First, the understanding of the destructor functionThe constructor of the class is described in my previous blog post. http://www.cnblogs.com/MrListening/p/5557114.html.here, let's briefly talk about the destructor of a class, which is a member function of a class whose name consists of a tilde plus a class name. Look at its name, we'll probably think of him. function, which is to perform the opposite of the constructor: disposes the resource used by the object and destroys the non-static member

Recognition of destructor Here we will briefly talk about the class destructor, which is a member function of the class. The name consists of the wave number and the class name. Looking at its name, we can probably think of its function. It is to execute the opposite operation of the constructor: release the resources used by the object and destroy non-static members.

user group originally attempted to re-reconcile and integrate the differences between the call interfaces of ATT's System V and Berkeley CSRG's BSD system, thus generating the/usr/group standard in 1984. In 1985, IEEE Technical Committee standards Subcommittee TCOS-SS began to instruct the IEEE Standards Committee with ANSI support to develop formal standards for program source code portability of operating system service interfaces. In April 1986, IEEE developed a trial standard. The first for

standard. From the 1970 to the 80 's,C language was widely used, from mainframe to small microcomputer, also derived from the C language of many different versions. In 1983, the American National Standards Association (ANSI) established a committee X3J11 to develop the C language standard. In 1989, the American National Standards Association (ANSI) passed the C language standard, known as ANSI x3.159-1989 "Programming Language C". Because this standard is passed in 1989, so the general abbrevia
