Int flag_of_zero
WebFor the sake of argument, let's say I'm working with an 8-bit integer that is part of a larger struct and is being used to store 8 flags. There are a little over 25 million of these structs, so packing the flags into an integer is saving about 175mb of RAM. Consider the following scenario: you have 3 flags packed into the integer. WebThere are three kinds of flags which are status flags, control flags and system flags. Status flags are as follows: CF: Carry Flag. PF: Parity Flag. AF: Adjust Flag. ZF: Zero Flag. SF: Sign Flag. OF: Overflow Flag. The carry flag is set when a math operation on an unsigned integer value generates a carry or borrow for the most significant bit.

WebFor integer specifiers (d, i, o, u, x, X): precision specifies the minimum number of digits to be written. If the value to be written is shorter than this number, the result is padded with leading zeros. The value is not truncated even if the result is longer.
