C Conditional Statement: Exercise-9 with Solution

Write a C program to accept a coordinate point in a XY coordinate system and determine in which quadrant the coordinate point lies.

Pictorial Presentation:

Find the quadrant in which the coordinate point lies

Sample Solution:

C Code:

#include <stdio.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);

}

Sample Output:

Input the values for X and Y coordinate : 7 9                                                                 
The coordinate point (7,9) lies in the First quandrant.

C Programming: Tips of the Day

Static variable inside of a function in C

The scope of variable is where the variable name can be seen. Here, x is visible only inside function foo().

The lifetime of a variable is the period over which it exists. If x were defined without the keyword static, the lifetime would be from the entry into foo() to the return from foo(); so it would be re-initialized to 5 on every call.

The keyword static acts to extend the lifetime of a variable to the lifetime of the programme; e.g. initialization occurs once and once only and then the variable retains its value - whatever it has come to be - over all future calls to foo().
