Try to do the character delete for an array

Question

My question is that if I want to run a C++ program, which needs to input two things:

string A,
string B,

the Program's purpose is to remove all occurrences of B from A.

Ex: A = adferttyu, B = adf

Output: erttyu.

What is your question ? What you give us is question that someone asked _you_. So what have you already tried to answer it? — Garf365, Oct 05 '16 at 12:41

I think you don't want to run a C++ program (If I got your question correctly). — Ped7g, Oct 05 '16 at 13:37
Please [edit] your question to show [what you have tried so far](http://whathaveyoutried.com). You should include a [mcve] of the code that you are having problems with, then we can try to help with the specific problem. You should also read [ask]. — Toby Speight, Oct 05 '16 at 16:45
Perhaps there's an implementation of sed in C++. That would certainly achieve your aims if it exists. — Toby Speight, Oct 05 '16 at 16:46

This removes all substrings from a string

#include <string>
#include <iostream>

using namespace std;

void removeSubstrs(string& s, string& p) { 
  string::size_type n = p.length();
  for (string::size_type i = s.find(p);
      i != string::npos;
      i = s.find(p))
      s.erase(i, n);
}

int main() {

  string A = "adferttyu";
  string B = "adf";

  removeSubstrs(A, B);
  cout << A << endl;
}

Output: erttyu
