Declare a seven-row, two-column int array named temperatures. The program should prompt the user to enter the highest and lowest temperatures for seven days. Store the highest temp in the first column and the lowest in the second column. The program should display the average high and average low temperature. Display the average temperatures with one decimal place.
Answers
Answer:
Following are the code to the given question:
#include<iostream>//header file
#include<iomanip>//header file
using namespace std;
int main()//main method
{
double temperatures[7][2];//defining a double array temperatures
double lowAvg=0, highAvg=0;//defining a double variable
for(int i = 0;i<7;i++)//defining loop to input the value
{
cout<<"Enter day "<<(i+1)<<" highest temperatures: ";//print message
cin>>temperatures[i][0];//input highest temperatures value
cout<<"Enter day "<<(i+1)<<" lowest temperatures: ";//print message
cin>>temperatures[i][1];//input lowest temperatures value
}
cout << fixed << setprecision(1);//using the setprecision method
for(int i = 0;i<7;i++)//defining loop to calculating the Average of the
{
highAvg += temperatures[i][0];//holding highest value
lowAvg += temperatures[i][1];//holding lowAvg value
}
cout<<"Average high temperature = "<<highAvg/7<<endl;//calculate amd print highest temperature Average
cout<<"Average low temperature = "<<lowAvg/7<<endl;//calculate amd print lowest temperature Average
return 0;
}
Output:
Please find the attached file.
Explanation:
In this code, a 2D array "temperatures" and two-variable "highAvg, lowAvg" as double is declared, that uses the two for loops.In the first loop, it uses an array to input the value from the user-end.In the second loop, it uses the double variable that calculates the average value of the temperature.

Given the declaration: char a[] = "Hello"; char *p = a, *q; what operations are valid syntactically? Select all that apply. Group of answer choices q = &&a[0]; q = &&a; *q = *(&a[0]); q = &(*p);
Answers
Answer:
The valid operations are:
*q = *(&a[0]); and q = &(*p);
Explanation:
Given
The above declarations
Required
The valid operations
*q = *(&a[0]); and q = &(*p); are valid assignment operations.
However, q = &&a[0]; q = &&a; are invalid because:
The assignment operations intend to implicitly cast the char array a to pointer q. C++ does not allow such operation.
Hence, *q = *(&a[0]); and q = &(*p); are valid
Another way to know the valid operations is to run the program and look out for the syntax errors thrown by the C++ compiler
why absolute reference is used in spreadsheet
Answers
Absolute reference is used especially to keep the value or content of a column or row constant.
Explanation:Cell referencing is one common and important concept in spreadsheets. A cell reference or cell address is a value, mostly alphanumeric, used to identify a specific cell or cell range in a worksheet.
In spreadsheets such as that of Microsoft - excel - there are basically two types of referencing.
i. relative referencing
ii. absolute referencing
iii. mixed referencing
Relative reference is the default cell reference. When a relative reference is copied and pasted across multiple cells, it changes depending on its relative position. This type of reference is especially useful when there is a need to apply same formula across multiple rows or columns.
Absolute reference, on the other hand, will not change even though it is copied across multiple cells. It is used especially to keep the value or content of a column or row constant.
Mixed reference is a hybrid of the relative and absolute references.

A buffer is filled over a single input channel and emptied by a single channel with a capacity of 64 kbps. Measurements are taken in the steady state for this system with the following results:
Average packet waiting time in the buffer = 0.05 seconds
Average number of packets in residence = 1 packet
Average packet length = 1000 bits
The distributions of the arrival and service processes are unknown and cannot be assumed to be exponential.
Required:
What are the average arrival rate λ in units of packets/second and the average number of packets w waiting to be serviced in the buffer?
Answers
Answer:
a) 15.24 kbps
b) 762 bits
Explanation:
Using little law
a) Determine the average arrival rate ( λ ) in units of packets/s
λ = r / Tr --- 1
where ; r = 1000 bits , Tr = Tw + Ts = 0.05 + (( 1000 / (64 * 1000 )) = 0.0656
back to equation 1
λ = 1000 / 0.0656 = 15243.9 = 15.24 kbps
b) Determine average number of packets w to be served
w = λ * Tw = 15243.9 * 0.05 = 762.195 ≈ 762 bits

a.
amount = balance + amount;

b.
balance = amount;

The code that does this task is (e).
Assume the following:
[tex]balance = 5000; amount = 2000;[/tex]
So, code (e) is as follows:
balance = balance + amount; [tex]\to[/tex]
[tex]balance = 5000 + 2000[/tex] [tex]\to[/tex]
[tex]balance = 7000[/tex]
Here, the updated value of balance is 7000
So: return balance
will return 7000 as the updated account balance
Other options are incorrect

The main difference between a monitor and a television is that a monitor does not have a television tuner to change channels. Monitors often have higher display resolution than televisions.
A printer is a device that accepts text and graphic output from a computer and transfers the information to paper, usually to standard size sheets of paper. Printers vary in size, speed, sophistication, and cost. In general, more expensive printers are used for higher-resolution color printing.
Speakers receive audio input from the computer's sound card and produce audio output in the form of sound waves. Most computer speakers are active speakers, meaning they have an internal amplifier which allows you to increase the volume, or amplitude, of the sound.

Example 1:
Enter a value: 11222
Output: Input number is valid
Example 2:
Enter a value: 1234
Output: Input number is invalid

cout << number << (valid ? " is valid" : " is invalid");
}
Explanation:
Regular expressions can do all of your checking except for the sum of digits check. The checks are i.m.o. easiest if you don't treat the input as a number, but as a string with digits in it.
The regex means:
^ start of string
\d{4} exactly 4 digits
[02468] one of 0, 2, 4, 6 or 8 (this is what makes it even)
$ end of string

Answer:
Following are the response to the given question:
Explanation:
The glamorous objective is to examine the items (as being the most valuable and "cheapest" items are chosen) while no item is selectable - in other words, the loading can be reached.
Assume that such a strategy also isn't optimum, this is that there is the set of items not including one of the selfish strategy items (say, i-th item), but instead a heavy, less valuable item j, with j > i and is optimal.
As [tex]W_i < w_j[/tex], the i-th item may be substituted by the j-th item, as well as the overall load is still sustainable. Moreover, because [tex]v_i>v_j[/tex] and this strategy is better, our total profit has dropped. Contradiction.
