Input and Output

➤ C++ Basic Input/Output

 

In this tutorial, we will learn to use the cin object to take input from the user, and the cout object to display output to the user with the help of examples.

➤cin:  cin object to take input from the user.

➤cout: cout object to display output to the user.

Example 1: String Output.

#include <iostream>

using namespace std;

int main() 

{

    cout << "This is C++ Programming";

    return 0;

}

OutPut: This is C++ Programming.

Hints: prints the string enclosed in double-quotes.

Example 2: Numbers and Characters Output.

#include <iostream>

using namespace std;

int main() 

{

    int number1 = 50;

    double number2 = 256.783;

    char ch = 'B';

    cout << number1 << endl;    // print integer

    cout << number2 << endl;    // print double

    cout << "character: " << ch << endl;    // print char

    return 0;

}

OutPut: 

50

256.783

character: B
