A teacher has five students who have taken four tests. The teacher uses the following grading scale to assign a letter grade to
AlladinOne [14]

Answer:

#include <iostream>

using namespace std;

int main()

{

const int numofStudents = 5;//number of students

const int numofTests = 2;//number of tests taken by students

const int grade = 5;//number of grades available

char letter[grade] = { 'A','B','C','D','F' };

double table[numofStudents][numofTests];//defining 2darray with names and scores

string names[numofStudents];//storing names of students

for (int num = 0; num < numofStudents; num++)//storing names and scores of students

{

 cout << "Enter student's name: ";

 cin >> names[num];

 for (int test = 0; test < numofTests; test++)//scores loop

 {

  cout << "Enter the test score: ";

  cin >> table[num][test];

  if (table[num][test] < 0 || table[num][test]>100)//input validation

  {

   cout << "Invalid input. Try again" << endl;

   cin >> table[num][test];//input again

  }

 }

}

for (int i = 0;i < numofStudents;i++)//calculating averages and grades

{

 int sum = 0;

 cout << "Test scores for " << names[i] << ": " << endl;

 for (int j = 0;j < numofTests;j++)

 {

  cout << table[i][j] << " ";

  sum += table[i][j];//summing scores

 }

 cout << endl;

 float average = (float)sum / numofTests;//calculating the average

 cout << "Making an average of: "<< average;

 if (average <= 100 && average >= 90)//assigning a grade

 {

  cout << " and has received an " << letter[0];

 }

 else if (average <= 89 && average >= 80)

 {

  cout << " and has received a " << letter[1];

 }

 else if (average <= 79 && average >= 70)

 {

  cout << " and has received a " << letter[2];

 }

 else if (average <= 69 && average >= 60)

 {

  cout << " and has received a " << letter[3];

 }

 else if (average <= 59 && average >= 0)

 {

  cout << " and has received an " << letter[4];

 }

 else

 {

  cout << "Invalid scores entered." << endl;

 }

 cout << endl;

}

 return 0;

}

Explanation:

We first define the number of students, number of tests and number of grades available for assignments. We then fill in the 2D array of students names and their scores making sure assigning more than 100 and less than 0 is not allowed. We then sum the scores and retrieve an average. Using the average, a letter grade is assigned to that individual.

Answer:

Translate ➡️ allows the user to change words from one language to another

Smart Lookup➡️allows user to find the definition of a word or a phrase.

Thesaurus ➡️ allows the user to find the synonyms and antonyms of a word.

Explanation:

I have been able to match each took to the tasks that they perform.

In Translate, users can easily change words into a different language. That means that words in English can be translated into French, Spanish, etc., and vice versa.

In Smart Lookup, users can actually find definitions of words or phrases. Smart Lookup can be found in Microsoft Word Office.

The Thesaurus is used to find the synonyms and antonyms of words.

These tools make learning very easy and enjoyable.
