Write a python program to read four numbers (representing the four octets of an IP) and print the next five IP addresses. Be sur

sdas [7]

Answer:

first_octet = int(input("Enter the first octet: "))

second_octet = int(input("Enter the second octet: "))

third_octet = int(input("Enter the third octet: "))

forth_octet = int(input("Enter the forth octet: "))

octet_start = forth_octet + 1

octet_end = forth_octet + 6

if (1 <= first_octet <= 255) and (0 <= second_octet <= 255) and (0 <= third_octet <= 255) and (0 <= forth_octet <= 255):

for ip in range(octet_start, octet_end):

forth_octet = forth_octet + 1

if forth_octet > 255:

forth_octet = (forth_octet % 255) - 1

third_octet = third_octet + 1

if third_octet > 255:

third_octet = (third_octet % 255) - 1

second_octet = second_octet + 1

if second_octet > 255:

second_octet = (second_octet % 255) - 1

first_octet = first_octet + 1

if first_octet > 255:

print("No more available IP!")

break

print(str(first_octet) + "." + str(second_octet) + "." + str(third_octet) + "." + str(forth_octet))

else:

print("Invalid input!")

Explanation:

- Ask the user for the octets

- Initialize the start and end points of the loop, since we will be printing next 5 IP range is set accordingly

- Check if the octets meet the restrictions

- Inside the loop, increase the forth octet by 1 on each iteration

- Check if octets reach the limit - 255, if they are greater than 255, calculate the mod and subtract 1. Then increase the previous octet by 1.

For example, if the input is: 1. 1. 20. 255, next ones will be:

1. 1. 21. 0

1. 1. 21. 1

1. 1. 21. 2

1. 1. 21. 3

1. 1. 21. 4

There is an exception for the first octet, if it reaches 255 and others also reach 255, this means there are no IP available.

- Print the result

What is the symbol that causes the computer to perform string concatenation?

neonofarm [45]

Answer: In java the symbol "+" operator is used to perform string concatenation.

Explanation:

String concatenation refers to joining of two strings. So in java + is used to join strings which works provided one of the operands must be a String variable. Then it works by converting the other variable to String variable and joins the second operand to the end of the first operand.

An example of String concatenation is as follows:

int age = 10;

System.out.println("The boys age is " + age);

Output:

The boys age is 10.

here, the age is integer variable but as the phrase "The boys age is" is a String variable so it converts the age to String variable and joins both the Strings.

Suppose cell C5 contains the formula =B$6+C1. Match each formula with its respective cell if you copied it.

amm1812

Answer:

The options are not being given. However, we can place the $ sign in front of letter or number we make it constant across the rows or across the columns. By $B we mean, the column will remain same as B as we move across the rows down or up, and by $6 we mean the row will remain fixed to 6 as you move right or left of the cell where you place $6.

Thus, B$6 + C1,will change to below as you move down:

B$6 + C2

B$6 + C3

B$6 + C5

...... and so on.

and if we move left, it will become:

C$6 +D6

D$6 +E6

E$6 +F6

.........and so on.

Please keep an eye on the letter and number, the way they change in each condition, like if its B the next is C irrespective of columns where the next column starts.

Explanation:

The answer is self explanatory.
