Write and test a program that solves quadratic equations. A quadratic equation is an equation of the form ax2+ bx + c =0 ,where a,b and c are given coefficient and x is the unknown The coefficients are real number inputs ,so they should be declared of type float or double Since quadratic equations typically have two solutions ,use x1 and x2 for the solutions to be output These should be declared of type double to avoid inaccuracies from round-off error

hi there. I have noticed that in the lesson you didn't gave the int datatype a size parameter. Does it mean that int parameter can hold lby default any integer no matter how many characters it consists of?

I recently created and saved a small program privately and now I cannot figure out how to open it to edit and run it. I am new to using this app to create and run Java programs and would like to know how to do this in order to edit and reuse my programs. How do I open a program I have privately saved?

How exactly do I access the files I saved in the code playground? Do you have to make them public in order for them to save? Since I've been trying to save things, but I can't find where they show up. Thanks.

when adding a pointer in any main body like a inventory displayer , does it matter about the order of placement? Is it necessary to have " return 0;" at the end of it if or is it included with original maroon body? thanks in advance!

When I get to the console application part and put in the project name etc.. once I hit next it does not continue and I basically get a failed message. I assume because I'm using a mac and it does not have a c drive. What's the work around?

i want to write a line of code that looks like this if (a>10){ I know that in c++, you cannot just have greater than (>) or less than (<). j it must be (>=) or (<=). But the code I need to write does not include the equal to(=). it just has to be greater than 10. What do I do?

I have 10 variables called, int1, int2, int 3 and so on. The user can write one number into the console. If the user types 7, I want to add 3 to the value of int7. how do I do this without 10 if statements? can I somehow do something like, (int + "userinput") += 3? thank you for your help! :D

I will like to ask this question, but I don't know if is beyond the scope of this learning. it's about Gethashcode (), Tostring () Gettype () etc. I will like a little enligthment. The definition and overriding in a class, though I have gotten some definition, but I will like if someone could throw more light on it's usage.

so far in section 1 question 2 area all of the videos have been ads that if you skip the add it just brings up the questions you need to answer. also if you play the add all the way thru you get the same exact thing. luckily I'm using this as a refresher course but I would think if I didn't know anything about c++ then I could be pretty lost missing videos.

Write a program that uses a dynamic array that contains 5 items of double values. The size of the array is entered when the program is run. Aldo the 5 values must be entered. These tasks are done in the main ( ) function. Then write a function to display the 5 values. The function must have a pointer variable as a parameter. The function is called from the main ( ).
