If you want to print a string data type variable in C programming language, you can use the following code:

A structure is a type that stores multiple related variables (variables that may contain multiple different data types) under one-name for easy control.
In C programming language, we can declare a structure by keyword struct:
A pointer is a variable that contains the address of a variable. Generally speaking, when we declare and assign a variable to the system today, the program will apply for space in the memory to store :

Generally, function is a bit like formula: we input something, and the executed result will be generated.

In C programming language, we can declare a variable to represents the entire array. For example, the format x[10] means that there are 10 records stored in the x array, and the index are from 0 to 9.
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.

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.
Read More »[C] Introduction of Symbolic Constants 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.

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