Sorry if its a bit out of place but I’m hoping there is someone here that knows the answer.
I’m writing a .NET Console Application in C# that when the user inputs a credit card number it will output what type the credit card is.
The problem I have is declaring the variable that holds the credit card number and that I don’t know what data type it is? Is it a string, a ulong or do I have to create an array of characters?
Thanks in advance.
