removing a character from a char array

[cxs00u]

hi,

I was wondering how I could look through a char array and remove any white space characters I found. eg if I a had a char array of

char buffer[] = "hell o";

I could modify it to "hello";

can anyone help

Thank you

[Prelude]

char a[] = "Hell o",
     b[10] = {0};
for ( int x = 0, y = 0; a[x] != '\0'; x++ )
  if ( !isspace ( a[x] ) b[y++] = a[x];

Didn't you ask this already?

Well to do it in a more practical sense, why not just monitor what is put in the array (whether it is through user input or whatever):

while( (c = cin.get()) != '\n')
{
   switch( c )
   {
      case ' ':       // If it is a space
         break;
      default:
         array[i++] = c;
         break;
    }
}

Another way is to use the isspace() function in ctype.h with an if-else tree.

If you want to just go through an array and delete spaces, it is just searching and shifting. I think you should be able to figure out the code for it. Here' s the pseudo anyway:

for i = 0 to ArrayLength
if you find a space then shift everything after it up one

Good luck
