HomeBackend DevelopmentGolanggolang printf escape

当我们在使用Golang中的printf函数时,有时我们需要在输出字符串中使用一些特殊字符,如引号、反斜杠、制表符等。在这种情况下,我们可能需要使用转义字符来表示这些特殊字符,以确保它们被正确地显示在输出字符串中。

在Golang中,printf函数中的转义字符以“\”开头,它们用来表示一些预定义的特殊字符或者是一些特殊的二进制值,如下表所示:

转义字符 描述
\a 响铃声(ASCII码值07)
\b 退格符(ASCII码值08),将当前位置移到前一列
\f 换页符(ASCII码值12),将当前位置移到下一页开头
\n 换行符(ASCII码值10),将当前位置移到下一行开头
\r 回车符(ASCII码值13),将当前位置移到本行开头
\t 水平制表符(ASCII码值09),将当前位置移到下一个水平制表符位置上,如果没有则移动到下一行
\v 垂直制表符(ASCII码值11),将当前位置移到下一个垂直制表符位置上,如果没有则换到下一行
\ 反斜杠
\' 单引号
\" 双引号
\xhh 以十六进制值hh表示的一个字符
\ooo 以八进制值ooo表示的一个字符
\uhhhh 以十六进制值hhhh表示的Unicode字符
\Uhhhhhh 以十六进制值hhhhhh表示的Unicode字符

在使用转义字符时,我们只需要在需要转义的字符前加上“\”即可。例如,如果我们需要在输出字符串中显示一个双引号,我们可以使用“\"”来代替转义后的双引号,如下所示:

fmt.Printf("Hello, \"Golang\"!") // 输出结果:Hello, "Golang"!

如果我们需要在输出字符串中显示一个反斜杠,我们可以使用“\”来代替转义后的反斜杠,如下所示:

fmt.Printf("C:\\Windows\\System32\\") // 输出结果:C:\Windows\System32\

当我们需要在输出字符串中显示一些特殊字符时,我们应该注意使用转义字符来表示这些特殊字符。这样可以确保我们的输出结果是正确的,并且可以避免一些潜在的错误。

Golang and Python: Understanding the DifferencesGolang and Python: Understanding the DifferencesApr 18, 2025 am 12:21 AM

The main differences between Golang and Python are concurrency models, type systems, performance and execution speed. 1. Golang uses the CSP model, which is suitable for high concurrent tasks; Python relies on multi-threading and GIL, which is suitable for I/O-intensive tasks. 2. Golang is a static type, and Python is a dynamic type. 3. Golang compiled language execution speed is fast, and Python interpreted language development is fast.

Golang vs. C  : Assessing the Speed DifferenceGolang vs. C : Assessing the Speed DifferenceApr 18, 2025 am 12:20 AM

Golang is usually slower than C, but Golang has more advantages in concurrent programming and development efficiency: 1) Golang's garbage collection and concurrency model makes it perform well in high concurrency scenarios; 2) C obtains higher performance through manual memory management and hardware optimization, but has higher development complexity.

Golang and C each have their own advantages in performance efficiency. 1) Golang improves efficiency through goroutine and garbage collection, but may introduce pause time. 2) C realizes high performance through manual memory management and optimization, but developers need to deal with memory leaks and other issues. When choosing, you need to consider project requirements and team technology stack.

Golang is more suitable for high concurrency tasks, while Python has more advantages in flexibility. 1.Golang efficiently handles concurrency through goroutine and channel. 2. Python relies on threading and asyncio, which is affected by GIL, but provides multiple concurrency methods. The choice should be based on specific needs.

Golang and C  : The Trade-offs in PerformanceGolang and C : The Trade-offs in PerformanceApr 17, 2025 am 12:18 AM

The performance differences between Golang and C are mainly reflected in memory management, compilation optimization and runtime efficiency. 1) Golang's garbage collection mechanism is convenient but may affect performance, 2) C's manual memory management and compiler optimization are more efficient in recursive computing.
