In C language, do octal and hexadecimal in integer constants have signed numbers? Why is there a decimal system?
Usually, some computers store the highest sign bit. If octal 0 1234 is positive and octal 0 123456 is negative, then the machine should be a 16 bit machine, because octal 0 1234 binary bit is1010000. Octal 0 123456 binary is101kloc-0/011165438, and the highest value of the former is (No.
