using cplusplus amake a accumulator

Sure, I can help you create an accumulator in C++. Here is an example code:

#include <iostream>

class Accumulator {
  private:
    int count;

  public:
    Accumulator() {
      count = 0;
    }

    void add(int value) {
      count += value;
    }

    int getTotal() {
      return count;
    }
};

int main() {
  Accumulator acc;
  acc.add(5);
  acc.add(10);
  std::cout << "Total count: " << acc.getTotal() << std::endl;
  return 0;
}

In this code, we have defined a class named `Accumulator` which has functions `add` and `getTotal`. The function `add` takes an integer value and adds it to the count, while the function `getTotal` returns the current count of the accumulator.

In the `main` function, we have created an instance of the `Accumulator` class and added the values 5 and 10 to it. Finally, we print the total count using the `getTotal` function.
