Hi can someone help me understand what this function does exactly?
I know if(isspace(*src)) checks for whitespace in the array but I'm unsure what everything else does/means.
I'm guessing while(isspace(*(src+1))) deletes each whitespace too?

void modifyspace(char *dest, char *src)
{
   for( ; *src; dest++, src++)
   {
      *dest = *src;
      if(isspace(*src))

            while(isspace(*(src+1)))
               src++;
   }

   *dest = '\0';
}

It looks to be copying the characters from *src to *dest, it is replacing multiple white space characters with one space character.

Have you considered running some tests?

char test[] = "this is   a       test";
char result[100];
printf("Before=%s\n", test);
modifyspace(result, test);
printf("After=%s\n", result);
