C Exercises: Find the quadrant to which a coordinate belongs

C Basic Declarations and Expressions: Exercise-37 with Solution

Write a C program to read the coordinate(x, y) (in Cartesian system) and find the quadrant to which it belongs (Quadrant -I, Quadrant -II, Quadrant -III, Quadrant -IV).

Note: A Cartesian coordinate system is a coordinate system that specifies each point uniquely in a plane by a pair of numerical coordinates.
These are often numbered from 1st to 4th and denoted by Roman numerals: I (where the signs of the (x,y) coordinates are I(+,+), II (−,+), III (−,−), and IV (+,−).

Sample Solution:

C Code:

#include <stdio.h>
int main() 
{
	int x, y;
    printf("Input the Coordinate(x,y): ");
	printf("\nx: "); 
    scanf("%d", &x);
    printf("y: ");
    scanf("%d", &y);
    
		if(x > 0 && y > 0) 
		{
			printf("Quadrant-I(+,+)\n");
		} 
		else if(x> 0 && y < 0) 
		{			
		   	printf("Quadrant-II(+,-)\n");
		} 
		else if(x < 0 && y < 0) 
		{
				printf("Quadrant-III(-,-)\n");
		} 
		else if(x < 0 && y > 0) 
		{
			printf("Quadrant-IV(-,+)\n");
		}
	return 0;
}

Sample Output:

Input the Coordinate(x,y):                                             
x: 25                                                                  
y: 15                                                                  
Quadrant-I(+,+)

Previous: Write a C program to read a password until it is correct. For wrong password print "Incorrect password" and for correct password print "Correct password" and quit the program. The correct password is 1234.
Next: Write a program that reads two numbers and divide the first number by second number. If the division not possible print "Division not possible".
