Program Plan Intro

Input and Output with files:

C++ programming language provides some classes in order to perform operation using input and output files. By using those classes, data can be written into the file and also they can be retrieved from the file. The classes are as follows:

• ofstream – It is called as output file stream. It is a stream class that is used to write information into the files. Writing data into the file takes place using insertion operator (<<).
  • Syntax: ofstream objectName;
  • Writing data into the file: objectName << variable_Name;
• ifstream – It is called as input file stream. It is a stream class that is used to read data from the files. Reading data from the file takes place using extraction operator (>>).
  • Syntax: ifstream objectName;
  • Reading data from the file: objectName >> variable_Name;
