There is no difference; C++ is pretty much whitespace
agnostic. What depends is its use:

int function(int &r)
{
...
}

is a function declaration that accepts an integer pointer as
a parameter, and:

int a = 7;
int &r = a;

will make a reference to an integer.

The spacing around the & makes no difference.

Ask the user to input three positive integers M, N and q. Make the 2 dimensional array of integers with size MxN, where all the elements of I (I = 1,…,M) line will be members of geometrical progression with first element equal to the number of line (I) and denominator q.
