Can someone tell me how to get single characters from a string to a char array. This book by deitel is driving me crazy. Its asking for a struct but the book doesnt use one. It has to be in .NET .
void EnterName(){
String ^x;
String ^tmp, ^y;
	Console::WriteLine("Enter your name: ");
	
	x = (Console::ReadLine());
	for(int i = x->Length; i > 0; i--){
		y =  String::Concat(tmp,x->Chars[i].ToString());}
		
		Console::WriteLine(" {0}",y);
}



Error	1	error C3293: 'Chars': use 'default' to access the default property (indexer) for class 'System::String'	c:\Documents and Settings\posti\Desktop\String Assignment\String\String\String.cpp	15	
Error	2	error C2228: left of '.ToString' must have class/struct/union	c:\Documents and Settings\posti\Desktop\String Assignment\String\String\String.cpp	15

the error tells you, you should use indexing to get the character from the Chars property

in code:

x[i]

returns a character at position i


another thing:
in the for loop, you start at i=x->Length
note that indexing starts at 0 and ends at Length-1, so you're trying to get a character beyond the length of the string.

thank you that worked, the stuff from before is right out of a book, I have to stop buying cheap drugs...


void EnterName(){
String ^x;
String ^tmp, ^y;
int counter = 0;
Console::WriteLine("Enter your name: ");

x = (Console::ReadLine());
Console::WriteLine(" size {0}", x->Length);
for(int i = x->Length; i > 0; i--){

Console::Write("{0}", y = String::Concat(tmp,x[counter].ToString()));
counter++;}

Console::WriteLine(" The result:{0}",x);
}
