When we encounter multiple statement branches, do we first think of switc case and if else if... These two methods are simple in coding, but when the number of branches reaches a certain level, especially when the branches have nested large

C, The int and long ranges are the same and can only be expressed (-2 ^ 31 ~ 2 ^ 31) INTEGER (-2 billion ~ 2 billion) The range of unsigned int and unsigned long is (0 ~ 2 ^ 32), 4 billion more. If you want to represent larger integers, these

I. Overview First-in-first-out data structure, adding elements at the bottom, and removing elements at the top. Similar to the stack, no traversal behavior and no iterator are allowed. The container is also classified as the container adapter at

1. Message Overview In Windows, the execution of applications is message-driven. Message is the working engine of the entire application. We need to understand how the programming language we use encapsulates messages. 1. What is a message) Messages

We know that a language can be divided into two categories: Strong-type languages, such as C #, Java, C, and weak-type languages, such as JavaScript. Each variable in a strong-type language must have a specific type, such as int and double, but a

In the C ++ programming language, many functions are connected with the C language, such as pointer applications. Here we will introduce a C ++ function object similar to a function pointer. The C ++ function object is not a function pointer.

Difference between malloc/free and new/deleteMalloc/free is a standard library function in C language, and new/delete is a C ++ operator.Because malloc/free is a library function rather than an operator, it is not controlled by the compiler.For
