Question

Purpose : This program calculates the number of roots of a quadratic
         equation. When the discriminant of a quadratic equation is negative
         there is no real root, if zero one real root, if positive two real
         roots exist for the quadratic equation.

Function prototypeof discriminant function

int main()
{
    //local variables
    float a, b, c;  //coefficient variables from formula
        float disc;     //stores the discriminant of the equation

    //Program starting
    cout <<" Program starting.... ";

    //Read values in order of a, b, c
    cin >>a >>b >>c;

    // compute discriminant
        Call the functiondiscriminant,and assign the returned value into the variable disc.

    cout << "The value of the discriminant is "

Explanation / Answer

please rate - thanks #include #include #include using namespace std; float discriminant(float,float,float); int main() {     //local variables     float a, b, c; //coefficient variablesfrom formula         floatdisc;     //stores the discriminant of theequation     //Program starting     cout b >>c;     // compute discriminant        disc=discriminant(a,b,c);     cout
