(Geometry: points in triangle?) C++ program

Suppose a right triangle is placed in a plane as shown below. The right-angle point is placed at (0, 0), and the other two points are placed at (200, 0), and (0, 100). Write a C++ program that

prompts the user to enter a point with x - and y -coordinates and determines whether the point is inside the triangle

Here are some sample runs:
Enter a point's x- and y-coordinates: 100.5 25.5

The point is in the triangle

Enter a point's x- and y-coordinates: 100.5 50.5

The point is not in the triangle

Explanation / Answer

Program:

/******************************************************************************

*******************************************************************************/
#include <stdio.h>
#include <iostream>
using namespace std;
int check_point(int x,int y)
{
if( (y > 0) && (x > 0) && (x + 2*y < 200) )
return 1;
else
return 0;
}
int main()
{
float num1,num2;
cout<<"Enter a point's x- and y-coordinates: ";
cin>>num1>>num2;
if (check_point(num1, num2))
cout<<"The point is inside the triangle";
else
cout<<"The point is outside in the triangle";
}

Output:

Enter a point's x- and y-coordinates: 100.5 50.5                                                                      

The point is outside in the triangle   

Enter a point's x- and y-coordinates: 100.5 25.5                                                                      

The point is inside the triangle
