coordinate point in a XY coordinate system and determine

#include <stdio.h> #include<stdlib.h> void main() {   int co1,co2;   printf("Input the values for X and Y coordinate : ");   scanf("%d %d",&co1,&co2);   if( co1 > 0 && co2 > 0)   printf("The coordinate point (%d,%d) lies in the First quandrant.\n",co1,co2);   else if( co1 < 0 && co2 > 0)   printf("The coordinate point (%d,%d) lies in the Second quandrant.\n",co1,co2);   else if( co1 < 0 && co2 < 0)   printf("The coordinate point (%d, %d) lies in the Third quandrant.\n",co1,co2);   else if( co1 > 0 && co2 < 0)   printf("The coordinate point (%d,%d) lies in the Fourth quandrant.\n",co1,co2);   else if( co1 == 0 && co2 == 0)   printf("The coordinate point (%d,%d) lies at the origin.\n",co1,co2);     }

Simple output :

Input the value for X nd Y coordinate 7 9
the coordinate point (7 & 9) in the First quandrant.
