Int main () and void main () are both normal. Which one should we use? In fact, the two can be used in most compilers. Which one should we use? Can both be used at will? Should be used IntMain (){Return 0;} This complies with ANSI standards and can be used in future development. Return 0 tells the Operating SystemProgramRun successfully.

function of the return value The return value of the main function is used to describe the exit state of the program. If 0 is returned, the program exits normally, and the meaning of the other numbers is determined by the system. Typically, the return of a non-0 represents a program exception exit. Below we do a small experiment in the WinXP environment. First compile the following program:int main (void){

Main () function, presumably everyone is not strange, from the beginning of the program, we began to write main (), we all know that main is the entrance of the program. That main as a function, and who calls it, how it is called, returned to whom, what is returned? This time, let's talk about the problem.1. Form of th

In C and C + + is different, we know that C language is more relaxed, flexible, and C + + goal is to change the C language more relaxed characteristics, the implementation of a more rigorous approach, including strict type checking and so on. In fact, in the C language, the main function can be called recursively, while in the C + + standard, the main function cannot be called recursively. recursive invocat

Why the Java Main method must be static Look at the type of information today to find a problem, you can not print this keyword in the main method information, then remember the previous knowledge, can not call this in the static method. The reason is simple, this means "this object", which is the object that declares a class, whereas a static method does not belong to a particular object but belongs to th

Many people even some books on the market use void main (), in fact, this is wrong. void Main () has never been defined in C + +. C + + Father Bjarne Stroustrup explicitly in the FAQ on his home page that the definition void main () {/* ... */} is not and never has been C + +, nor ha s it even been c. (void Main () nev

The previous article wrote the address translation of the virtual memory and main storage, so now write the address image of the cache and main memory. I will use my own understanding and an example of how to speak clearly. First, the address image is the main memory address space in a way to image to the cache, that is, the
