If/Else Statements

Question

I'm trying to use if/else statements with the discriminant formula, b^2-4ac to print out the number of solutions and to print out the actual answers. rootCount in my main is saying that rootCount needs a pointer-to.

#include<iostream>
#include<string>
using namespace std;

double rootCount(double a, double b, double c);
double d1(double a, double b, double c);
double d2(double a, double b, double c);

int main(void)
{
double a, b, c, d;
double rootCount;

cout << "Program uses the discriminant, b^2-4ac, to determine the number and type of roots." << endl;
cout << "Enter a: ";
cin >> a;
cout << "Enter b: ";
cin >> b;
cout << "Eneter c: ";
cin >> c;

d = b * b - 4 * a * c;

cout << "The number of solutions is: " << rootCount(a, b, c ) << endl;
cout << "The solutions are: " << d1(a, b, c) << "and " << d2(a, b, c) << endl;
system("pause");
return 0;

}

double rootCount (double a, double b, double c)
{
double d;
d = b * b - 4 * a * c;
if (d > 0) {
cout << "Two solutions" << endl;
}
if (d == 0) {
cout << "One solution" << endl;
}
else {
cout << "No real solutions" << endl;
}
return d;

}

double d1(double a, double b, double c)
{
double d;
d=(b*b - 4 * a*c);
return d;
}
double d2 (double a, double b, double c)
{
double d;
d= -1 * (b*b - 4*a*c);
return d;
}

Answer 1

Now I can actually run the program. When I run the program though, the program prints one of the if statements and the else statement. Also it will say "the number of solutions is: 28." When I really want that number to be printed in "The solutions are: 28 and -28"

Answer 2

I put my if else statements in the main function and it fixed my problem. Thanks for the help.
