Programming

Description

Define two structured types, one for a two - dimensional Point (floating point coordinates named x and y), the other for a triangle consisting of 3 Points. Have main declare a Triangle and then fill in its vertex Points with random floating point numbers between 0 and 1. Write a second function named centroid with a single input (parameter), a Triangle. The purpose of the centroid function is, surprise, surprise, to compute and return the centroid of a triangle. Have main print out the vertices of the Triangle and then print out the results of the call to centroid.

Centroid of a Triangle Define two structured types, one for a two-dimensional Point (floating point coordinates named x and y), the other for a triangle consisting of 3 Points. Have main declare a Triangle and then fill in its vertex Points with random floating point numbers between 0 and 1. Write a second function named centroid with a single input (parameter), a Triangle. The purpose of the centroid function is, surprise, surprise, to compute and return the centroid of a triangle. Have main print out the vertices of the Triangle and then print out the results of the call to centroid. Here's what my printout looks like: The triangle vertices are [0.69, 0.51], [0.59, 0.55], and [0.38, 0.26] The centroid is [0.55, 0.44] Notes:  When debugging your centroid function, you obviously may use printf as necessary (that's how we debug, right?); but remove all the debugging printf statements from centroid before you turn in your final code. In the final version, only main may call printf to produce the printout shown above.  Use no global variables – this assignment is about passing structures into and back from a function. Note: Global definitions for your structures will be required for this program (why?); but global variables are forbidden.  Don't make the parameter for the centroid function an array, make it a structure (a triangle) – you already know how to pass arrays into functions; the point here is passing and returning structures. You can put an array of 3 Points inside the Triangle structure, if you wish, or use three individually named components (e.g., vertexA, vertexB, and vertexC); it's your call, It will probably be slightly simpler if you put them in an array, called something clever like, say vertex[3], but, as I said, it's your call. But the centroid function itself must be defined as having only a single parameter and that must be a triangle structure. And the value returned by this function must be also be a structured value (but it's a point, not a triangle, obviously). Note: I want the centroid function to return a point as its return value to main; do not have the centroid function produce a side-effect in main --- you know how to do that now (I hope;-) but that's not what I want for this assignment.  You may wish to create a getRandomPoint function that returns a Point and then use that in main to populate the values in the three Points of the Triangle. Like the centroid function, it would return a point, using the return-by-value handling of structs. What to turn in: Upload the typescript file with the following cat –n of your .h file(s) if you used any cat –n of your .c file gcc of your .c file a.out (or whatever you called your executable Upload your .c (and .h files if you created any)
