In this article, we will discuss the unformatted Input/Output operations In C++. Using objects cin and cout for the input and the output of data of various types is possible because of overloading of operator >> and << to recognize all the basic C++ types. The operator >> is overloaded in the istream class and operator << is overloaded in the ostream class.

The general format for reading data from the keyboard:

cin >> var1 >> var2 >> …. >> var_n;

• Here, var1, var2, ……, varn are the variable names that are declared already.
• The input data must be separated by white space characters and the data type of user input must be similar to the data types of the variables which are declared in the program.
• The operator >> reads the data character by character and assigns it to the indicated location.
• Reading of variables terminates when white space occurs or character type occurs that does not match the destination type.
