Remove extra blanks from a string

[afr02hrs]

Hi Experts

I am trying to get the following program running correctly. I would like to be able to input a line of text containing multiple space characters between words and have the program remove any number of excess space characters so that the sentence is rewritten correctly containing only 1 space character between individual words. However this program outputs each word on a separate line! Is there a problem with my loop?

Many thanks

int main(int argc, char **argv)
{
 AnsiString Line;
 int Index;
 
Line = ReadStringPr("Enter your text. It must not finish with a space character." );
Index = 1;
//read each char of Line
 
while (Index <= Length(Line))
{
   //if current char is not a space
   if (Line[Index] != ' ')//;
      {
      //write current char to screen
      WriteChar(Line[Index]);
      Index = Index + 1;
      }
   else //if current char is a space
      {
            WriteStringCr(' ');
      }
      //ignore all consecutive spaces
      while (Line[Index] == ' ')//;  this semicolon may have created an infinite loop not allowing anything to print to screen
        Index = Index + 1;
 
} 
 getchar();  // to keep the display on until you press Enter key
 return 0;
 }

have you a } in the wrong place?

else //if current char is a space
{
WriteStringCr(' ');
}  <<< should this
//ignore all consecutive spaces
while (Line[Index] == ' ')//; this semicolon may have created an infinite loop not allowing anything to print to screen
Index = Index + 1;
<<  be here????

Unfortunately moving this brace does not change anything. The words are still written one on each line and not as a corrected sentence. Braces seem to be the root of all evils!!

What is the difference between WriteChar() and WriteStringCr() ? Does one of them always output a newline character after execution?
