如何在字符串中加上单引号? [英] How can I put single quotes in a string?

问题描述

我在MATLAB中遇到字符串问题，默认字符串为C:\Users\Root\Downloads\Path.我想像这样的'C:\Users\Root\Downloads\Path\'那样用单引号使它成为字符串.与其他编程语言一样，我多次尝试使用反斜杠对字符串进行转义，但MATLAB却没有这样做，我不知道如何解决此问题.

I'm facing a problem with string in MATLAB the default string is C:\Users\Root\Downloads\Path. I want to make this string with single quotes inside it like this 'C:\Users\Root\Downloads\Path\'. I try many times to escape the string with backslash like other programming languages but MATLAB didn't doing this i don't know how to fix this problem.

代码:

clear all
clc
s='C:\Users\Root\Downloads\Path';
str=fprintf('%s',s);

推荐答案

技巧是使用两个引号而不是一个引号:

The trick is to use two quotes instead of one:

s='''C:\Users\Root\Downloads\Path''';    
str=fprintf('%s',s)
'C:\Users\Root\Downloads\Path'
str =    
    30

请注意，str将是数字30，因为fprintf返回其打印的字符数，而不是字符串本身！如果只需要字符串，那么第一行就足够了.

Note that str will be the number 30, since fprintf returns the number of characters it prints, not the string itself! If you just want the string, then the first line is enough.

disp(s)
'C:\Users\Root\Downloads\Path'

请注意，MATLAB中没有数据类型"String".您有一个字符数组.

Note that there is no data type "String" in MATLAB. You have an array of characters.
