How to run C++ program directly from compiler?

Today, we will be learning on how to run a C++ program directly from compiler.So let's start.

Hit cmd + space and type terminal,

Now, hit enter.

I will be running a simple hello world program named hello.cpp placed on my desktop.
So, first of all change the directory to Desktop.

Now, type g++ <filename.cpp> -o <filename>
and hit enter

If the file is with no errors, it will do nothing otherwise give you details about the error.
Now, type ./<filename> like this and your program will run in the same terminal window.

Otherwise you can check the current directory and find a file named <filename.exec>. Hit enter to run directly.

Thank you for reading. Keep coming for more. Don't forget to like and share ;). Videos in progress.

After exiting spotlight will rebuild index and your disk utility will show correct size of the drive and all. Thanks for reading. keep coming for more. Don't forget to share and like ;). Vide...

Quadratic Equations: Made Easier for JEE

Quadratic Equation lesson 2 In the previous lesson we learned on how to solve an equation. We found three methods to solve the equation. If not visit http://scipsycho.blogspot.in/2016/08/quadratic-equations.html Now, we will go into details about quadratic equation, the importance of parameter a, b and c and other things that are important for JEE aspirants. Let's begin. As we saw earlier, a quadratic equation can be represented by ax 2 + bx +c =0. Let's start with 'a'. 1.) Coefficient of x 2 Case 1. : when a < 0 let's inspect the graphical form of the equation. If x -> ∞, only the x 2 term will decide the outcome of the expression as it's magnitude will overwhelm the other factors. Now, as x -> ∞ the value of expression will tend to infinity if a>0. However, a is less than zero therefore, the expression will tend to -∞. when x -> - ∞, x 2 -> ∞, and thus even then the expres...
