键盘输入数字、字符到vector，程序

1.数字

#include<iostream>
#include<vector>
using namespace std;

int main()
{
	vector<int> arr;
	int m=0;
	cout << "输入的元素个数：" << endl;
	cin >> m;
	cout << "m=" << m << endl;
	int tmp=0;
	for (int i = 0; i < m; i++)
	{
		cin >> tmp;
		arr.push_back(tmp);
	}
	for (auto c : arr)
	{
		cout << c << " ";
	}
	return 0;
}

2.字符

#include<iostream>
#include<vector>
using namespace std;

int main()
{
	vector<char> arr;
	char ch;
	cout << "please input test program:" << endl;
	ch = getchar();
	//int i = 0;
	while (ch != '#')
	{
		arr.push_back(ch);
		ch = getchar();
		//i++;
	}
	/*
	for (int j = 0; j < arr.size(); j++)
		cout << arr[j];
		*/
	for (auto ch : arr)
		cout << ch;
	return 0;
}
