Regardless of the programming language, the processing of words is important. After all, in a computer system, many settings are operated directly through text.

Therefore, the note in this section mainly record how to input and output text, as well as record read and write file at the same time.

Use Symbolic Constants is a way to improve the "source code readability". Just like the classic conversion between Celsius and Fahrenheit, the lower, upper, and step of the boundary value and the updated value are actually meaningful numbers, especially the temperature boundary value.

In the previous note, I recorded how to program conversion between Celsius and Fahrenheit ([C] Variables and Arithmetic Expressions). In the process, we continuously increase the Fahrenheit temperature through the while loop, and view the converted Celsius temperature result.

If you want the program to execute the same command over and over again, you can also use a for loop to do this.

The most important function of computer invented is to assist humans in computing. So, in this section, we use the conversion between Celsius (°C) and Fahrenheit (°F) to explain which is variable and which is an arithmetic expression.

C Programming Language is one of the most common programming languages, and it can be seen in many Unix systems. Many systems and programs are also developed using C.

Therefore, the C language can be said to be a programming language with absolutely no harm when it is familiar to programmers.
