Computer languages include machine language, assembly language, and high-level language. Machine language is a collection of machine instructions expressed in binary code that a computer can directly recognize and execute. It is the designer of the computer through the computer’s hardware structure to give the computer operation function, such as assembly language (assemblylanguage). Machine language is characterized by flexibility, direct execution and speed. High-level languages are easier to recognize and understand, like CB language.
The four steps of C program development are, in order?
Importing and editing the source program – Compiling the source program – Linking with library functions – Running the executable target program.
What are the four steps involved in developing a C program
Provide the answer (fill in the blanks) to Computer Exam Question Bank:
There are four basic processes involved in developing – a C program: ______, ______, ______, and ______.
Answer: editing compiling linking running
Expanded Explanation:
1. Editing: writing the source program code (.c, .h files)
2. Compiling: compiling the source code into an object file (.OBJ file)
3. Linking: generating the object file into an executable file (. EXE file)
4. Run: Execute the .
1.Write C program four steps are:———,——–,——–,——–.?
Four steps? The first time I heard someone say this, if you write a very large amount of code program, it can be hundreds or even thousands of lines of code, there is no specific step ah! If the framework, it is generally
#include<stdio.h><> brackets are you need to include header files, is the specific case.
voidmain() the main function to start, which is all there is, but also int-type.
{
}
I don’t know if my answer can help you!
History of C program development
The prototype of C, ALGOL60 language. (also known as Language A) In 1963, the University of Cambridge developed the ALGOL60 language into the CPL (CombinedProgrammingLanguage) language.In 1967, Matin Richards of the University of Cambridge simplified the CPL language, thus giving rise to the BCPL language.In 1970, Bell Labs’ In 1970, Ken Thompson of Bell Labs modified BCPL and gave it an interesting name “B language”. It means to boil the CPL language dry and extract its essence. He wrote the first UNIX operating system in B language. In 1973, the B language was also “boiled”, and D.M. RITCHIE of Bell Labs finally designed a new language based on the B language, and he took the second letter of BCPL as the name of the language, which is the C language. In order to make the UNIX operating system popularized, in 1977 DennisM.Ritchie published the C language compilation text which does not depend on the specific machine system, “Portable C Compilation Program”. In 1978, Brian W. Kernighian and Dennis M. Ritchie published the famous book “C language program” (TheCProgrammingLanguage), thus making the C language became the world’s most popular and widely used high-level programming language. 1988, with the growing popularity of the microcomputer, the C language appeared. In 1988, with the increasing popularity of microcomputers, many versions of the C language appeared. Due to the lack of a unified standard, there were some inconsistencies between these C languages. In order to change this situation, the American National Standards Institute (ANSI) developed a set of ANSI standards for the C language, which became the current C language standard.3. The main features of the C language. C language has developed rapidly and become one of the most popular languages, mainly because of its powerful functions. Many famous system software, such as DBASE Ⅲ PLUS, DBASE Ⅳ are written by the C language. C language with some assembly language subroutines, it is more able to show the advantages of the C language, such as PC-DOS, WORDSTAR and so on is written in this way.
Shortly describe what are the steps in developing a C program?
1 Write the code. This is the most basic step, i.e., implementation of C language source files (.c, required), and possibly header files (.h, non-required).
2 Compilation. The written code is converted into a target file by a compilation tool. In this step, the file’s internal and included header files are analyzed and checked for syntax semantics. If an error occurs, the code must be returned to a step to make changes until there are no errors.
3 Linking. Links the target file into an executable. This step will check the direct linking of the file. If there is an error you need to return to 1 to modify the code. Until there are no errors.
4Run. This is the final step and the ultimate goal of C.
5 In case the result of running is not as expected, you need to check the reason, modify the code and re-execute one, two, three until the program is fine.
(1) The language is simple, compact and flexible. Twenty-eight keywords, nine kinds of control statements, program form free, rich operators. Thirty-four kinds of operators.
(2) Rich data types, with a variety of data structures of modern languages.
(3)The main structure of C program is function, it is completely modular and structured language.
(4) It allows direct access to physical addresses, can perform bit manipulation, can realize most of the functions of assembly language, and can operate directly on hardware. It has the characteristics of both high-level and low-level languages.
(5) Program portability is good (compared with assembly language). It can be used in various types of computers and various operating systems basically without modification.
(6) High quality of object code and high efficiency of program execution. Only 10-20% less efficient than the assembly program generated by the target code.
(7) less strict syntax restrictions, program design freedom.
What are the steps to make a c program using CB development platform?
Install CB platform
1, add a button control on the interface
2, double-click the button, write code at the cursor blinking, you can write C code.

1. In the source program, many of the symbols are paired. appear, in order to avoid missing symbols that must be used in pairs.
2, the part enclosed in curly brackets, but from the point of view of the program structure is clear, easy to read, understand, maintain, it is recommended to write the program should follow the following rules in order to develop good programming habits.
3, a description or a statement occupies a line, aligned with the left curly bracket at the beginning of the structure.
