Is there a library or something for c++?

I have learned vb php js before, now I want to learn c++ and make a *.dll file for other software to use.

When I was learning, I found that processing a string is also very troublesome. For example, to split a string into an array, you need to write a function yourself. I can write it, but it is too inefficient to write everything myself.

I looked at the manual and found that there are not many functions in C++, such as those for processing arrays and strings. I couldn’t find them. My level is limited and I can’t understand English web pages..

Do you have a library?

Achieve effects of types in other languages, such as PHP’s explode, implode, str_replace, strstr?

If yes, how to import it?

There are many libraries. C++ has its own standard library std, quasi-standard library boost, Qt, etc. There are a lot of [C++ open source libraries] searched.
Separate strings into arrays. This does not require writing a function. std::string is the string class of the standard library and can be accessed using subscripts:

<code>#include <iostream>
#include <string>

int main()
{
    std::string str = "HelloWorld";
    std::cout << str[5];
    return 0;
}
输出:W</code>

explode, implode, str_replace, strstr are all implemented in C++.
In fact, unless it is a very emerging demand, the functions required for programming can basically be found. Various wheels have been re-created countless times. Make good use of search technology, Baidu, Google, github, SourceForge Wait, you can find it in search engines and various open source code hosting websites.
