Write a C program

write a function in ANSI C that compute both roots of a quadratic equation

int solve(double a, double b, double c, double *root1, double *root2) that solve ax^2+bx+c=0, using solution (-b+ - sqrt(b^2-4ac)/2a

function solve should return either 2(two root were found), 1(one root was found) , 0(no roots were found). need not check for overflow. If one one root is found, it should be returned in root1. you may assume that a is not 0.

write a testing function tester(double a, double b, double c, char *msg)

that calls your solve() function and prints out the result along with the ms passed as arguent. tester should only printout the correct number of roots.

write a main function that tests your code above. main function should at least call

tester(1.0,0.0,4.0,"no solution");

tester(1.0,0.0,-4.0,"two solution");

tester(1.0,0.0,0.0,"one solution");

note: the sqrt() function is defned in the math library (include file and library -lm
