There is a personal computer for each seat, and you can write and execute your preferred language. Of course coffee uses Java beans. Menu prices are in hexadecimal.
When the weather is good, seats may be set outdoors and it is called "dynamic memory allocation" among regular customers.
C's pointer to function
2020/11/14
If you want to pass a function as an argument in C language, pass it as a pointer to the function. The first time I touched this was the Windows callback function. I set a function in the WNDCLASS structure and passed it.
Java's lambda expression

A lambda expression that can write function literals was introduced from Java8. The reality is an interface with one method. It is convenient to write by simply connecting the argument list and method body with "->".
Java's diamond operator
2016/07/24
Java has a function called generics. For example, it determines the type of elements such as lists. If it is ArrayList <String>, it becomes ArrayList that stores String. ArrayList <> and types can be omitted when creating with the new operator. I see, “<>” looks like a diamond.
C's pointer

The C language has a function called a pointer. This is a record of the address, but if you understand this, you can see the meaning of other language reference types. Some pointers, such as pointers, take time to understand depending on the combination.
C's main function return value

When I learned in class, I wrote "void main ()", but the main function seems to return int. There are many sample programs that return 0 upon successful completion.
C language's Omajinai

C sample programs often start with "#include <stdio.h>". When this meaning is understood, it becomes fun. You are serious, not serious (laughs).
