write a c++ program that reads the x,y coordinates of a point. Then you program should determine wither this point lies inside a circle with radius equal 5 and centered at the point (1,2) or not.

Try:

#include
#include
#include

using namespace std;

int main()
{
int x, y, sumSquares;
double distance;

cout << "Enter x coordinate : ";
cin >> x;

cout << "Enter y coordinate : ";
cin >> y;

/*
If the distance from the entered point to the midpoint of the circle is less
than or equal to 5, then the point is within the circle.
*/

sumSquares = (x - 1) * (x - 1) + (y - 2) * (y - 2);
distance = sqrt((double)sumSquares);
if (distance <= 5.0)
{
cout << "The point is within the circle" << endl;
}
else
{
cout << "The point is outside the circle" << endl;
}

system("pause");
return 0;
}
