I got the information below from a training/video site I subscribe to. Why would they make a language harder to understand than is needed? What is the reason for having "++" to add 1 and "+=" to add 10? Why not just i+1 or i+10? Doesn't make sense to me. And, this actually is C#, not C++, but I didn't see a C# forum. Unless they are the same?

int i = 0;
// convert from a string
int i = int.Parse("1");
// convert froma string and don’t throw exceptions
if (int.TryParse("1", out i)) {}
i++; // increment by one
i--; // decrement by one
i += 10; // add 10
i -= 10; // subtract 10
i *= 10; // multiply by 10
i /= 10; // divide by 10
