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.

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
The A Plus Program is an initiative, not a test. So no, there is no answer book.
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.

Yes. Matrix addition is commutative.
for(int i=0;i
It would be no different. Matrix addition is Abelian or commutative. Matrix mutiplication is not.
It is a singular matrix.
It is a singular matrix.
Double it: puts ("Here\\comes\\an\\example"); output: Here\comes\an\example
struct point { int x; int y; };
For example: int main (void) { return 0; }
#include<iostream> int main() { std::cout << "Hello world!" << std::endl; }
