Answer:
1. Option A: for loop is correct
2. Option B: while loop is correct
Explanation:
Two loops are used commonly. For and while
For is used when the number of iterations are already known and while is used when number of iterations is not known and the loop has to be terminated based on any condition.
<u>1. You are finding the batting average of 13 baseball players.
</u>
For loop will be used as the number of iterations is already known. The score of 13 players has to be used to calculate the average so there will be 13 iterations. Hence, for loop will be used.
<u>2. You are asking your users for the names of all the stores where they shopped to find their friend's birthday present. They will show they are done by entering the word "done."</u>
While loop will be used as the termination of loop depends on the input given by the user so the number of iterations are not already known.
Hence,
1. Option A: for loop is correct
2. Option B: while loop is correct
AutoSum is a feature in Microsoft Excel which involves you as the user being able to input some sort of formula and for it to apply to all selected cells. It works in many different ways. For example, it has the ability to auto fill so that it fills the cells with numbers from 1-100. Or days of the week, or months of the year. If you were creating a Gantt chart for project management, you would want to auto fill the consecutive days of which you want the project to run for.
Answer:
The algorithm:
Input days
sum = 0
for i = 1 to 
input text
sum = sum + text
end for
average = sum/days
print average
The program in pascal:
var days, sum, text, i:integer;
var average : real;
Begin
write ('Days: '); readln(days);
sum:=0;
for i := 1 to do 
write ('Text: '); readln(text);
sum:=sum+text;
end;
average := (sum/days);
writeln ('The average text is' , average);
End.
Explanation:
This declares all variables
var days, sum, text, i:integer;
var average : real;
This begins the program
Begin
This gets the number of days from the user
write ('Days: '); readln(days);
Initialize sum to 0
sum:=0;
This iterates through the days
for i := 1 to do begin
This gets the text for each day
write ('Text: '); readln(text);
This sums up the texts
sum:=sum+text;
End loop
end;
Calculate average
average := (sum/days);
Print average
writeln ('The average text is' , average);
End program
End.
