{
    int ch = 0;
    char  code1[6]{}, code2[6]{}, n;

这么改，供参考:

void code(account* x, char a[6], char b[6])
{
    int ch = 0;
    char  code1[7]{}, code2[7]{}, n;    // 修改
    cout << "密码：请输入6位数字密码：\n";
    for (n = 0; n < 6;)
    {
        ch = _getch();//输入字符
        if (ch != '\r') {
            code1[n++] = ch;
            printf("*");
        }
    }
    code1[n] = '\0';     // 修改
    cout << "\n确认密码：请再次输入6位数字密码：\n";

    for (n = 0; n < 6;)
    {
        ch = _getch();//输入字符

        if (ch != '\r') {
            code2[n++] = ch;
            printf("*");
        }
        else {
            break;
        }
    }
    code2[n] = '\0';    // 修改

    if (strcmp(code1, code2) == 0)
    {
        cout << "\n确认开户\n";
        x[i].code = atoi(code1);
    }
    else
        cout << "\n两次密码不一致，未成功开户！\n";
}
