The above answer is true. Namespace works with g++ and vc++
compilers. These are newly created standard library files of
c++. But the namespace doesn't work for turbo c++.
Actually 'namespace std' creates a kind of space for
standard library files to be stored in it. The earlier
extension of '.h' or header files is now not used in c++.

Describe these concepts: Polymorphism, Inheritance and Abstraction.

They started with the brief introduction followed by few basic C++ questions on polumorphism, inheritance and then virtual functions. What is polymorphims? How you will access polymorphic functions in C? How virtual function mechanism works?

Write a program to compute for numeric grades for a course. The course records are in a file that will serve as the input file. The input file is in exactly the following format: Each line contains a student's first name, then one space, then ten quiz scores all on one line. The quiz scores are in whole number and are separated by one space. Your program will take it input from this file and sends it output to a second file. The data in the output file will be exactly the same as the data in the input file except that there will be one additional number (of type double) at the end of each line. This number will be the average of the student's ten quiz scores. Use at least one function that has file streams as all or some of its arguments.
