Design a GUI program to find the weighted average of four test scores. The four test scores and their respective weights are giv

en in the following format: testscore1 weight1 ... For example, the sample data is as follows: 75 0.20 95 0.35 85 0.15 65 0.30 The user is supposed to enter the data and press a Calculate button. The program must display the weighted average.

<u>Answer:</u>

I am writing <em>partial code in</em> <em>c++ to calculate weighted average</em>. The weighted average should be calculated based on multiplying the test score and its <em>respective weight and finally add all the test score.</em>

<u>Explanation:</u>

<em>int arrtestscore[100];</em>

<em>int arrweight[100];</em>

<em>int n;</em>

<em>double weightedavg;</em>

<em>cout<<”Enter the number of test score for which weighted average needs to be calculated”;</em>

<em>cin>>n;</em>

<em>for(int x = 0; x <n;x++)</em>

<em>{</em>

<em> cout<<”Enter test score :” + (x+1) ;</em>

<em> cin>>arrtestscore[x];</em>

<em> count<<”Enter the respective weight:”;</em>

<em> cin>>arrweight[x];</em>

<em>}</em>

<em>for (int i=0; i<n;i++)</em>

<em>{</em>

<em> weightedavg = weightedavg + (arrtestscore[i] * arrweight[i])</em>

<em>}</em>

<em>cout<<”weighted average = “ <<weightedavg; </em>

Write a script that calculates the common factors between 8 and 24. To find a common factor, you can use the modulo operator (%)
AnnyKZ [126]

Answer:

  1. common = []
  2. num1 = 8
  3. num2 = 24
  4. for i in range(1, num1 + 1):
  5.    if(num1 % i == 0 and num2 % i == 0):
  6.        common.append(i)
  7. print(common)

Explanation:

The solution is written in Python 3.

Firstly create a common list to hold a list of the common factor between 8 and 24 (Line 1).

Create two variables num1, and num2 and set 8 and 24 as their values, respectively (Line 3 - 4).

Create a for loop to traverse through the number from 1 to 8 and use modulus operator to check if num1 and num2 are divisible by current i value. If so the remainder of both num1%i and num2%i  will be zero and the if block will run to append the current i value to common list (Line 6-8).

After the loop, print the common list and we shall get [1, 2, 4, 8]

ProcessName2
RoseWind [281]

Explanation:

This is easily solvable with a for loop. Something like:

(I assume c++)

#include <iostream>

#include <string>

int main() {

take_input: //tag

std::string input;

cin >> input; //take the input

int spaceCount = 0;

char checking;

for(unsigned int i = 0; i == input.length(); ++i) {

checking = spaceCount[i];

if(checking == ' ')

spaceCount++;

}

if(spaceCount >= 1 && input.length >= 5)

std::cout << "Your name is " + input;

else

goto take_input; // reasks for input if the conditions are not met

return 0;

};

**remove all spaces before using the code, the if statements are messed up
