Must be in C language
ECE 272 Organization of Computers Spring 2022ECE 2220 System Programming Concepts1 of 3 Lab 1 – C Review – Plotting a Function Objectives In this lab, each student is to write a program that allows a user to choose a function and plots a primitive graph of that function. The student should show a proficiency in: · Manipulation of arrays · Formatting output · Processing Input · Using Conditionals and loops · Using the Math library Input The program should prompt the user to choose from one of the following functions to graph: · e(x) (exp()) · ln(x) (log()) · sine(x) (sin()) · cosine(x) (cos()) · tangent(x) (tan()) or chose ‘q’ to quit. After choosing the function to display, the user should be prompted for the minimum and maximum value for the range of inputs to the function as a float. The minimum must be less than the maximum and should be checked for. Finally, the user should be prompted for the number of rows and columns to display the output as an integer. The maximums allowed should be fifty rows and two hundred columns. Operation Once the desired function information is input, the program should calculate the values for the function over the input range using floating point numbers, while also keeping track of the minimum and maximum output values produced. The program should then use a two-dimensional array of bins bin[r][c] where the r dimension is equal to the rows value input above and will represent one of r rows which divides the output into r evenly distributed ranges of the output values, and the c dimension is equal to the columns value input above and represents one of c columns which divides the input range into c evenly distributed ranges for the input values. The program will use these values to display a primitive plot of the function. Output The program should output the function being plotted, the minimum and maximum input values, and the minimum and maximum output values. Next, the program should output on each row a row number (in reverse order) along with the minimum value for each row range. Finally, it should also output an ‘x‘ in each column from 1 to columns that represents each input value plotted. The location of each ‘x’ should be in the row which represents the range of outputs each row 1 to rows corresponds to. For example, if the function chosen is the cosine function, the input range is 0 to 10, and the output rows equals 20 and the output columns equals 40 then the outputs would be y[0.000000] = 1.000000 y[0.250000] = 0.968912 y[0.500000] = 0.877583 y[0.750000] = 0.731689 y[1.000000] = 0.540302 y[1.250000] = 0.315322 y[1.500000] = 0.070737 y[1.750000] = -0.178246 y[2.000000] = -0.416147 y[2.250000] = -0.628174 y[2.500000] = -0.801144 y[2.750000] = -0.924302 y[3.000000] = -0.989992 y[3.250000] = -0.994130 y[3.500000] = -0.936457 y[3.750000] = -0.820559 y[4.000000] = -0.653644 y[4.250000] = -0.446087 y[4.500000] = -0.210796 … y[7.500000] = 0.346635 y[7.750000] = 0.103794 y[8.000000] = -0.145500 y[8.250000] = -0.385748 y[8.500000] = -0.602012 y[8.750000] = -0.780846 y[9.000000] = -0.911130 y[9.250000] = -0.984765 y[9.500000] = -0.997172 y[9.750000] = -0.947580 y[10.000000] = -0.839072 where the minimum output is -0.997172 and the maximum output is 1.000000. Therefore, each row represents a range of 0.099859, and the output graph would look like 19:+0.900141 - X XXX 18:+0.800283 - X X X 17:+0.700424 - X X X 16:+0.600565 - 15:+0.500707 - X X X 14:+0.400848 - 13:+0.300990 - X X 12:+0.201131 - X 11:+0.101273 - X 10:+0.001414 - X X 09:-0.098445 - 08:-0.198303 - X X 07:-0.298162 - X 06:-0.398021 - X 05:-0.497879 - X X 04:-0.597738 - 03:-0.697596 - X X X 02:-0.797455 - X 01:-0.897314 - X X X 00:-0.997172 - XXXX XXXX The program should loop continuously asking the user to choose a function, range values, and display columns and rows until a ‘q’ is entered upon which the program terminates. Further Considerations To get full credit, the program’s code should be efficient, use consistent and readable formatting, and contain explicit program, function, block, and line commenting. Work must be completed by each individual student, and only that student. Students must not use code from another student or copied from a book or internet source. Students must not allow other students to copy from their code or make it possible for students to copy theirs by making their code available to be copied. Sharing of code will not be tolerated and will be tested for. Any such act of cheating will result in failing the class and may result in dismissal from the University. Creation and Submission Use the following line to compile your program: gcc p1.c -o p1 -Wall -g -lm The code you submit must compile using the -Wall flag and should have no compiler errors or warnings. To receive credit for this assignment your code must compile and perform some sort of operation. Code that does not compile or crashes before outputting anything will not be accepted or graded. All students must do a final check on one of the CES Ubuntu machines to verify that gcc using Ubuntu shows no warning messages before submitting your project. To get full credit, the program must be submitted on Canvas by midnight Monday, January 24th.
