C Remove punctuation from string

#include 

int main() {

string text = "this. is my string. it's here."

if (ispunct(text))
text.erase();

return 0;
} 

string text,result;
std::remove_copy_if(text.begin(), text.end(), 
 std::back_inserter(result), //Store output < br /> std::ptr_fun(&std::ispunct) 
 );

I have a string and I want to delete it All punctuation. How do I do it? I did some research and found that people use the ispunct() function (I tried), but I can't seem to get it to work in my code. Does anyone have any ideas?

#include 

int main() {

string text = "this. is my string. it's here."

if (ispunct(text))
text.erase();

return 0;
}
Use algorithm remove_copy_if: – 
 
 
string text,result; 
std::remove_copy_if(text.begin(), text.end(), 
 std::back_inserter(result), //Store output 
 std::ptr_fun (&std::ispunct) 
 );
