How to pass two-dimensional array as an argument?

Question

My Matrx class is defined as

class Matrx
{
 double A[50][50];
 int m,n;
public:
 Matrx(void);
 Matrx(int a, int b)
 {
  m=a;
  n=b;
 }
 Matrx o         


        

Answer 1

You can to specify all dimensions or only last dimension to pass an array:

void Matrx::readMatrx(double a[][50])
{
 for(int i=0;i< m;i++)
  {
   for(int j=0;j< n;j++)
    A[i][j]=a[i][j];
  }
}
