polynomial_api

All basic polynomial operations in C. Polynomials are stored as linked lists.

Polynomial operations

• Create polynomial - p = create_poly()
• Read a polynomial string 'str' and convert it into polynomial type p - read_poly(p,str)
• Add two polynomials p1 and p2 - p3 = add_poly(p1,p2)
• Subtract two polynomials p1 and p2 - p3 = subtract_poly(p1,p2)
• Multiply two polynomials p1 and p2 - p3 = multiply_poly(p1,p2)
• Evaluate a polynomial p with a double value val - result = evaluate_poly(p,val)
• Display a polynomial p - display_polynomial(p)
• Delete a polynomial - delete_poly(p)

Files

• polynomial.h - Header file containing all the function prototypes and data structures.
• polynomial.c - The implementation of the polynomial functions.
• test.c - Test file .

Run the code

For compiling and linking both test code and library functions in gcc compiler.

	>	gcc test.c polynomial.c -o polynomial -lm

For running the executable.

	>	./polynomial

For read_poly(), the parsing was done using the concept of context free grammer. -[Erik Jansson] (https://erj.me/post/polynomial_in_c/)
