EXPLAINED ANSWERS FOR IP MID-TERM MODEL QUESTIONS

For the above question, the answer is (c). Let's get answer by answer.

(a) 1020

This answer will be given when we type the following code;


It will be printed in the terminal as follows;


(b)2010

This answer will be given when we type the follwing code;

It will be given in the terminal as follows;



(c)10

We already know the answer of this question is 10. 10 can be given in several ways. In the question we assume that the answer would be 1020. But it isn't. Look at the figures given below. I typed the given example in the vi editor.

As the result of the above code I got the following output.

The above answer will be given by the following code also;
(d)20

20 will be given by following code;
It'll appear in the terminal as follows;

(e) run time error

This can't be correct, refer the answer (c)

For above question the answer is (d) 1. It's a little bit tricky but if you know the precedence order of the operators and arithmetic which are related to the C language it's very simple. First, they've  set some values for the variables.
       x=2
       y=6
       z=6
Then they've made a formula ; x = y == z
According to the precedence order, we have to calculate the value for y == z. As  both of those variables have the same value, that gives 1 as the value of 'y'. If y = 5 and z = 7 , the answer will be 0.
Here, we have to put Boolean rules. 
After that we have to calculate the value for x = y. As we got the answer for y , we have to assign that value to x. So, the answer for x will be '1'. According to the code, we are asked to  display the value of 'x'.

    Fedora 31 Fedora is a linux operating system which shows more paths than windows. So, in programming we are using Fedora as the OS system. Before starting the programming we have to understand the basic codes and basic functions in Ferdora.  01. Opening the terminal - Once you log in to the Fedora, go to the Activities > Menu> Utilities> Terminal                   or Activities>Menu>Search for the Terminal 02. Creating a File- consider typing vi myFirstText.txt and press Enter .  This will create a file named "myFirstText" and the extension  of that file is .txt After creating the .txt file it will take you to the inside of the file. Though you opened the txt file it will not alow you to type until you press the Insert  button. As an example I typed Every person is beautiful . It'll appear as below. When you press the Insert key, it'll appear on the left side of the b...
