Question

Can someone help me . This program needs to run in visual studio and written in c++. I want to call to the function string eraseChar in the main function to use the variables str and ch. I cannot use global variables.

#include<iostream>
#include <string>

using namespace std;
string eraseChar(char ch = 'e', string str = "the bike fell in the water");
  

int main()
{
   int pos;
   pos = str.find(ch);
   while (pos != string::npos)
   {

       str.erase(pos, 1);
       pos = str.find(ch);
   }
   cout << str << endl;
   system("pause");
   return 0;

}
