Question

Write a program that takes the x, y coordinates of a point in the Cartesian plane and prints a message telling either which axis the point lies on or the quadrant in which it is found.

$image?w=197&h=186&rev=74&ac=1$

Sample Output

(-1.0, -2.5) is in quadrant 3

(0.0, -4.8) is on the y-axis

IN C CODE PLEASE! (NOT C++)

Answer 1

#include <stdio.h>
#include <math.h>

struct Point     //structure
{
   float x;
   float y;
};


   int quadrant(struct Point p) //quadrant function to determine the quadrant in which point lies
   {
       if( p.x>0 && p.y>0)
       return 1;
       else if(p.x<0 && p.y>0)
       return 2;
       else if(p.x<0 && p.y<0)
       return 3;
       else if(p.x>0 && p.y<0)
       return 4;
       else
       return 0;
    
   }

int axis(struct Point p) //axis function to determine on which axis point lies
{
if(p.x == 0)
return 1;
else if(p.y == 0)
return 2;
else
return 0;

}

   int main()
   {
       struct Point p1 = {-1.0, -2.5};
       struct Point p2 = {0.0, -4.8};
     
       printf("(%.1f,%.1f) is in quadrant %d",p1.x,p1.y,quadrant(p1));
     
       printf("\n");
       if(axis(p2) == 1)
       printf("%.1f,%.1f is on y axis",p2.x,p2.y,axis(p2));
       else if(axis(p2) == 2)
       printf("%.1f,%.1f is on x axis",p2.x,p2.y,axis(p2));
     
       else
       printf("\n");
     
      return 0;
   }

Output:

(-1.0, -2.5) is in quadrant 3

(0.0, -4.8) is on the y-axis
