declaring 2d dynamic array c++

By PYTHON_NOT_SNAKE.pyPYTHON_NOT_SNAKE.py on Sep 18, 2020 
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. */
