1041 Coordinates of a Point

URI Online Judge | 1041

Coordinates of a Point

Write an algorithm that reads two floating values (x and y), which should represent the coordinates of a point in a plane. Next, determine which quadrant the point belongs, or if you are over one of the Cartesian axes or the origin (x = y = 0).

If the point is at the origin, write the message "Origem".

If the point is over X axis write "Eixo X", else if the point is over Y axis write "Eixo Y".

Input

The input contains the coordinates of a point.

Output

The output should display the quadrant in which the point is.

Solution:

#include <stdio.h>

int main()
{
        double a,b;
    scanf("%lf %lf",&a,&b);

        if(a==0 && b==0)
            printf("Origem\n");

        else if(b==0)
            printf("Eixo X\n");

        else if(a==0)
            printf("Eixo Y\n");

        else if(a>0 && b>0)
            printf("Q1\n");

        else if(a<0 && b>0)
            printf("Q2\n");

        else if(a<0 && b<0)
            printf("Q3\n");
        else
            printf("Q4\n");

 return 0;
