Question

Write a program that prompts the user to enter five test scores and then prints the average test score. Indicate the average test score by printing it to the terminal.

Answer 1

Answer:

I am writing the program in C++ and Python.

C++ code:

#include <iostream>  // for input output functions

using namespace std;   // identifies objects like cin cout

int main() //start of main() function body

{  //  test scores variables are declared along with average and sum variables

 double test_score1, test_score2, test_score3, test_score4, test_score5, average, sum;      

   cout << "Enter 5 test scores: \n";  //prompts user to enter 5 test scores

   cin >> test_score1 >> test_score2 >> test_score3 >> test_score4 >> test_score5;  //reads values of five test scores entered by user

   sum = test_score1 + test_score2 + test_score3 + test_score4 + test_score5;  // calculates the sum of the five test scores

   average = sum / 5;      //computes the average of five test scores

   cout << "The average test score is: " << average;  

 //displays the computer average of the five test scores entered by the user

}

Explanation:

The program prompts the user to enter the values of 5 test scores. It the calculates the sum of all these 5 input test scores and stores the result in sum variable. In order to compute average test score the sum of these 5 test scores is divided by the total number of test scores that is 5 and the result is stored in average variable. Lastly it displays the average by displaying the value of the average stored in the average variable.

Python Program:

num=5  # total number of test scores

list=[]  #list to store values of 5 test scores

for i in range(0,num):  #loop to enter values of test scores

#prompts user to enter values for 5 test scores

   test_scores =int(input("Enter the five test scores"))

   list.append(test_scores)  #appends the input test scores in the list

average=sum(list)/num  #calculates sum of the values stored in list and #divides the value of sum with the total number of test scores i.e. 5

print("Average test score is: ",round(average,2))

#displays average of the five test scores rounding up to two decimal places

Explanation:

This is a small program in Python to compute average test score. If you want to take separate input for each of the five test scores you can use the following program:

#takes value for each test score seperately from user

testScore1 = int(input('Enter 1st test score: '))  

testScore2 = int(input('Enter 2nd test score : '))

testScore3 = int(input('Enter 3rd test score : '))

testScore4 = int(input('Enter 4th test score : '))

testScore5 = int(input('Enter 5th test score : '))  

#calculates sum of each test score

sum = (testScore1 + testScore2 + testScore3 + testScore4 + testScore5)  

#method to compute average test score

def average(sum):

   return sum / 5         #divide value of sum with total number of test scores  

#calls average function to display average test score using print statement

print("average test score is: " , average(sum))
