25. Data Structures Using C++25 istream_iterator Used to input data into a program from an input stream General syntax: istream_iterator isIdentifier(istream&);

26. Data Structures Using C++26 ostream_iterator Contains the definition of an output stream iterator General syntax: ostream_iterator osIdentifier(ostream&); or ostream_iterator osIdentifier(ostream&, char* deLimit);

27. Data Structures Using C++27 Programming Example: Grade Report (Input) A sample input file follows: 345 Lisa Miller 890238 Y 4 Mathematics MTH345 4 A Physics PHY357 3 B ComputerSci CSC478 3 B History HIS356 3 A. InputA file containing the data in the form shown previously. Assume the name of the input file is ch4_GradeData.txt and is on floppy disk A.

28. Data Structures Using C++28 Programming Example: Grade Report (Output) The desired output for each student is of the following form: Student Name: Lisa Miller Student ID: 890238 Number of courses enrolled: 4 Course No Course Name Credits Grade CSC478 ComputerSci 3 B HIS356 History 3 A MTH345 Mathematics 4 A PHY357 Physics 3 B

29. Data Structures Using C++29 Programming Example: Grade Report Course Component –Set the course information –Print the course information –Show the credit hours –Show the course number –Show the grade
