Every counting number's square is added to the total total by multiplying it by (k*k); this causes the value of k to increase and the next counting number to be reached.
Compute the programm?The c++ program for the given scenario is as follows.
#include
using namespace std;
int main() {
int k, total;
k=1;
total=0;
while(k<=50)
{
Every counting number's square is added to the total total by multiplying it by (k*k); this causes the value of k to increase and the next counting number to be reached.
k++; cout "Sum of squares of first 50 counting numbers is "; total "Sum of squares of first 50 counting numbers is 42925"
Explanation:
K and total are the only variables used in the program, as already explained. Integer data types are specified for these variables.
Initial values for variable total are 0, and for variable k are 1.
k=1;
total=0;
Variable k is used to represent counting number whose square is added to the variable total. Hence, values are taken accordingly.
The while loop is also known as the pre-test loop. This loop first evaluates the given condition and executes if the condition is satisfied.
while(k<=50)
The above while loop will execute till the value of variable k is less than or equal to 50. Once the value of k exceeds 50, the loop gets terminated. The loop executes 50 times, beginning from the value of 1 till k reaches 50.
The value of k is squared and added to the variable total each time the loop executes.
total = total + (k*k);
After the square is added to total, value of variable k is incremented by 1. This new value represents the next counting number.
k++;
After 50 executions of the loop, total variable will hold the sum of the squares of all the numbers from 1 to 50. The sum is displayed at the end.
This program implements the simplest logic for calculation of sum using two variables. The other loops such as for loop and do-while loop only differ in the placement and/or evaluation of the test condition.

The following function call inF - 'catInTheHat.txt outF - 'catRepWords.txt' repeat Words(inF, outF) should create the file catRep Words.txt with the content: too to sit Hint: Be sure to test your solution with input in which some repeated words on a line are a mixture of upper and lower case, and in which repeated words sometimes are preceded or followed by punctuation
To write the code for this exercise, we must be familiar with Python's computational language.
The image that is attached contains this code.
The code is explained as follows to make it clearer:
Define repeat words with first and second files:
infile 1=open
(firstFile,'r')
content1=infile 1.read()
infile 1.close()
import text
newContent=""
char in content1 for:
newContent+=char.strip(string.punctuation)
newContent=newContent.lower()
newContent=newContent.split()
repeated list=[]
in newContent for word:
If word.count(newContent)>1, then
repeated list.append(word)
new repeat list=[]
for the repeated list item:
item not included in the new repeat list:
new repeat list.append(item)
outfile=open(secondFile,'w')
in new repeat list for repeat:
outfile.write(repeat)
outfile.write('\n')
outfile.close()
infile 2=open(secondFile,'r')
content2=secondFile.read()
infile 2.close()
deliver content2
in file equals "aa.txt"
output file: "cpu.txt"
repeat words(in file, out file) in print.

5. 26 a servomechanism position control has the plant transfer function you are to design a series compensation transfer function in the unity feedback configuration to meet the following closed- loop specifications: the response to a reference step input is to have no more than overshoot. The response to a reference step input is to have a rise time of no more than sec. The steady-state error to a unit ramp at the reference input must be less than. A. Design a lead compensation that will cause the system to meet the dynamic response specifications, ignoring the error requirement. B. What is the velocity constant for your design? does it meet the error specification? c. Design a lag compensation to be used in series with the lead you have designed to cause the system to meet the steady-state error specification. D. Give the matlab plot of the root locus of your final design. E. Give the matlab response of your final design to a reference step
Proportional controllers respond to the magnitude of the error by providing an output to the actuator that is a multiple of (proportional to) the error. The gain is the multiple (gain = output / input).
The output is 50% when the error is 0 (the measurement is equal to the setpoint). Examples with different proportional band values. The required change requires a significant error when the proportional band is set too high. A small error can result in a large change in the output that overcompensates when the proportional band is set too low. This can cause the system to oscillate out of control, much like feedback from a public address system.

Assume the availability of an existing class, ICalculator, that models an integer arithmetic calculator and contains: an instance variable currentValue that stores the current int value of the calculator and can be accessed and modified by any subclass. methods add, sub, mul, and div Each method in ICalculator receives an int argument and applies its operation to currentValue and returns the new value of currentValue. So, if currentValue has the value 8 and sub(6) is invoked then currentValue ends up with the value 2, and 2 is returned. So, you are to write the definition of a subclass, ICalculator2, based on ICalculator. The class ICalculator2 has one additional method, negate, that receives no arguments. The effect of negate is to reverse the sign of currentValue. For example, if currentValue is zero, there is no change, if it is -22 then it becomes 22, if it is 100 it becomes -100. Furthermore negate returns the new value of currentValue.

FILL IN THE BLANK. what a nested function in cell g8 that displays the word flag if the payment type is credit and the amount is greater than or equal to $4000. otherwise, the function will display a ___ cell.
A Formulas cell will be displayed by the function.
Explain about the Formulas cell?Using a formula, you can compute values in a single cell or over a number of cells. The values in cells A2 through A4 can be added together using a formula like =A2+A2+A3+A4 for instance. Excel already has a function that is a predefined formula.
The cell where you want to enter the formula must be clicked on the worksheet. The constants and operators you want to employ in the computation should be typed after the equal sign (=), up to a maximum of 8192 characters.
The toolbar that allows you to enter or see data in a cell is called the formula bar, and it is located at the top of the spreadsheet. Click on a cell to view the contents of it by looking at the formula bar after using the formula bar to view information.
