各位网友们，
                 我有个问题关于C++ Programming下请教一下，问题如下；
                 Assume that array X contains 10 integers.
                 (i) Write the function definition for doubleValue, that receives the array X as input parameter, multiplies the value of each array element by 2 and displays the new contents of array X.

如果会的，请回复我，小弟感激不尽！！

Is my answer correct?

void double(int * x){
          y = x * 2;
}

printf("%d", &y);


Please provide me your comment if you found any wrong/mistake, thanks alot!! ^^

void doubleValue(int input[]){
    for(int i=0; i<10; i++){
        input[i] *= 2;
        printf("input[%d] = %d", i, input[i]);
    }
}

很久没碰C++了，加上没有visual C++来run。所以有问题就自行debug吧。

哦，好的，谢谢！！可是在program里面没看见有什么output喔！！

and this is the 2nd question,
write a function definition for getData to prompt and read the customer's current balance (currentBal) in RM and the total minutes (totalMin) of phone calls from the user. The function will return the customer's current balance and output the total minutes via a reference parameter.

请问有哪位C++ Programming 会做这题？可以帮小弟回答一下？多谢！！！

modern c++ 用vector不用array.

and this is the 2nd question,

int getData( int currentBal, int *totalMin ){
cout << "Please insert customer's current balance and total minutes of phone call" << endl;
cin >> currentBal >> *totalMin;
return currentBal;
};


不要嫌弃，我也不是pro，还在college学习罢了。
btw，我相信楼主已经解决问题了，只是路过看到想要试试看这个题目罢了，不懂对不对？
