  Introduction: Before the possibilities of the new C++ language standard, C++11, the use of templates was quite limited when it came to implementing for instance function objects (functors) & tuple facilities. Implementing these sort of things using…

ES6对字符串新增了一些函数和操作规范.下面我们来看ES6中对字符串新加的特性. 1.模版字符串 (即用反引号定义的字符串) 传统的字符串拼接通过我们使用'+'号与变量连接.例如: let name='HH'; let str='Hello'+name; 在ES6中,引入了 $() 和反引号 ``,新的写法为: let name='HH'; let  age=12; let str=`He is ${name}, he is ${age}.` (注意:这里是反引号) 使用时注意的地方: (1)…

Variadic Templates 1.function template:利用“参数个数逐一递减”的特性,实现递归函数调用 template <typename T, typename... Types> void func(const T& firstArg, const Types&... args) { 处理 firstArg func(args...); } 例一.实现类似 python 3 的 print() void print() { cout <<…

新特性:模板字符串 传统字符串 let name = "Jacky"; let occupation = "doctor"; //传统字符串拼接 let str = "He is "+ name +",he is a "+ occupation; es6简洁的字符串拼接 let name = "Jacky"; let occupation = "doctor"; //模板字符串拼接 le…

模板字符串(Template String)是增强版的字符串,用反引号(`)标识,它可以当作普通字符串使用,也可以用来定义多行字符串,或者在字符串中嵌入变量. 大家可以先看下面一段代码: $("#result").append( "There are <b>" + basket.count + "</b> " + "items in your basket, " + "<em>&q…
