How to create a vector of strings in C++? If the list of strings is short, then a very quick way to create the vector is as in the following program: #include <iostream> #include <string> #include <vector> using
//initialization at the time of declaration std::vector<std::string> vec{ "aticleworld", "amlendra","pooja"}; for (std::string x : vec) { std::cout << x << " "; } return 0; } Output: aticleworld amlendra pooja In the above example, I am creating a vector of strings and ...

std map是STL的一个关联容器,它提供一对一(其中第一个可以称为关键字,每个关键字只能在map中出现一次,第二个可能称为该关键字的值)的数据处理能力,由于这个特性,它完成有可能在我们处理一对一数据的时候,在编程上提供快速通道。这里说下std map内部数据的组织,std map内部自建一颗红黑树(一种非严格意义上的平衡...

Not all sequences of bytes are valid Unicode strings. It is unsafe to use Unicode strings in UTF-8 and UTF-16LE without first validating them. Furthermore, we often need to convert strings from one encoding to another, by a process called transcoding. For security purposes, such transcoding...
