C program to find in which quadrant the coordinates lie.

Problem

Write a program to find the quadrant in which the given coordinates lie.

User has to enter a coordinate at runtime and we need to find the quadrant in which these coordinates lie.

Solution

• If both numbers are positive then, it displays the first quadrant.

Example: Input =2, 3 Output = 1st quadrant

• If the first number is negative and the second number is positive then, it displays the second quadrant.

Example: Input = -4, 3 Output= 2nd quadrant

• If the first number is negative and the second number is also negative then, it displays the third quadrant.

Example: Input = -5,-7 Output= 3rd quadrant

• If the first number is positive and the second number is negative then, it displays the fourth quadrant.

Example: Input = 3,-5 Output = 4th quadrant

Example

Following is the C program to find the quadrant in which the given coordinates lie −

 Live Demo

#include <stdio.h> int main(){    int a,b;    printf("enter two coordinates:");    scanf("%d %d",&a,&b);    if(a > 0 && b > 0)       printf("1st Quadrant");    else if(a < 0 && b > 0)       printf("2nd Quadrant");    else if(a < 0 && b < 0)       printf("3rd Quadrant");    else if(a > 0 && b < 0)       printf("4th Quadrant");    else       printf("Origin");    return 0; }

Output

When the above program is executed, it produces the following output −

Run 1: enter two coordinates:-4 6 2nd Quadrant Run 2: enter two coordinates:-5 -3 3rd Quadrant
