Each statement does not need to be semicolon-like other languages in the C family; End, because all of this work will be done automatically by the Go compiler.If you intend to write multiple statements on the same line, they must be used; , but we do not encourage this practice in practical development.Lesson three basic grammar of

Self is used in the method to represent the method caller, who calls this method and self represents who. You can use self to invoke other class methods or object methods. If you call other methods of the object in the object method, you can use self to invoke: -(void) bark{N

This is a creation in Article, where the information may have evolved or changed. # # Pre-order (Prelude) This series contains a total of four articles that help you understand some of the grammatical structures in the Go language and the design principles behind them, including pointers, stacks, heaps, escape analysis, and values or pointer passing. This is the last article that focuses on the design philosophy of using values and pointers for data

statement understanding, you do not have to learn what "priority" rules, and do not have to ignore what "right-left" rules, you just press left-to-right in order to read the code, Complex variable declarations can also be easily understood. Why does the go language use this kind of reverse grammar? Go's designer Rob Pike, an article on Go Declaration syntax, gives an answer to the design considerations for

it completely. in C, spaces are used to describe whitespace characters, tab characters, line breaks, and comments. Spaces separate the parts of the statement so that the compiler can recognize where an element in the statement (such as int) ends and where the next element begins. Therefore, in the following statement: Keywords in 7,cStart by year: Auto break case Char ; const Continue default do Double else enum extern Flo At for Go

a statement or statement group when the given condition is true. It tests the condition before executing the loop body. For loop Executes a sequence of statements multiple times, simplifying the code for managing loop variables. Do...while Cycle The other is similar to the while statement except that it is a test condition at the end of the loop body. Nested loops You can be in while, for, or do: Use one or more loops within a while lo
