Declaration
Hi all... I am declaring an integer like:
int i=012;
When I am printing this value of i, it is printing 10. Why so ?
because the 0 is meaningless in this case.
it will work if you declare as STRING ...
well actually not so sure
When you declare an integer, and the leading digit is a '0', the compiler considers the value to be an Octal representation of the number. So, in your case, it is reading in 12 base 8.
When you print it out, it converts it to decimal. so you get 1*8 + 2*1 or 10.
you can tell octal numbers because they have the preceding 0
so in your case:
int i = 012;
this is how it is represented:
the 0 tells you its octal,
the 1 tells you how many 8's there are, in this case only one,
the 2 tells you how many 1's there are, in this case 2,
so (8*1) + (1*2)= 10
hope this helps.
