看着还是有点复杂,还要用到内存复制,如果用C++11开发,基于C++11强大的STL库支持,使用std::regex_token_iterator和std::vector容器的迭代器参数构造函数vector (InputIterator first, InputIterator last,const allocator_type& alloc = allocator_type())这个split功能可以写得更加简单: 代码语言:javascript 代码运行次数...

Before we wrap up, let’s put your knowledge of JavaScript String to the test! Can you solve the following challenge? Challenge: Write a function to concatenate two strings. Given two input strings (str1 and str2), return the concatenated string. For example, if str1 = "Hello, " and...
正则表达式使用单个字符串来描述、匹配一系列匹配某个语法规则的字符串,被广泛运用于于Scala、PHP、C# 、Java、C++ 、Objective-c、Perl 、Swift、VBScript 、Javascript、Ruby以及Python等等。 目的 给定一个正则表达式(也是字符串)和另一个字符串,我们可以达到如下的目的: ...
JavaScript Code: // Define a function named 'test' with a single parameter 'text'consttest=(text)=>{// Check if the input string is emptyif(text.length===0){// Return a message if the input string is emptyreturn'String should not be empty!'}// Check if the input parameter 'text...
