C++ Remove punctuation from String

Question

I got a string and I want to remove all the punctuations from it. How do I do that? I did some research and found that people use the ispunct() function (I tried that), but

I tried to apply @Steve314's answer but couldn't get it to work until I came across this note here on cppreference.com:

Notes

Like all other functions from , the behavior of std::ispunct is undefined if the argument's value is neither representable as unsigned char nor equal to EOF. To use these functions safely with plain chars (or signed chars), the argument should first be converted to unsigned char.

By studying the example it provides, I am able to make it work like this:

#include 
#include 
#include 
#include 

int main()
{
    std::string text = "this. is my string. it's here.";
    std::string result;
    text.erase(std::remove_if(text.begin(),
                              text.end(),
                              [](unsigned char c) { return std::ispunct(c); }),
               text.end());
    std::cout << text << std::endl;
}
