Answer:
The buffer has room for 499 characters (you always have to reserve 1 for the terminating \0 character).
The code copies all characters passed in the commandline (argv[1]) into this buffer without checking. If there are more than 499 characters supplied, these will be copied into a memory location that is not intended for it. This will probably cause your program to crash, but if the extra data is somehow executed by the processor as if it were a program, this could be a way to sneak a virus into your computer.
So, while copying data, it is important to always limit the maximum amount to the allocated space.
Which wireless standard runs on both the 2.4 and 5 GHz frequencies?
Answer:
Approved in 2009, Wi-Fi 4 enables operation in both the 2.4 and 5 GHz frequencies, a game changer at the time.

Multiplying two numbers is a piece of cake, but how about multiplying three of them, either being a negative of positive number? With programming and proper code, these tasks are easy to handle.
You're a programmer, right? Then code this one for me!
Input
A line containing three numbers (positive or negative, may have decimal places) separated by a space.
1.6·-2·-1
Output
A line containing a decimal/float with one decimal place.
3.2
Answer:
from decimal import *
li = list(map(Decimal,input().split()))
result = li[0]*li[1]*li[2]
print(abs(result))
Explanation:
The proper or programming code to handle that multiplies three numbers is as follows:
from decimal import *
value = list(map(Decimal,input().split()))
result = value[0]*value[1]*value[2]
print(abs(result))
Code explanation:The code is written in python.
From the decimal module we have to import *. The decimal module incorporates a notion of significant places so that 1.3*1.2 = 1.56The variable value is used to store the list of the decimal inputThe variable result multiplies the three numbers in the list Finally we print the absolute value of the result.learn more on python here: https://brainly.com/question/19175881

What allows an individual to avoid capital outlay?
paying cloud by the month
paying cloud by the year
paying cloud by the hour
paying cloud by the day
The daily payment for cloud services would be most reasonable. Hence option A is correct.
Capital Outlay refers to the expenditure or payment for the acquisition cost of capital assets.
In this case, the assets whose cost of purchase is being avoided by expenditure on cloud services is IT Server Hardware and Software which can be outsourced to companies that provide Cloud as a Service.
Cloud Services is the provision of Cloud computing services on a pay-per-use basis.
One of the advantages of this service is that it mostly consists of self-service on-demand. Hence, no need for the physical asset which usually is very costly.

Explanation:
The option given above will assign a random integer in the range of 1 through 50 to the variable number is: "number = random.randint(1, 50)"
What is a random integer in programming?This is a random sequence of integers that may be used to imitate things like shuffling a deck of cards or creating distinct behaviors every time a program runs. The RND function in BASIC generates random numbers. This yields a value between 0 and 1.
Random number creation is a technique that generates a series of numbers or symbols that cannot be realistically anticipated better than by random chance, generally using a random number generator (RNG).

Program Rock.java contains a skeleton for the game Rock, Paper, Scissors. Add statements to the program as indicated by the comments so that the program asks the user to enter a play, generates a random play for the computer, compares them and announces the winner (and why). For example, one run of your program might look like this:
Enter your play: R, P, or S
r
Computer play is S
Rock crushes scissors, you win!
Note that the user should be able to enter either upper or lower case r, p, and s. Add a loop to make sure the user only enters an R, P, or S. The user's play is stored as a string to make it easy to convert whatever is entered to upper case. Use if statements to convert the randomly generated integer for the computer's play to a string.
public class Rock
{
public static void main(String[] args)
{
String personPlay; //User's play -- "R", "P", or "S"
String computerPlay; //Computer's play -- "R", "P", or "S"
int computerInt; //Randomly generated number used to determine
//computer's play
// Add the code for each action beneath the comment. // more than one line may be needed in some cases // Get player's play -- note that this is stored as a string
// Make player's play uppercase for ease of comparison
// Generate computer's play (0,1,2) – use (int) (Math.random() * 3) to
// generate a random play
// Translate computer's randomly generated play to string // using mutually exclusive conditional statements
// Print computer's play
// See who won. Use nested ifs instead of &&.
}
}
People hardly ever play Rock, Paper, Scissors one game at a time. They play matches that are best 2 out of 3, best 3 out of 5, etc. Change your program to prompt the user for the odd number of games they want to play and use a loop to make sure it is an odd number. Then, add a loop to your program to play the game multiple times. Keep track of who wins, and make sure the loop stops when either the computer or the user has accumulated enough wins. Ties do not count in either the game total or the win totals – so a best 2 out of 3 match requires 3 games to be played where someone wins 2 times.
