以下是将给定的代码翻译成C++的结果：

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main() {
    FILE* fp1, * fp2;
    errno_t err1, err2;
    char ch, ch1, ch2;

    if ((err1 = fopen_s(&fp1, "test.txt", "r")) != 0) {
        cout << "Open 1 fail!" << endl;
        exit(0);
    }

    if ((err2 = fopen_s(&fp2, "test2.txt", "w")) != 0) {
        cout << "Open 1 fail!" << endl;
        exit(0);
    }

    while (!feof(fp1)) {
        ch = fgetc(fp1);
        if (ch == '/') {
            if ((ch1 = fgetc(fp1) == '*')) {
                while (fgetc(fp1) != '*' && (ch1 = fgetc(fp1)) != '/');
            }
            else if (ch1 == '/') {
                while ((ch2 = fgetc(fp1)) != '\n');
            }
        }
        else if (ch != EOF) {
            fputc(ch, fp2);
        }
    }

    if (fclose(fp1)) {
        cout << "Close Fail!" << endl;
        exit(0);
    }

    if (fclose(fp2)) {
        cout << "Close Fail!" << endl;
        exit(0);
    }

    return 0;
}

需要注意的是，这个代码使用了 C 语言的库函数和头文件。在 C++ 中，我们通常使用 `<iostream>` 和 `<fstream>` 来进行文件输入输出操作。因此，我们需要对代码做出一些修改。
