Description

You are going to write a complete C program which implements the following functionality:

• Your program will read two input files:

– values.txt – polynomial.txt

• Your program will create a file: – txt
• Your program will evaluate the same polynomial for each value read from _txt and write the results to evaluations.txt

values.txt

This file holds double numbers separated by whitespace.

12.5 5 67.89 -6 -13.37

There may be as many as ₁₀₀ double numbers in this file. polynomial.txt

This file holds a polynomial in a character array form.

5x+23.5x^3-x^2

There will only be one polynomial expression. monomials are not ordered according to the powers of the variable x. The coefficient of x at each monomial is written before the character _x. Powers of x is represented by character _ˆ followed by a number. Each monomial will certainly include a character _x. The length of a polynomial expression can reach up to ₁₀₀₀ characters. evaluations.txt This file will hold the results of polynomial evaluations for each value read from _values.txt. If your polynomial string is _{5x+23.5xˆ3-xˆ2}, set _x to be the value(one of the numbers read from values.txt) and evaluate the mathematical expression: _{evaluation = 5*x + 23.5*x*x*x – x*x}. For the given example above, evaluations.txt will be as follows:

45804.69

2937.50

7349081.25

-5142.00

-56410.13

Remarks:

• In order to convert char arrays to numbers, you can use function _sscanf() which is defined in _<stdio.h>. For example:

double d1,d2; char a[] = “12.5 63.4” sscanf(a, “%lf%lf”, &d1, &d2);

/* d1 stores 12.5 and d2 stores 63.4 */

• In order to find powers of a number, you can use _pow() function defined in _<math.h>

Turn in:

• Source code of a complete C program. Name of the file should be in this format: _{<full_name>_<id>.c}.
• Example: _c. Please do not use any Turkish special characters.
• You don’t need to use an IDE for this assignment. Your code will be compiled and run in a command window.
• Your code will be compiled and tested on a Linux machine(Ubuntu). GCC will be used.
• Make sure that your program does not require specific encodings/markings/line-ending-chars. Make sure it works with a file created in a linux environment.
• Make sure you don’t get compile errors when you issue this command : _{gcc <full_name>_<id>.c}.
• A script will be used in order to check the correctness of your results. So, be careful not to violate the expected output format.
• Provide comments unless you are not interested in partial credit. (If I cannot easily understand your design, you may loose points.)
• You may not get full credit if your implementation contradicts with the statements in this document.
