A company needs to develop a strategy for Software Product development for which it has a choice of two programming language $${L_1}$$ and $${L_2}$$. The number of lines of code $$(LOC)$$ developed using $${L_2}$$ is estimated to be twice the $$LOC$$ developed with $${L_1}$$ the product will have to be maintained for five years. Various parameters for the company are given in the table below.

Total cost of the project includes cost of development & maintenance. What is the $$LOC$$ for $${L_1}$$ for which the cost of the project using $${L_1}$$ is equal to the cost of the project using $${L_2}$$

A
$$4000$$
B
$$5000$$
C
$$4333$$
D
$$4667$$

The following is comment written for $$a$$ $$c$$ function. This function computes the roots of quadratic equation. $$a{x^2} + bx + c = 0$$ the function stores two real roots in $${}^ * root1\,\,\& \,\,{}^ * root2\,\,\,\&$$ returns the status of validity of roots. In handles four different kinds of cases
$$i)$$ When coefficient $$a$$ is zero or irrespective of discriminate
$$ii)$$ When discriminate is positive.
$$iii)$$ When discriminate is zero
$$iv)$$ When discriminate is negative

Only in cases $$(ii)$$ & $$(iii)$$ the stored roots are valid Otherwise $$0$$ is stored in the roots the function returns $$0$$ when the roots are valid & - $$1$$ otherwise. The function also ensures root $$1$$ $$> =$$ root $$2.$$

int get QuadRoots(float a, float b, float c, float $${}^ * root1$$, float $${}^ * root2$$);
