C++笔记：习题4.28
Exercise 4.28: Write a program to read the standard input and build a vector of ints from values that are read. Allocate an array of the same size as the vector and copy the elements from the vector into the array.
#include <iostream>
#include <vector>
using namespace std;
typedef vector<int> arr_int;
int main()
{
int value;
arr_int a = arr_int();
// 输入元素数据。
while (cin >> value)
{
a.push_back (value);
}
int * sz = new int [a.size()];
arr_int::iterator iter = a.begin ();
while (iter != a.end ())
{
*sz = *(iter++);
cout << *sz << endl;
}
return 0;
}
