vector创建二维数组

int main() {
		vector<vector<int> > array(4);
		for (int i = 0; i<4; i++) {
			array[i].resize(5);
		}
		//输出二维数组的行和列 
		cout << "Row:" << array.size() << " Column:" << array[0].size() << endl;
		//输出二维数组 
		cout << "[" << endl;
		for (int j = 0; j<array.size(); j++) {
			cout << "[" << " ";
			for (int k = 0; k<array[0].size(); k++) {
				cout << array[j][k] << " ";
			}
			cout << "]" << endl;
		}
		cout << "]" << endl;
		return system("pause");
