# Program to determine the quadrant of the cartesian plane

Given co-ordinates (x, y), determine the quadrant of the cartesian plane. Image_source : wikipedia.org
Examples :

```Input : x = 1, y = 1
Output : lies in 1st quadrant

Input : x = 0, y = 0
Output : lies at origin
```

## Recommended: Please try your approach on {IDE} first, before moving on to the solution.

There are 9 conditions that needs to be checked to determine where does the points lies –

```If in first quadrant then,    x > 0 and y > 0
If in second quadrant then,   x < 0 and y > 0
If in third quadrant then,    x < 0 and y < 0
If in fourth quadrant then,   x > 0 and y < 0
If in positive x-axis then,   y = 0 and x > 0
If in negative x-axis then,   y = 0 and x < 0
If in positive y-axis then,   x = 0 and y > 0
If in negative y-axis then,   x = 0 and y < 0
If at origin then,            x = 0 and y = 0 ```

Below is the implementation of the above approach :

## C++

 `// CPP program to check quadrant ` `#include ` `using` `namespace` `std; ` ` `  `// Function to check quadrant ` `void` `quadrant(``int` `x, ``int` `y) ` `{ ` ` `  `    ``if` `(x > 0 and y > 0) ` `        ``cout << ``"lies in First quadrant"``; ` ` `  `    ``else` `if` `(x < 0 and y > 0) ` `        ``cout << ``"lies in Second quadrant"``; ` ` `  `    ``else` `if` `(x < 0 and y < 0) ` `        ``cout << ``"lies in Third quadrant"``; ` ` `  `    ``else` `if` `(x > 0 and y < 0) ` `        ``cout << ``"lies in Fourth quadrant"``; ` ` `  `    ``else` `if` `(x == 0 and y > 0) ` `        ``cout << ``"lies at positive y axis"``; ` ` `  `    ``else` `if` `(x == 0 and y < 0) ` `        ``cout << ``"lies at negative y axis"``; ` ` `  `    ``else` `if` `(y == 0 and x < 0) ` `        ``cout << ``"lies at negative x axis"``; ` ` `  `    ``else` `if` `(y == 0 and x > 0) ` `        ``cout << ``"lies at positive x axis"``; ` ` `  `    ``else` `        ``cout << ``"lies at origin"``; ` `} ` ` `  `// Driver code ` `int` `main() ` `{ ` `    ``int` `x = 1, y = 1; ` `    ``// Function call ` `    ``quadrant(x, y); ` `    ``return` `0; ` `} `
