Which directory in the FHS stores programs and configuration information that can only be executed and modified by the root user

dlinn [17]

Answer: /sbin

Explanation:

In Linux, FHS describes the directory content and the way in which Operating System files are displayed to the user.

/sbin is a directory that contains executable programs. s/bin is the short form of system binaries. System binaries require root rights to perform specific tasks. /sbin contains binaries that are crucial to boot the system and also to recover and restore the system. /bin directory also contains the commands to boot the system but the main difference between both is that /sbin programs can only be executed by the root user. Examples are fdisk, fsck, root,halt, init, grub, ifconfig.

mafiozo [28]

Answer:

Following are the code to this question:

#include<iostream>//import header file

using namespace std;

int main()//defining main method

{

int ar[7];//defining 1_D array that stores value

int i,x=0,l1=1,j; //defining integer variable

for(i=0;i<7;i++)//defining for loop for input value from user ends

{

cout<<"Enter a Number: ";//print message

cin>>ar[i];//input value in array

if(l1<=2 && i>0)//using if block that checks the array values

{

x++;//increment the value of x by 1

}

if(l1>2 && i>0)//using if block that checks the array values

{

l1=l1-2;//using l1 variable that decrases the l1 value by 2

}

j=i-x;//using j variable that holds the index of the root of the subtree

if(i>0 && ar[j]>ar[i])// use if block that checks heap condition

{

l1++; //increment the value of l1 variable

}

if(i>0 && ar[j]<ar[i])// using the if block that violate the heap rule

{

cout<<ar[i]<<" "<<"Violate the heap";//print message with value

break;//using break keyword

}

return 0;

}

Output:

1)

Enter a Number: -15

Enter a Number: -5

-5 Violate the heap

2)

Enter a Number: 45

Enter a Number: 0

Enter a Number: 55

55 Violate the heap

Explanation:

In the above-given C++ language code, an array "ar" and other integer variables " i,x,l1, j" is declared, in which "i" variable used in the loop for input values from the user end.
In this loop two, if block is defined, that checks the array values and in the first, if the block it will increment the value of x, and in the second if the block, it will decrease the l1 value by 2.
In the next step, j variable is used that is the index of the root of the subtree. In the next step, another if block is used, that checks heap condition, that increment the value of l1 variable. In the, if block it violate the heap rule and print its values.
