algorithm标准库中,有针对 vector类型的泛型算法,比如 find(), sort(), stable_sort() 等等函数,其基于迭代器。 但string 类型的迭代器不常用,当用到算法的时候,string类型有其自己的一套“私人武器“。 比如str.find(),应用如下所示: std::string myString ="Hello, world!";size_tfound = myString.find...
深入探讨 C++ 标准库 <string> 在C++ 的标准库中,<string>是一个基础而又功能强大的组件,广泛应用于各类程序开发中。它提供了对字符序列的高级抽象,能够高效处理动态字符串操作。std::string是基于动态内存管理的类,克服了 C 风格字符串(char数组)在长度和安全性上的局限性。无论是小型实用工具,还是企业级应用开...

C++中的string.substr()函数是用于从一个字符串中提取子字符串的函数。它的编译方式在不同的编译器中可能会有所不同。 在C++标准中,并没有明确规定string.substr()函数的具体实现方式,因此不同的编译器可能会采用不同的实现方式。一般来说,string.substr()函数的实现方式可以分为以下两种: 拷贝方式:某些编译器会...
