Usage of Turbo C 2.0 and Its configuration in editplus

Before reading this article, I will first describe how to install and use C language:
After downloading Turbo C 2.0 and Turbo C ++ 3.0, many netizens asked me most about the following problems during use:
1) The include files such as stdio. h conio. h cannot be found;
2) Cos. OBJ cannot be connected.
These problems are caused by the absence of a set path. Currently, the downloaded TC2 and TC3 are classified into two versions by installation: first, install the TC2 and TC3, which should have already been configured with the path; second, directly decompress the package and establish TC. EXE shortcut, double-click in Windows to run (DOS directly run TC. EXE). Currently, most of them are in China. (because I recommended the English version of TC2 that I uploaded to my 269 network home to more than 10 software sites in the previous section), please pay attention to the path settings before downloading and using it:
Set to: Option-> directories:
Include: [TC2/3 Directory]/include
Lib: [TC2/3 Directory]/lib
Set a working directory for the output directory to avoid mixing.
Note that the change Dir (Change current directory) in files should be set to the directory where the current program is located.
I. Origins of C Language

C language was designed and invented by Dennis Ritchie of the United States in 1972.
Is used on the DEC PDP-11 computer. It consists of the early programming language BCPL (Basic Combind
Programming Language) has evolved. In March 1970, Ken of the at&t Bell lab
Thompson designed a more advanced language named B Based on BCPL, and finally introduced the advent of C language.
With the increasing popularity of micro-computers, many c-language versions have emerged. Because there is no unified standard,
This makes some inconsistencies between these C languages. To change this situation, American National Standards
The Institute (ANSI) has developed an ANSI standard for the C language and has become the current C language standard.
Ii. Features of C Language
C language has developed so rapidly and has become one of the most popular languages, mainly because it has powerful
Function. Many well-known system software, such as DBASE ⅲ plus and dbase iv, are written in C language.
Using C language with some assembly language subroutines can better display the advantages of C language, such as PC-dos,
WordStar is written in this way. C language has the following features:
1. c is an intermediate language
It combines the basic structure and statements of advanced languages with the practicability of low-level languages. C language can be like
The assembly language performs operations on the same position, byte, and address, and these three are the most basic work units of the computer.
2. C is a structured language
The distinctive feature of structured language is the separation of code and data, that is, each part of the program is not only necessary
Information exchange is independent of each other. This structured method makes the program layers clear, easy to use, maintain, and adjust
Try. The C language is provided to users in the form of functions. These functions can be conveniently called and have a variety
Loop and conditional statements control program flow direction, so that the program is fully structured.
3. Complete C language functions
C language has a variety of data types, and introduces the pointer concept, can make the program more efficient. Another
The external C language also has powerful graphics Functions and supports multiple monitors and drives. And computing functions and logic
The judgment function is also powerful and can be used for decision-making purposes.
4. Wide application of C Language
C language also has a prominent advantage: it is suitable for a variety of operating systems, such as DOS, UNIX, and also suitable
Multiple models.
Iii. Turbo C Overview
1 generation and development of Turbo C
Turbo C is a product of Borland Corporation in the United States. Borland Corporation is specialized in software development,
Developed by a large company. The company has successively released a set of Turbo software, such as Turbo BASIC and Turbo
Pascal and Turbo Prolog are very popular among users. The company launched turbo for the first time in 1987
The C 1.0 product uses a completely new integrated development environment, that is, a series of drop-down menus,
The integration of text editing, program compilation, connection, and program running greatly facilitates program development. 1988
Borland also launched the turbo c1.5 version, adding graphics libraries and text window function libraries.
Turbo C 2.0 was published by the company in 1989. Based on the original integrated development environment, Turbo c2.0
The error checking function is added and can be directly generated in tiny mode. com (data, code, and stack are in the same
64 K memory) file. It can also simulate a mathematical co-processor (8087/80287/80387 supported.
Borland later launched the object-oriented program package Turbo C ++, which inherits the development
The integrated development environment of Turbo C 2.0 contains basic object-oriented ideas and design methods.
In 3.0, Borland added the Turbo
C ++ has been updated, that is, Borlandc C ++, a new generation of Turbo C, has also been released.
2 Basic Configuration Requirements for Turbo C 2.0
The Turbo C 2.0 can run on IBM-PC series microcomputer, including XT, at and IBM compatible machines. In this case
Supported by DOS 2.0 or later, and requires at least k ram, which can be on any color, monochrome 80-column Monitor
Run. Supports the mathematical coprocessor chip or floating point simulation, which will speed up program execution.
