Question

（C ++）我的程序应该让用户输入数字，这些数字将决定数组的大小以及它的元素。然后我需要按升序排列元素。我的问题是每当我运行我的程序并显示已排序的数字;相反，它显示地址（如果我是正确的。）

    #include <iostream>
    using namespace std;


int main()
{

   int size;
   int i,x,tempVar;
   cout << "Enter how many students took the test: ";
   cin >> size;
   int *myArray = new int [size];

for  ( i = 0; i < size; i++)
{
    cout << "Enter a score:  ";
    cin >> myArray[size];
}

for ( i = 0; i < size; i++)
{
    for ( x = 0; x < size; x++)
    {
        if (myArray[i] < myArray[x])
        {
            tempVar = myArray[i];
            myArray[i] = myArray[x];
            myArray[x] = tempVar;
        }
    }
}

cout << "The scores have been sorted out in an ascending order\n";
for (i = 0; i < size; i++)
{
    cout << *(myArray + i) << endl;
}

delete [] myArray;
}

Answer 1

它没有显示地址;它可能显示垃圾值，因为你有：

cin >> myArray[size];

而不是

cin >> myArray[i];

指针表示法和数组
