Abhishek Mazumder , normally variables do need to be declared or initialized. But in your case you are using somethin like this: x*=n-(r-(r-i)) so this means the same as: x = x * n-(r-(r-i)). this will assign the right side expression to x. When x is not declared, this creates an error, because x is also in the expression on the right side.

Means that you reffer to the x variable before it is assigned In your case it is never assigned

Abhishek Mazumder, x=x*(n-(r-(r-i) Can only be done if x already has a value While asigning a variable you cant use its own name in its value
