You_Are_A_Square
/*A square of squares
You like building blocks. You especially like building blocks that are squares. And what you even like more, is
to arrange them into a square of square building blocks!
However, sometimes, you can't arrange them into a square. Instead, you end up with an ordinary rectangle! Those
blasted things! If you just had a way to know, whether you're currently working in vain… Wait! That's it! You just
have to check if your number of building blocks is a perfect square.
Task
Given an integral number, determine if it's a square number:
In mathematics, a square number or perfect square is an integer that is the square of an integer; in other words,
it is the product of some integer with itself.
The tests will always use some integral number, so don't worry about that in dynamic typed languages.
Examples
is_square (-1) // false
is_square (3) // false
is_square (4) // true
is_square (25) // true
is_square (26) // false

#include <cmath>
bool is_square(int n)

if(((int)sqrt(n)) == sqrt(n)) return true;
else
return false;
