c++ new double array code example
Example: declaring 2d dynamic array c++
int** arr = new int*[10]; // Number of Students
int i=0, j;
for (i; i<10; i++)
arr[i] = new int[5]; // Number of Courses
/*In line[1], you're creating an array which can store the addresses
of 10 arrays. In line[4], you're allocating memories for the
array addresses you've stored in the array 'arr'. So it comes out
to be a 10 x 5 array. */
