Edit a character string with an assigned variable

Hi I am a little new to programming and am a little frustrated. I am trying to figure out how to edit a character string that has been assigned a variable name. For example:

line = Sam, I am.

I think I have to use something like the code below, but I want to use the variable line or find a way to get the string into the function with quotes.

string str("Sam, I am.");
cout << str << endl;
str.erase(remove_if(str.begin(),str.end(),ispunct) ,str.end());
cout << str << endl;
return 0;

Is there a way to pass the string this way?

I don't completely understand your problem. Do you mean something like this?

Code:

---

#include<string>
#include<iostream>

int main()
{

    char line&#091;&#093;="Sam, I am.";
    std::string str(line);
    std::cout << str << std::endl;
    str.erase(remove_if(str.begin(),str.end(),ispunct) ,str.end());
    std::cout << str << std::endl;
   
    std::cin.get();
    return 0;
}

If you want to include quotes in a literal string you have to escape them.

Code:

---

std::string s = "\"Sam, I am.\"";
std::cout << s << std::endl;

---

this outputs "Sam, I am." with the quotes and everything. I am afraid I don't really understand the question.
