Chapter 7.12, Problem 7.34CP
Program Plan Intro
Structure:
In C++, the structure is a user-define data type, which contains different type of elements with different lengths.
- The size of the structure is calculated by the total number of elements which is declared in a structure.
- Structure can be passed as a function argument in the same way as pass any other variable.
- It can also be passed as a reference variable in a function argument.
- A structure can be returned by a function as a structure variable.

- C++ Coding Write a program that asks a teacher to enter the student's and the grades received on her quarterly exams. The datatype for the student's name could be a string and the four grades should be entered in an array of data types int. Test scores are on the base of 100. The main() functions describe the average function with the following title line: double avg( int grades[] , int cap ): The program prints the student's name, her four grades, and her average grades.
