Is it necessary to use the court function with a switch statement? And does the case value always have to be a number? or can it be a letter or word?

I have an iphone 5s and when I test the code, I see no difference from thick and 700. I also wrote: CSS: .p thickest { Font-size: 900; } Html: <p .thickest>This should be "BOLDEST" </p> And the last 3 were the same size. Could it be the phone or is the code wrong?

Hey there, I don't know why, but when I import tkinter on IDLE like this: from tkinter import * And I say: window = Tk() Even known I use python 3.2.5, which should be able to use Tkinter, the python shell raises a ValueError that says that Tk() is not defined. I am very sure I use python 3.2.5 and tutorials from the Python Foundation say that is what I have to do. But it still doesn't work. Does anyone have an idea of how to solve this problem? Thank you!

While prototyping friend functions in a class is it necessary to always pass the address of the object as parameter?If so why is it that we have to pass address as parameter..In programs involving compositions we never used addresses...Why is the need for address of the objects while using friend?

Just a friendly suggestion: I downloaded the Python Console on Google Play Store, so when I have issues in the app that may be bug related, I can try it in the console. I often can figure it out there more easily. May not be helpful to some, but was for me.

what have i to do, if i want that the program always writes for example : 0+1 1+2 3+3 6+4 10+5 15+6 ... because now it just writes 1 3 6 10 15 ... and maybe if it works, can i make then 0+1=1 1+2=3 3+3=6 6+4=10 #include <iostream> using namespace std; int main(){ int i; int sum = 0; for (i = 1; i <= 100; i++){ sum = sum+i; cout<<sum<<endl; } cout<<sum; return 0; }

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
