1. How to use C++ input and output

1. Input

The code is as follows (example):

#include <iostream>
using namespace std;
int main()
{
	int x = 10;
	double y = 11.11;
	char z[20] = "hello world";

	cin >> x >> y >> z;
	cout << x << endl;
	cout << y << endl;
	cout << z << endl;
	return 0;
}

 The result is as follows: 

analyze:

cin (for input)

>> (extract for stream)

cin>>any;

2. Output 

The code is as follows (example):

#include <iostream>
using namespace std;
int main()
{
	int x = 10;
	double y = 11.11;
	char z[] = "hello world";
	cout << "你好" << endl;
	cout << x << endl;
	cout << y << endl;
	cout << z << endl;


	return 0;
}

The result is as follows: 

​ 

analyze:

cout (for output)

<< (for stream)

endl (line feed)

cout<< can be any <<endl;
