Golang program to create a multi-line string using '%Q

In the Go programming language, strings are a built-in data type that represents sequences of characters. They are defined using double quotes (") and can contain any valid Unicode characters. The multi-line will be printed using backticks and the output will be printed on the console using fmt package. Let's see different examples to get a clear understanding of the concept.

The fmt employs the verb %q. To print the string in a format that can be securely included inside double-quoted string literals, use the printf function. This guarantees that any special characters, such as newlines, in the string will be correctly escaped.

Algorithm

• Step 1 ? Create a package main and declare fmt(format package) package in the program where main produces executable Examples and fmt helps in formatting input and output.

• Step 2 ? Create a main function and in that function make a multi_line_string variable and initialize it with a string with many lines.

• Step 3 ? Using the %q verb to format the string such that it may be securely inserted inside double-quoted string literals, output the value of the multi_line_string variable using the fmt.Printf function.

• Step 4 ? A format string and a list of arguments to format according to the format string are passed to the fmt.Printf method. The format string in this instance is "%q," and the parameter is multi_line_string. The string is printed using the %q verb.

• Step 5 ? The print statement is executed using fmt.Println() function where ln means new line.

Example

In the following example we are going to use ?%Q with backticks in main function

package main
import (
   "fmt"
)

func main() {
   multi_line_string := `This is   //create a multiline string a multi-line string given here`
   fmt.Println("The output here is written as:")
   fmt.Printf("%q", multi_line_string) //print the string using %q verb
}

Output

The output here is written as:
"This is   //create a multiline string\na multi-line\nstring given here"

Conclusion

We executed the program of creating a multi-line string using %Q. The verb is used in the example above.
