I am also hoping for a C++ stuff with operator overloaded.

>>>> I am also hoping for a C++ stuff with operator overloaded
Suppose, you think of overloading unary operator~.
Take the sample sunnycoder gave you a link to.
Make the three functions
double Determinant(double **a,int n)
void CoFactor(double **a,int n,double **b)
void Transpose(double **a,int n)
member functions of a class Matrix. 'a' and 'n' were data members of the class while 'b' needs to be passed as 'Matrx& b'. Determinant, CoFactor and Transpose have no arguments then. The rest of the implementation code should compile with minor changes (e. g. replace malloc/free by new/delete).
Then
Matrix& Matrix::operator~()
{
Matrix b = *this; // make a copy
CoFactor();
Transpose( );
(*this) /= b.Determinant();
return *this;
}
Beside of the three functions you would a copy constructor/assignment operator and a operator/= where the prototype is
Matrix& Matrix::operator/=(double d);
