Label:The use of PL/SQL enables modular programming . In a PL/SQL block, you can define several sub-programs . Code that is relatively independent and needs to be executed frequently is defined as a subroutine that is called according to the name of the subroutine when needed.This not only facilitates the programming and coding, but also facilitates the debugging of the program.PL/SQL has two forms of subro

Java has won the TIOBE Index programming Language Award of the year. This is because Java have the largest increase in popularity with one year time (+5.94%). Java leaves runner ups Visual Basic.NET (+1.51%) and Python (+1.24%) far behind. At first sight, it might seem surprising a old language like Java wins this award. Especially if-to-consideration that Java won the same award exactly ago. On second thought, Java was currently number one in the ent

The success of Go language stems mainly from its easy t
As a developer, we really need to learn so many new programming languages. The choices we have now are quite rich, with command languages, functional languages, object-oriented languages, dynamic languages, compiled languages, interpreted languages, and scripting languages, among other things. These programming languages, which are in the forefront of the industry, provide a unique analytical perspective fo

1. Data Types, especially int-related types, have different lengths on the platform of machines with different digits. The c99 standard does not specify the length of a specific data type, but only specifies the level. For comparison:
16-bit Platform
Char, 1 byte, 8 bits
Short 2-byte 16-bit
Int, 2 bytes, 16 bits
Long 4-byte 32-bit
Pointer 2 bytes
32-bit Platform
