Help with String functions

I am having trouble with finding and erasing part of a string. For example, the string "pork and beans". We had to find the first occurrence of "and" and place "not" after the "and" to make it "pork and not beans"

Then we are supposed to erase the "not".


all remove() to remove " not" from the string str. The function remove() will receive str as a reference parameter. After changing str, remove() will print the changed string.

So far I've come up with this:

Code:

---

void remove (string &str)
{
    string::size_type pos;
   
    pos = str.find ("not", 0);
    str.erase (pos, str.length());
   
    cout << str << endl << endl;
 }

---

The second parameter in the erase function is way off, I know. I was just trying anything. I'd appreciate anyones helpn

The second parameter to erase should be the number of characters to erase, right?

This is a little hacky, but you get the idea...

Code:

---

#include <iostream>
#include <string>

using namespace std;

int main()
{
        string::size_type pos;
        string str("pork and beans");
        string str_to_find("and");
        pos = str.find (str_to_find, 0);
        str.insert (pos + str_to_find.size(), " not");
        cout <<str <<endl;
}
