Explanation:
Linux operating system is a fast open-source computer platform for programmers and network administrators. Its system is arranged in a hierarchical tree structure with the root represented as "/" (for absolute path).
The passwd is a folder in the Linux OS that holds the login details of all users in the system network. The 'awk' is one of the commands used to get information from a file in a folder. It prints out the result by specifying the location of the values (like the username and user id) as a variable (with prefix '$') and then the target folder.
Answer
Making a video game is much less daunting than it might seem. While you likely aren’t going to go from having no experience to making the next Grand Theft Auto, it has actually never been easier to get started making games. Game development tools and resources have become increasingly accessible to the average person, even if they have no programming experience. Often these tools are also available for free.
To try to make things easier for those looking to get started making games, we’ve put together a list of 11 game engines / editors. Some are designed for a specific genre of game or to be incredibly easy for newcomers. Others are professional development tools for AAA games, but are effectively free to use for hobbyists and still offer a lot of learning tools to help those with limited programming experience get started.
There are, of course, a lot of things that go into game development — music, animation, sound, writing, texturing, modeling, etc. — however, the game engine / editor you choose is going to have the biggest effect on what kind of game you can make. If you have suggestions for other engines, software, or learning tools for the other aspects of development, post it in the comments.
Answer:
ALTER TABLE Products
ADD Products_price float(5,2) DEFAULT 9.99,
ADD Adding_time datetime;
Explanation:
So at first we need to use ALTER TABLE statement, when we use this statement we also need to provide the table name. In this case, i assume it is 'Products'.
Then, as per question, we need to add two columns.
The first one is 'product_price' and it contains decimal points. So, we need to use ADD statement and give a column name like 'Prodcuts_price' and its datatype 'float' because it contains decimal or floating points. so, for 3 digits on the left and 2 digits on the right, it makes a total of 5 digits. So, we need to declare it like this. (5,2) it means a total of 5 digits and 2 after the decimal point. after that, we need to set our Default value using the DEFALUT statement. so DEFAULT 9.99. it will set the default value to 9.99 for existing products.
And for our next column, we give its a name like 'Adding_time' then it's datatype 'datetime' because it will contain date and times.
If you want your heading to pop out I would go for bold Becuase it shows the letters darker and bigger which would make the heading the center of attention.
