In a linux script, the line ____ is important because it identifies the file as a script.

1 answer:

8 0

The closest line to that would be the first line:

#!/bin/bash

echo "Hello World!"

BTW, the "#!" is referred to as a she-bang. When those are the first characters executed, the (requires an absolute path) program that follows is launched, and the rest of this file is given to it as data. To run this like a program, the execute permissions need to be set ( chmod 0755 script.sh ).

Nikolay [14]

Answer:

100 or so atoms of the periodic table, in different combinations, make up Compounds.

Explanation:

Atoms from different element in the periodic table combined together with the help of bond and make a new product that is called compound.

For example

Hydrogen and oxygen are the elements of the periodic table. When one atom of oxygen and two atoms of hydrogen are combined together, a compound will be formed named as water (H20).

In another example, two atoms of oxygen and one atom of carbon combines toghther through chemical reaction and make compund named as Carbon dioxide (CO2).

viktelen [127]

Answer:

All of the above.

An operating system is a system software pre-installed on a computing device to manage or control software application, computer hardware and user processes.

This ultimately implies that, an operating system acts as an interface or intermediary between the computer end user and the hardware portion of the computer system (computer hardware) in the processing and execution of instructions.

Some examples of an operating system on computers are QNX, Linux, OpenVMS, MacOS, Microsoft windows, IBM, Solaris, VM etc.

Assume the following variable definition appears in a program:

AnnZ [28]

Answer:

cout << setprecision(2)<< fixed << number;

Explanation:

The above statement returns 12.35 as output

Though, the statement can be split to multiple statements; but the question requires the use of a cout statement.

The statement starts by setting precision to 2 using setprecision(2)

This is immediately followed by the fixed manipulator;

The essence of the fixed manipulator is to ensure that the number returns 2 digits after the decimal point;

Using only setprecision(2) in the cout statement will on return the 2 digits (12) before the decimal point.

The fixed manipulator is then followed by the variable to be printed.

See code snippet below

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

// Initializing the double value

double number = 12.3456;

//Print result

cout << setprecision(2)<< fixed << number;

return 0;

}
