Thread: Deleting spaces in a string

Hi,
I want to write a code which takes an array of 20 characters and deletes all spaces between characters, it should leave only letters. For example:
input :a b c d e
I want to make it : abcde

I wrote this code, but it didn't change anything:

Code:

#include <stdio.h>

 int main ()
 {
         int i;
         char a[21];



         gets(a);

         for(i = 0; i < 20; i++)
         {
                 if(a[i] == 8 || a[i] == 9)
                 {a[i]= a[i+1];
                 i--;}
                 else continue;
         }

         printf("%s", a);
         printf("\n");

         return 0;
 }

Can you help me with that? Thanks...

your searching if a[i]==8 or 9 whish is back space or horiztal tab then you making i+1 to that a and minunsing i after that ii dunno why your doing that anyways ?
why dont you try copy anything inside the string thats not space
if(a[i]!=' '){continue your function here}?

Code:

if(a[i] == 8 || a[i] == 9) /* what is this statement supposed to do??? */

to catch if the character is a space or not (backspace and horizontal tab)

Then use the character constant instead of its decimal value which depends on the underlying character set.

I solved this problem in another way thanks, and I asked at first at daniweb but i couldn't get the answer for hours, then I asked here..
