Help needed

I have written this code to swap the characters between the asterisks when a * is detected however it does not seem to work. Anyone? Take for example an input string "This is *swaped* here no change" will produce an output string " This is *depaws* here no change". Thanks.

Code:

 
#include <vcl.h>
#include "MT262io.h"
#pragma hdrstop
//---------------------------------------------------------------------------

#pragma argsused
int main(int argc, char* argv[])
{
// Any declarations you require go here.
AnsiString Sentence,Sentence1,Sentence2;
int index,index1,Endindex;
bool swap;

// Your code goes here.
index=1,index1=1,Endindex=1;
swap=true;

Sentence=ReadStringPr("Enter text to be tested.");

while(index<=Length(Sentence))
{
        if(swap==false)
        {
        Sentence1[index]=Sentence[index];
        index=index+1;
        }
        if(Sentence[index]=='*')
        {
        while(Sentence[index1]!='*')
        {
        index1=index1+1;
        }
        swap=true;
        }
        if(swap==true)
        {
        for(index=1; index<=10; index++)
        {
        Sentence[index]=Sentence2[Endindex];
        Endindex=Endindex-1;
        }
        swap=false;
        }
        }
        WriteString(Sentence1);
        WriteString(Sentence);
        Sentence.Insert(Sentence2,'*'+1);
  getchar();
  return 0;

For loop babe.

Cycle through each character in an array, checking if that element == '*' .

Try indenting the code better as well. Good indentation tells you a lot about how the code is behaving without having to do a lot of thinking about what every line is doing.

Code:

        if(swap==false)
        {
        Sentence1[index]=Sentence[index];
        index=index+1;
        }
// would be changed to
        if(swap==false)
        {
                Sentence1[index]=Sentence[index];
                index=index+1;
        }

Also, start simple!.

Your first attempt at this code should be something to identify the *'s
Like

Code:

while(index<=Length(Sentence)) {
    if ( Sentence[index]=='*' ) {
    } else {
    }
}

The 'if' part would then toggle your 'swap' flag between true and false say.
