Problem :

Coordinates of a Point

Adapted by Neilor Tonin, URI  Brazil

Timelimit: 1

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.

Sample Input	Sample Output
4.5 -2.2	Q4

0.1 0.1

Q1

0.0 0.0

Origem

Solution:

#include<stdio.h>

 

int main()

{

float  a,b;

                       while(scanf("%f %f",&a,&b)==2){

 

                       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;
