C++ Remove punctuation from String

C++ Remove punctuation from String

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 cant seem to get it to work in my code.
Anyone got any ideas?
#include <string>
int main() {
string text = "this. is my string. it's here."
if (ispunct(text))
text.erase();
return 0;
}
