I am very new in C++ so I don't have much of knowledge about the language. The question is I have promoted my new program to enter 12 characters. So, now I want to check if the user have entered 12 characters exactly not less and not more. The code will include some numbers with some letters EX ( 345D3CC123FA ). How I can do that ? I know that I am going to use If statement but in the condition EX ( if ( my condition) ) I don't know how to tell the check if the user entered 12 characters or not... I hope it is clear..
