Analysis of Process-Oriented Thought in C Language

In computer science, a programming language is the bridge between programmers and computers. As a very important programming language, C language has a profound influence on modern programming languages due to its process-oriented thinking. This article will discuss the process-oriented thinking of C language, and analyze its advantages and disadvantages.

What is process-oriented thinking

Process-oriented programming is a process-centric programming paradigm. In process-oriented programming, a program is broken down into individual steps (ie, procedures), each of which accomplishes a specific task. These processes are executed in sequence, and the functions of the program are realized by passing data. Process-oriented thinking pays attention to the flow control of the program, emphasizing the steps and methods to solve the problem.

Process-Oriented Thought of C Language

The C language is widely regarded as a typical procedural programming language. It was originally designed for developing operating systems, so it focuses on efficiency and flexibility. The following are several procedural-oriented features of the C language:

1. Concise and clear syntax

The syntax of C language is simple and clear, easy to understand and learn. It provides a basic set of control structures, such as sequential execution, conditional statements, and loop statements, that enable programmers to express the steps to solve a problem in an orderly manner.

2. Powerful and flexible pointer operation

Pointers in C are a powerful tool that allow programmers to directly access data in memory. This ability to directly access memory allows C to efficiently handle low-level details such as arrays and strings.

3. Free memory management

In the C language, programmers are very free to manage memory. Memory can be allocated and freed manually, which means that programmers can dynamically manage memory resources based on demand. While this brings more responsibility and risk, it also gives programmers more flexibility

explanation in life

When we relate procedure-oriented programming of C language to our daily life, we can use a simple example to explain it. Suppose we want to make a cup of coffee.

In process-oriented thinking, we break down a task into a series of steps, and each step is performed in a sequential manner.

First of all, we need to prepare materials and tools: coffee beans, grinder, filter paper, filter cup, kettle and cups. This is equivalent to defining and declaring variables or data types in programming.
Next, we put the coffee beans in the grinder and press the button to grind them. This is similar to performing a specific operation or function in a program.
Then, we'll take a piece of filter paper and put it in the filter cup. This is providing the appropriate input or parameters to the program.
Pour the ground coffee beans into the filter cup, and turn on the switch in the kettle to inject hot water. It's like calling a function in a program and passing parameters.
As the hot water drips into the filter cup, the coffee seeps through the filter paper and into the cup. This is similar to the output produced during program execution.
Finally, we pour the coffee into the cup and finish the process of making the coffee. It's like the program finishes executing and returns the result.

Through this example, we can see that the way of thinking about process-oriented programming is similar to the way of solving problems step by step in life. In procedural programming in C, we decompose a task into a series of steps and execute these steps in a specific order to achieve the final goal. Just like making coffee, each step has its specific function and operation, and the order in which each step is performed is critical to the final result.

Disadvantages of process-oriented:
When developing large-scale projects, it will become more and more difficult to control. There are too many details to consider, and it is easy to ignore or even lose control
. Moreover, the maintenance and update costs in the later period are very high.
