What is caused by leading 0

Question

14/2 = 7
014/2= 6
can someone please explain what happens? thank you

Answer 1

14 is decimal while 014 is octal, which is 12 in decimal.
"To use octal notation, precede the number with a 0 (zero). To use hexadecimal notation precede the number with 0x. To use binary notation precede the number with 0b."
