What does computer main mean?
Jan 19, 2021 pm 02:57 PM
Computer main represents the main menu or main category in computer software. Some desktop software will have a main menu, including basic operation menus, named main; and in high-level languages such as development languages java and c language, there will be a main class, which is the entrance to program execution. A program can have multiple functions, but there can only be one main() function.

What is the use of main function in Java
May 04, 2023 am 09:34 AM
The general way of writing the main function is as follows: publicstaticvoidmain(String[]args){…} The functions of these keywords are explained below: (1) public keyword, this is easy to understand. Declaring the main function as public tells other classes that they can access this function. (2) The static keyword tells the compiler that the main function is a static function. That is to say, the code in the main function is stored in the static storage area, that is, this code already exists after the class is defined. If the main() method does not use the static modifier, then there will be no error in compilation, but if you try to execute the program, an error will be reported, prompting
What is the reason why Python does not have a main function?
Apr 19, 2023 am 10:01 AM
Why must main function be forced as the entry point? These languages are compiled languages, which require the code to be compiled into executable binaries. In order for the operating system/bootloader to find the beginning of the program, such a function needs to be defined. In short, you need to define a crucial beginning in a large amount of executable code. It is not difficult to see that for these languages, the main function is an indispensable component. However, when we turn our attention to Python, we will find that the situation is very different. Python is an interpreted language, a scripting language. The running process is performed from top to bottom, line by line, which means that its starting point is known. Each .py file is an executable file and can be used as the entry file for the entire program, meaning
How to use the main method in Python
May 05, 2023 pm 01:25 PM
The beginning of the text ifname=="main": can be regarded as the entrance of the Python program, just like the main() method in Java, but it is not completely correct. In fact, the Python program is run line by line from top to bottom. In the .py file, the code except the functions defined after def will be considered as the contents of the "main" method and executed from top to bottom. If you just want to write a great "helloworld" and don't want to write a function, you can just print('helloworld'). This is a "program" and does not require the so-called "main" method.
What is computer main
Aug 15, 2023 pm 05:31 PM
Computer main means main function. In programming languages such as C, C++, and Java, the main function is the entry point of the program. When running a program, the operating system will first call the main function, which can define the logic and algorithm of the program and interact with it. When users interact, it is the starting point for program execution and the control center of the program.
