt do that. So thats why I set a NULL value to the end, so that wasnt necessary.

If string[strlen(string)+ 1] = ''\0''; is taken out the for loop gets changed to

for(i=strlen(string);i>-1;i--)

When it added a space to the beginning that should have told me I didnt need to add the ''\0'' I was just too lazy to find out why it did it. Stupid mistake on my part.

Awsome guys, thanks. How would I go about changing the inversed string into integers? I also can't get it to work properly when I try to type in that number into my other .cpp file (the decoder). Thanks.

Did you have a question in that last post? I compiled that code you just posted and it seems to work unless you want it to do something other than display the character that the input number represents.

Yeah I had one... There''s actually two parts to this:

In scramble.cpp

You know how I wanted to know how to reverse a string and all? Well, what I''m tring to do, is once that is reversed, I want to turn the character values of that reversed string into their integer values (With the integers representing the appropriate characters).

In descramble.cpp

I want to do the exact opposite. (Turning the integers back into the reversed string, and then reverse the string again so it is readible).

I actually have two questions now:

1) How do I turn the reversed string into the appropriate integer values?

and...

2) How do I create the syntax in "descramble.cpp"? (I know sort of the basis syntax, but get stupid little errors all the time).

#include <stdio.h>#include <string.h>// Global variable so you can use it in other functions// *NOTE this holds 80 integers    int num[80];   // Same size of array int main( void ){	char string[80];	char *ptr;	int i;	printf("Enter a string:\n");	gets(string);	for(i=(strlen(string) -1);i>-1;i--){    printf("%c", string);    num = string<br>}<br>printf("\n");<br>// This loops through again and sends it back <br>// using num[] in foward order<br>for(i=0;i<(strlen(string));i++)<br>    printf("%c", num);<br>printf("\n");<br><br>return 0;<br>}<br> </pre> <br><br>As far as your syntax problem…send what code you have and ill help you from there.    </i>   

I keep posting bad code....
for(i=(strlen(string) -1);i>-1;i--)
should be
for(i=strlen(string);i>-1;i--)

and you dont need char *ptr;

That wouldnt work because an array cant be = to an array.

This is true, but the AP wasn''t copying arrays. He was copying specific characters in each array, which is perfectly fine. I tested his code, and it didn''t work, but it only needs a little improvement.

strcpy has to be used to copy an array but in thatcase I dont think it will let you copy a single character of the array. I think when you did out[j] = in; would mean that that one character of the string out would be set to the entire string of in rather than the right character. I did something about what you did except I just used one variable and it works fine.

Sorry, you''re wrong. You haven''t been programming for very long, have you? I don''t mean to offend you, but be more careful when you dispense advice.

Look up atoi() in the MSDN.
