std:cin and std:cout are the standard console input and output streams, respectively. By default, input is redirected from the console keyboard and output redirected to the console screen. However, both streams can be redirected from the command line. This not only allows input and output to be redirected from disk files but also permits the output of one program to be redirected as input to another, allowing two or more programs to be chained together (assuming the output of one program is in the exact format required as input to the next).

Can cin and cout be used in the function definition of user defined functions in C plus plus?
The cin and cout entities (they are not statements) are C++ iostream library objects that allows access to "standard input" and "standard output". In C++, the statement cout > variable; allows reading from standard input to a variable.

#include<iostream.h> void main() { int l,b,h,v; cout<<"Enter length "; cin>>l; cout<<"Enter breadth "; cin>>b; cout<<"Enter Height "; cin>>h; v=l*b*h; cout<<"Volume is "<<v; }
Two numbers are input through the keyboard into two locations C and D write a program in c to interchange the contents of C and D?
#include<iostream.h> main() { int C,D,E; cout<<"Number at location C="; cin>>C; cout<<"Number at location D="; cin>>D; E=C; C=D; D=E; cout<<"New Number At Location C="<<C<<endl; cout<<"New Number At Location D="<<D<<endl; }
How do you use cin in C plus plus?
The class cin is an iostream class that abstracts stdin, allowing you to read from the stdin (console input) file. For instance: int age; cout << "How old are you? "; cin >> age; cout << "You said you were " << age " years of age " << endl;
Write a program to add two numbers using oop?

What is the significance of cin and cout operators in c plus plus?
cin and cout are not operators, they are objects. cin is console input while cout is console output (explicitly idintified as std::cin and std::cout). In other words they are the C++ standard library stream objects that represent stdin and stdout respectively. The corresponding std::cerr stream represents stderr, the console error stream. std::cerr is typically directed to the screen while std::in and std::cout are also typically directed to the screen but can be redirected via the command line when executing the binary executable.
