What are the golang flow control statements?

Common flow control statements include if statements, for loops, switch statements, select statements, break and continue statements, and goto statements. Detailed introduction: 1. if statement: used to conditionally execute a block of code; 2. for loop: used to repeatedly execute a block of code; 3. switch statement: used to select and execute different blocks of code based on the value of an expression; 4. Select statement: used to process channel operations; 5. break and continue statements, etc.

Go language (Golang) provides common flow control statements, including:

1. if statement: used for conditional execution A block of code.

if condition {
    // code to be executed if the condition is true
} else {
    // code to be executed if the condition is false
}

2. for loop: used to repeatedly execute a block of code.

for i := 0; i < 10; i++ {
    // code to be executed in each iteration
}

There are other forms of for loops, such as for range for traversing arrays, slices, strings, etc.

3. Switch statement: Used to select and execute different code blocks based on the value of an expression.

switch variable {
case value1:
    // code to be executed if variable == value1
case value2:
    // code to be executed if variable == value2
default:
    // code to be executed if variable doesn't match any case
}

4. Select statement: Used to process channel operations.

select {
case <-channel1:
    // code to be executed if channel1 can be read
case channel2 <- value:
    // code to be executed if value can be written to channel2
default:
    // code to be executed if no channel operation can proceed
}

5. Break and continue statements: Used to control the flow in a loop, break is used to jump out of the loop, and continue is used to skip the remaining code of the current loop and enter the next iteration.

6. Goto statement: Allows unconditional transfer to another part of the code. Misuse of goto is not recommended as it can make the code difficult to understand and maintain.

These are commonly used flow control statements in Go language. Please note that the Go language is more concise than other languages ​​and does not support the traditional while loop. Instead, it uses a variant of the for loop to achieve the same effect.
