Before talking about function call and return value problem, let's look at the problem of memory allocation in C + +. The C + + compiler divides computer memory into code areas and data areas, and it is clear that the code area is where the program code is stored, and the data area is the variables and constants that appear in the process of compiling and executing the program. The data area is divided into static data area, Dynamic Data area and constant area, and dynamic Data area includ

Init is one of the most indispensable programs in Linux system operation. Init process, which is a user-level process initiated by the kernel. The kernel will find it in several places in the past that used Init, and its correct location (for Linux systems) is/sbin/init. If the kernel cannot find Init, it will try to run/bin/sh, and if it fails, the boot of the system will fail.Linux 7 RunLevel (0: shutdown, shutdown mode,1: single-user mode,

Saturday.W 7 days a week number for 0 (Sunday) to 6 (Saturday)N iso-8601 a 7-day week of digital representation. 1 expression Monday (Monday) to 7 means Sunday (Sunday)W iso-8601 the number of weeks in a year. Counted weekly from Monday onwards. So there are 01-53, the order is marked for 53 weeks. DayD, with two digits beginning with 0, represents the day of one months. For example, 01 to 31J is the same as D, except that it doesn't start with 0. F

Sorting problem Description: Often encountered in the development of the "1-2", "1-15" or "1.2", "1.15" data fields to sort, and such a field can not be directly by the way of ordering by.

Step one: Do not recommend using the system's own sound card driver 1. If you install a system that uses the system's own sound, it may be that the sound is too old to use the microphone. 2. If you do use a system sound driver to drive, we can download a "Driver Wizard" to update your sound card driver. 3. The installation of sound card driver does not solve the microphone problem, but we will be in th
