I need help with this question!

Arlecino [84]

Answer:

5 and 10

Explanation:

Given

The above code segment

Required

Determine the outputs

Analysing the code segment line by line

[This initialises c to 0]

c = 0

[The following iteration is repeated as long as c is less than 10]

while (c < 10):

[This increments c by 5]. Recall that c is initially 0. Hence, c becomes 0 + 5 = 5

c = c + 5

[This prints the value of c which is 5]

print(c)

The iteration is then repeated because the condition is still true i.e. 5 is less than 10

c = c + 5 = 5 + 5 = 10

[This prints the value of c which is 10]

print(c)

The iteration won't be repeated because the condition is now false i.e. 10 is not less than 10.

Hence, the output is 5 and 10.

The PATH environment variable.

enot [183]

Answer:

Answer explained below

Explanation:

Yes, you can let Set-uid program that is owned by root to run your code instead of /bin/ls but it has it's own drawbacks and is actually not safe.

As you can not rely on that since some of the shells if different from the ruid drop an euid which is actually not safe.

execl("/bin/ls", "ls",(char *)0);

run this under your main program.

Since it can have a root previlege,

-$ cd /tmp/

/tmp$ sudo su

:/tmp# gcc -o system system.c

:/tmp# chmod u+s system // changing file permissions

:/tmp# exit

exit

:/tmp$ cp /bin/sh /tmp/ls

:/tmp$ ./system

Steps:

1. The first thing you need to do is copy /bin/sh to /tmp.

2. After copying /bin/sh to /tmp set a new name ls but make sure your sh ->.zsh.

3. Set PATH to current directory. /tmp.

4. Compile

5. Run the program system and you can get your root previledge.

Now, with the above exmaple if you change /bin/sh soo that it points back to /bin/bash and repeat all the previous steps, you will not be able to get your root previledges.

Write a program that determines the value of the coins in a jar and prints the total in dollars and cents. Read integer values t

Shalnov [3]

Answer:

The programming language is not stated. To answer this question, I'll make use of python programming language.

The following units of conversions is used in this program

1 quarter = $0.25

1 dime = $0.10

1 nickel = $0.05

1 penny = $0.01

$1 = 100 cents

This program makes use of few comment (See explanation for line by line explanation)

Having listed the above, the program is as follows:

#prompt user for inputs

quarters = int(input("Number of Quarters: "))

dimes = int(input("Number of Dimes: "))

nickels = int(input("Number of Nickels: "))

pennies = int(input("Number of Pennies: "))

#Convert coins to dollars

dollar = 0.25 * quarters + 0.10 * dimes + 0.05 * nickels + 0.01 * pennies

print("Dollar Equivalent")

print(str(round(dollar,2))+" dollars")

cent = dollar * 100

print("Cent Equivalent")

print(str(round(cent,2))+" cents")

Explanation:

This first line is a comment

#prompt user for inputs

This line prompts user for value of quarters in the jar

quarters = int(input("Number of Quarters: "))

This line prompts user for value of dimes in the jar

dimes = int(input("Number of Dimes: "))

This line prompts user for value of nickels in the jar

nickels = int(input("Number of Nickels: "))

This line prompts user for value of pennies in the jar

pennies = int(input("Number of Pennies: "))

Using the coin conversion listed in the answer section, the user inputs is converted to dollars in the next line

dollar = 0.25 * quarters + 0.10 * dimes + 0.05 * nickels + 0.01 * pennies

The string "Dollar Equivalent" is printed using the next line

print("Dollar Equivalent")

This line prints the dollar equivalent of the converted coins

print(str(round(dollar,2))+" dollars")

Using the coin conversion listed in the answer section, the user inputs is converted to cents in the next line

cent = dollar * 100

The string "Cent Equivalent" is printed using the next line

print("Cent Equivalent")

This line prints the cent equivalent of the converted coins

print(str(round(cent,2))+" cents")

Please note that the dollar and cent equivalents are rounded to two decimal places. Even though, it's not a requirement of the program, it's a good programming practice
