Description
Create a class Matrix to represent an N * N matrix.
Provide public member functions that perform or derive:
1) Matrix(const Matrix &); // copy constructor
2) Matrix &clockwise90();
Rotate a Matrix by 90° clockwise.
NOTE:
If a is a Matrix, the result of a.clockwise90() should be stored back into a. Remember to return the object itself for the use of operation concatenation, such as a.clockwise90().clockwise90(). (You can refer to member function “Matrix &operator=” in function.h.)
3) Overload the stream extraction operator (>>) to read in the matrix elements.
4) Overload the stream insertion operator (<<) to print the content of the matrix row by row.
5) Default constructor
6) Destructor
7) Overload the operator (=) to assign value to matrix.
Note that all of the integers in the same line are separated by a space, and there is a new line character at the end of each line.
Note:
1. This problem involves three files.
- function.h: Class definition of Matrix.
- function.cpp: Member-function definitions of Matrix.
- main.cpp: A driver program to test your class implementation.
You will be provided with function.h and main.cpp, and asked to implement
2. For OJ submission:
Step 1. Include function.h into function.cpp and then implement your function.cpp. (You don’t need to modify function.h and main.cpp)
Step 2. Submit the code of function.cpp into submission block.
Step 3. Check the results and debug your program if necessary.
Input
The first line has an integer N (1<=N<=50), which means the size of the matrix. The total number of elements in the matrix is thus N * N.
For the next N lines specify the elements of the matrix a. All of the integers in the same line are separated by a space.
Output
Your program should print the corresponding results followed by a new line character.
