Write a C program to do the following.

• Get an integer x value from the user.
• Get an integer y value from the user.
• Determine the quadrant into which the point (x, y) falls.
• Output the quadrant.

If the requirements are unclear in any way, use any provided input and output to resolve the discrepancy.

See Guidelines for C programs .

Domain knowledge is the background knowledge that is useful in solving a problem, designing a solution, implementing the solution, etc. The following domain knowledge may be useful for this requirement.

In the x-y plane, there are four quadrants.

In the traditional x-y plane, the four quadrants are as follows.

• the upper-right is quadrant 1 (positive x, positive y)
• the upper-left is quadrant 2 (negative x, positive y)
• the lower-left is quadrant 3 (negative x, negative y)
• the lower-right is quadrant 4 (positive x, negative y)

The assumptions for this work are the following.

• the upper-right is quadrant 1 (nonnegative x, nonnegative y)
• the upper-left is quadrant 2 (negative x, nonnegative y)
• the lower-left is quadrant 3 (negative x, negative y)
• the lower-right is quadrant 4 (nonnegative x, negative y)

Note: In addition to specific domain knowledge, you should be familiar with all concepts covered to this point in the course.

Here is a decision tree for this problem.

The following coding examples and/or notes may be of use for this requirement.

• Conditional processing
• C: If examples and refactoring

Make all necessary assumptions. Make no unnecessary assumptions.

In addition to specific coding examples, you should be familiar with all concepts covered to this point in the course.

You are provided with the following starter program in file quadrant.c.

Do not remove any comment that starts with three slashes.

Here is the C code.
/// File: quadrant.c /// Purpose: Quadrant determination /// Author: (your name) /// Help received: // (add here) /// pseudo-code: // (add here) #include <stdio.h> int main() { ///:BEGIN ToDo ///:END ToDo return 0; }
You are to fill in the missing parts of the program according to the work requirements (see above).

In the comments at the top, you are to fill in the author (your name), help received (person and type of help), and pseudo-code parts which are not in the solution (usually provided, but you need to add them). Remove the parentheses too.

Here are some examples of input and output for the above program code.

Here is an example input from file input1.txt.
2 3
For the above example input, here is the expected output.
Enter an integer value for x. You entered 2 for x. Enter an integer value for y. You entered 3 for y. The point (2,3) is in quadrant 1 (one).
Here is an example input from file input2.txt.
-1 2
For the above example input, here is the expected output.
Enter an integer value for x. You entered -1 for x. Enter an integer value for y. You entered 2 for y. The point (-1,2) is in quadrant 2 (two).
Here is an example input from file input3.txt.
-3 -2
For the above example input, here is the expected output.
Enter an integer value for x. You entered -3 for x. Enter an integer value for y. You entered -2 for y. The point (-3,-2) is in quadrant 3 (three).
Here is an example input from file input4.txt.
1 -3
For the above example input, here is the expected output.
Enter an integer value for x. You entered 1 for x. Enter an integer value for y. You entered -3 for y. The point (1,-3) is in quadrant 4 (four).
Here is an example input from file input5.txt.
0 0
For the above example input, here is the expected output.
Enter an integer value for x. You entered 0 for x. Enter an integer value for y. You entered 0 for y. The point (0,0) is in quadrant 1 (one).
Here is an example input from file input6.txt.
0 5
For the above example input, here is the expected output.
Enter an integer value for x. You entered 0 for x. Enter an integer value for y. You entered 5 for y. The point (0,5) is in quadrant 1 (one).
Here is an example input from file input7.txt.
-6 0
For the above example input, here is the expected output.
Enter an integer value for x. You entered -6 for x. Enter an integer value for y. You entered 0 for y. The point (-6,0) is in quadrant 2 (two).

Pseudo-code is a "false" code. It is not really code, but a simplified English explanation that is somewhat similar to code. Pseudo-code is useful for understanding what a program does. For this work, the following can be used as the pseudo-code. Adjust if needed.
Get the input Output the quadrant result
Note: Only some essential details are included. Some details, such as input, prompts, input echo, and obviously needed output are omitted.

The best way to copy-paste pseudo-code that includes indented code (e.g., with tabs) is as follows (in the code file) using a multi-line comment.

It is best to separate input, processing and output into different parts of a program.

Since C has limited string handling capabilities (they can get complex), some processing involving string processing is moved to the output section of the code.

For a two level decision tree, (at least) 2*2= 4 test cases, one for each branched outcome, are needed.

Since most conditions have a boundary, one usually wants to have a test case at and on side of the boundary.

For a two level decision tree, with boundary conditions, (at least) 3*3= 9 test cases, one for each branched outcome, are needed. Note that as the number of possible if branches increase, the number of test cases increase, and it becomes impossible to manually run and test your program with each change.

Automated test methods allow the programmer to automatically run their program against many test cases.
