intro c++ class and only using and using namespace std; to write program.

I write a C++ program to solve a quadratic equation ax 2+bx +c=0 Use the discriminant b2-4ac to determine the type of the solutions and an if-else statement to select the solutions for each type. - 1 solution, 2 real solutions, 2 imaginary solutions. Your code must solve regardless of types of solutions. 2. Write a program that uses a while-loop to calculate the factorial of and integer
