Solver of quadratic equation

This program is the first task of ISP RAS course C/C++ by I. R. Dedinsky

Structure

• Main project
  • src/
    • solver_quadratic_equation.c
    • equation_lib.c
• Test project
  • tests/
    • tests_from_file.c
    • tests.c
    • test_lib.h
• File with tests
  • file_test.txt

Run

To run main program

cmake .
make
./quadratic_equation

To run tests

cmake .
make
./tests

To run tests with data from .txt

• The line of test.txt looks like a b c roots x1 x2
• roots = -42 means overflow, roots = -1 means infinite number of roots (value of x1 and x2 do not matter), if roots = 0 then x1 = -1 x2 = -1
• example -1 -2 15 2 3.0 -5.0 or 1.79769e+308 1.79769e+308 1.79769e+308 -42 0.0 0.0
• example for liner 0 1 0 1 0 0 or 0 3 -9 1 3 0

cmake .
make
./tests_from_file

or To run tests from test_lib.h

cmake .
make
./tests
