I use Xcode 3. If you are using the same program you can select "view > message bubbles > all issues" from the top menu and they will be displayed. If you are using a different program you should look through its view menu (or something similar) and try to find something about displaying messages.

But what if that number that you are square rooting is a variable, regardless if its an integer or not, and you want to continue to use the square rooted number with more addition before showing it on screen? I am trying to make a C++ program for finding the Surface Area of a Cone and I have to continue to use the number after it is square rooted. Any help?

How do you get the options to pop up after you double click the cmd (pow, sqrt, etc) with the open brackets "double"? I dont get open brackets when I type pow or sqrt.

Can someone tell me what program he's using ?

YouTube wont let me write proper code in the comments, so here is what you can write (minus the semicolons)

double x
cout << "Please enter a number: "
cin << x
cout << "The square root of " << x << " is " << sqrt(x) << endl

the output will be:

Please enter a number: 9
The square root of 9 is 3

I had no idea I had to include cmath. That's what was missing for me. First year computer science student here.

what IDE do you recommend for C++ coding on a mac? I am using Xcode but tbh it sucks :/

[bijansanchez]

[icebergmike]

I have got a problem, when I try to calculate a square root, if the result contains decimals, It shows me the closest number, and not the result with decimals

Hello mine is not doing square root for numbers which are declared in variables
