How do you make an if statment to several things?

[mercedesbenz]

I'm making a program and want to use an if statement to add a 0 to output if the numbers = 0-9. I know how to do an if statement like:

int number=0;
if (number==5){
cout << " whatever " << endl;
}
Is there any way to do somthing like this?

int number=0;
if (number==1-9){
cout << " whatever " endl;
Thankyou for the help, it is well apreciated!

Use a compound conditional like this:

if(number >0 && number < 10)

Logical AND - &&, Logical OR - ||, Logical Inversion - !

Some things you should get comfortable with.
