c++ Stream objects

The ‘cout’ C++ Stream Object:

The cout is pronounced as See Out. The cout stands for console output. The cout is a c++ standard output C++ stream object. It is used as an output statement to display.

Output on the computer screen. This C++ stream object represents the flow of data from computer memory to display screen. It is a part of iostream.h header file.

c++ Stream objects

The general syntax of cout is as follows:

cout<<const1/var1/exp1[<<consta2/var2/exp2/….];

where

cout:

it is the name of output C++ stream object, which is used to display the standard output.

<<:

It is known as insertion operator or put to operator. It sends the output (contents of variable or constant) to the cout object. The cout object then sends the output to the display screen. We can use multiple insertion operators to display the valued of multiple variables or constants.

Const1/var1/exp1, Const2/var2/exp2:

It indicates the list of constants, variables or arithmetic. Expression. for each constants, or variable or expression. separated insertion operator (<<) is used. The string constant is given in double quotation marks. Character constant is given in singe quotation marks. However, variables, numeric constants and expression are given without quotation marks.

Examples:

Following statement will display a message “Programming Digest”:

Cout<<”Programming Digest”;

This output statement consists of only one string constant which is to be displayed on the screen. This string constant is given in double quotation marks.

Following statement will display the value of variable ‘sum’ on the screen.

cout<<sum;

Please note that in this output statement the variable ‘sum’ is not enclosed with any quotation marks.

Following statement uses one variable “km”, two string constants, one arithmetic expression and four insertion operators:

cout<<km<<” kilometers= “<< km*1000<<”meter”;

Suppose the value of km is 6. The output of the above output statement will be:

3 kilometers= 3000

cout Programming Examples:

C++ Programming Example 17: write a program that computes and display the area of a square. The formula to compute the area of square is using cout stream object:

Area = height * width;

Flowchart:

c++ Stream objects

#include <iostream>
using namespace std;

int main()
{
int height, width, area;
height = 15;
width= 3;
area = height * width;
cout<<"Area of square ="<<area;

}

#include <iostream>

using namespace std;

int main()

{

int height, width, area;

height = 15;

width= 3;

area = height * width;

cout<<"Area of square ="<<area;

}

c++ Stream objects

It the above program “Area of square =” is a text message. The text message will be displayed first and the value of variable ‘area’ will be displayed.

C++ Programming Example18: write a program that adds two floating point values and displays the sum on the screen using cout stream object:

#include <iostream>
using namespace std;

int main()
{
   float a, b,s;
   a=20.3;
   b=50.2;
   s=a+b;
