Hi, I'm some what new to programming, so chances are this was an easy question, but I could find an answer anywhere else. I was looking through code by somebody else, and I noticed that they sometimes put letters in with their ints. For example
private int someInt = 0x2a;
What does the 'x' and the 'a' mean?
Hi,
0x means we are talking in hexadecimal or base 16
Hexadecimal numbers are:-
1 2 3 4 5 6 7 8 9 A B C D E F
So 0x2a means hexadecimal of 2a
The "a" means 10 in hexadecimal and the 2 means (2X16) which equals 32
Therefore 32 + 10 equals 42 in hexadecimal
Maybe this will explain it better:-
