Count in a loop

Imagine a square with sides of 2 meter. In the centre is point M, at (0,0). We randomly throw darts at this square, which all hit at some location p on the square (uniform distribution). Next, we count the number of ‘hits’. Each dart is a hit when the distance from p to M is less than or equal to 1.

I have this code I dont know how to count the number of p that is less than or equal to 1

for i=1:100;

p_x= -1+(1+1)*rand;

p_y= -1+(1+1)*rand;

p = sqrt((p_x)^2 + (p_y)^2)

end;

"I have this code I dont know how to count the number of p that is less than or equal to 1"

count=0;
for i=1:100
    p_x= -1+(1+1)*rand;
    p_y= -1+(1+1)*rand;
    p = sqrt((p_x)^2 + (p_y)^2)
   if p<=1
   count=count+1;
   end
end
fprintf('The p count is (when p<=1): %d',count);

Thank you so much

N = 100; % no loops needed
p_x= -1+(1+1)*rand(N,1);
p_y= -1+(1+1)*rand(N,1);
p = sqrt(p_x.^2 + p_y.^2);
fprintf('No of times P less than or equal to one:%d',nnz(p<=1))

Yes @Madhan, I haven't noticed that
