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:
B. 1 6 3
Explanation:
Given function definition for calc:
void calc (int a, int& b)
{
int c;
c = a + 2;
a = a * 3;
b = c + a;
}
Function invocation:
x = 1;
y = 2;
z = 3;
calc(x, y);
cout << x << " " << y << " " << z << endl;
- Since x is passed by value, its value remains 1.
- y is passed by reference to the function calc(x,y);
Tracing the function execution:
c=3
a=3
b=c+a = 6;
But b actually corresponds to y. So y=6 after function call.
- Since z is not involved in function call, its value remain 3.
So output: 1 6 3
C. ">" denotes the end of an element. For instance <b>Hello!</b> or <hr />
Answer:
The last character in the string processed is "t".
Explanation:
The index start from 0 and the len(fruit) is 5.
When index is 0 which is less than 5; "f" is printed
When index is 1 which is less than 5; "r" is printed
When index is 2 which is less than 5; "u" is printed
When index is 3 which is less than 5; "i" is printed
When index is 4 which is less than 5; "t" is printed
When index is 5, the condition is false; so the loop content is not executed.
Therefore, the last character traversed in the string "fruit" is "t".
