A matrix is a two-dimensional array of objects. If, for instance, you wanted a 10 by 20 matrix (array) of doubles, you would say...
double mydoublearray[10][20];
You would then refer to each element with the syntax...
double somedouble;
somedouble = mydoublearray[3][7];
Note that array indices start from zero, and go to the declared size minus one, so the first element is mydoublearray[0][0]and the last element is mydoublearray[9][19].
You can have arrays of elementary types and of classes. The syntax is the same. Just use the class name instead of the word double.

How do you write a program in c plus plus to check if an array is symmetric?
To determine if an array is symmetric, the array must be square. If so, check each element against its transpose. If all elements are equal, the array is symmetric.For a two-dimensional array (a matrix) of order n, the following code will determine if it is symmetric or not:templatebool symmetric(const std::array& matrix){for (size_t r=0 ; r
Is there an answer book for the A plus program?
The A Plus Program is an initiative, not a test. So no, there is no answer book.
Can somebody give me the program to find simple interest using friend function in c plus plus?
Here is an example program: class obj{ public: float p,n,r,si; friend void calc( obj temp); }; void calc( obj temp){ si = (p*n*r)/100; } The initialization and function calling is essential.
