best way to read string

[cppdotnet]

I have this number from which I have to read first few number depending on another number. What is the best way to do that. For example ... NumToread = 3 , number = "4567889465" answer should newNum = 456 i can do that using for (int i=1;i<=NumToread ;i++) does any one knows better way ... As you can say .. I am very new to programming Thanks CPP Thanks

You should use the String.Substring() method. int numToRead = 3; string buf = "123456789"; buf = buf.Substring(0, 3); // buf now = "123"
