Answer: Include double quote character in a string.

Explanation:

Escape sequence characters are not represented by itself, when it is use in the string,literals and character. It is difficult to represent them directly in sequence of characters.

Some characters does not get included directly in the string constant so, that is why we need escape sequence to include double quotes value in string.

Example of double quote are:

Sample\"sample

Then the output is:

sample"sample

Answer:

Program is in C++

Explanation:

C++ Code:

#include <iostream>

#include <cctype>

using namespace std;

int main(){

char ch;

do{

cout<<"Enter Character: ";

cin>>ch;

if (isupper(ch)){

cout<<"OK"<<"\n";

}

while(ch!='!');

return 0;

}

_______________________________________

Code Explanation

First execute a do while loop as we want user to enter at least first character to check whether its upper case or not. If user enters exclamation character then this loop will terminate along with the program.

To check whether the entered character is upper case or not we will be using isupper(ch) method defined in cctype library.

If the character is upper case then if condition will show Ok by printing it using cout and this program will show nothing if the character is not upper case.

Sample Output

Enter Character: A

Enter Character: b

Enter Character: c

Enter Character: d

Enter Character: E

Enter Character: G

Enter Character: F

Enter Character: !

(4 points.) Write an algorithm (i.e., step-by-step instructions) via which someone could walk or drive from some origin to some

Elis [28]

Answer:

The algorithm is as follows :

1. Record Current Position, Final Destination

2. While Current Position is not Final Destination, repeat the following:

2.1 If destination location is up then:

2.1.1 If an obstacle is directly above you then:

2.1.1.1 Look for alternate position (left, right, down)

2.1.1.2 If alternate position is found then

2.1.1.2.1 Move there

2.1.1.2.2 Record Current Position

2.1.1.3 If no alternate position is found then

2.1.1.3.1 Call for help

2.1.1.3.2 End

2.1.2 If no obstacle is directly above you then:

2.1.2.1 Move up

2.1.2.1 Record Current Position

2.2 If destination location is down then:

2.2.1 If an obstacle is directly below you then:

2.2.1.1 Look for alternate position (left, right, up)

2.2.1.2 If alternate position is found then

2.1.1.2.1 Move there

2.2.1.2.2 Record Current Position

2.2.1.3 If no alternate position is found then

2.2.1.3.1 Call for help

2.2.1.3.2 End

2.2.2 If no obstacle is directly below you then:

2.2.2.1 Move down

2.1.2.1 Record Current Position

2.3 If destination location is right then:

2.3.1 If an obstacle is directly by your right then:

2.3.1.1 Look for alternate position (down, up, left)

2.3.1.2 If alternate position is found then

2.3.1.2.1 Move there

2.3.1.2.2 Record Current Position

2.3.1.3 If no alternate position is found then

2.3.1.3.1 Call for help

2.3.1.3.2 End

2.3.2 If no obstacle is directly by your right then:

2.3.2.1 Move right

2.3.2.1 Record Current Position

2.4 If destination location is left then:

2.4.1 If an obstacle is directly by your left then:

2.4.1.1 Look for alternate position (down, up, right)

2.4.1.2 If alternate position is found then

2.4.1.2.1 Move there

2.4.1.2.2 Record Current Position

2.4.1.3 If no alternate position is found then

2.4.1.3.1 Call for help

2.4.1.3.2 End

2.4.2 If no obstacle is directly by your left then:

2.4.2.1 Move left

2.4.2.1 Record Current Position

Explanation:

The algorithm is straight forward.

All it does is to check for available position and move into the position if there is any available.

It keeps checking and moving until an obstacle prevents it from moving.

A network administrator is configuring an ACL with the command access-list 10 permit 172.16.32.0 0.0.15.255. Which IPv4 address

lord [1]

Answer:

For this wild card mask 0.0.15.255 the ACE IP address will be 172.16.47.254

Explanation:

ACL is the access control list that is used to enlist the ip addresses that allowed or restricted to access the network. ACE is an IP address from the list ACL that has all rules and regulations related to access of network. The ACE could be in the range of IP address in ACL. ACL can be calculated with the help of initial IP address adding with wild card mask.

Initial IP address is = 172.16.32.0

Wild card mask =0.0.15.255

by adding above values we can find the last IP address of ACL.

after addition

Final IP address is = 172.16.47.255

The options that are available with question, Only option between the range is 172.16.47.254. So we can say that This is the only ACE IP address in options.
