Question

Implement a version with the outer loop, with a while loop, and the inner loop with a do / while loop.

Modify this program as he ask ↑↑↑ C++

// This program averages test scores. It asks the user for the
2 // number of students and the number of test scores per student.
3 #include <iostream>
4 #include <iomanip>
5 using namespace std;

6
7 int main()
8 {
9 int numStudents, // Number of students
10 numTests; // Number of tests per student
11 double total, // Accumulator for total scores
12 average; // Average test score
13
14 // Set up numeric output formatting.
15 cout << fixed << showpoint << setprecision(1);
16
17 // Get the number of students.
18 cout << "This program averages test scores.\n";
19 cout << "For how many students do you have scores? ";
20 cin >> numStudents;
21
22 // Get the number of test scores per student.
23 cout << "How many test scores does each student have? ";
24 cin >> numTests;
25
26 // Determine each student's average score.
27 for (int student = 1; student <= numStudents; student++)
28 {
29 total = 0; // Initialize the accumulator.
30 for (int test = 1; test <= numTests; test++)
31 {
32 double score;
33 cout << "Enter score " << test << " for ";
34 cout << "student " << student << ": ";
35 cin >> score;
36 total += score;
37 }
38 average = total / numTests;
39 cout << "The average score for student " << student;
40 cout << " is " << average << ".\n\n";
41 }
42 return 0;
43 }

Ans

code:-

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

int numStudents,

numTests; // Number of tests per student

double total, //Accumulator for total scores

average; // Average test score

// Set up numeric output formatting.

cout << fixed << showpoint << setprecision(1);

// Get the number of students.

cout << "This program averages test scores.\n";

cout << "For how many students do you have scores? ";

cin >> numStudents;

// Get the number of test scores per student.

cout << "How many test scores does each student have? ";

cin>>numTests;

// Determine each student's average score.

int student=1;

while (student <= numStudents)

{

total = 0; // Initialize the accumulator.

int test=1;

do

{

double score;

cout << "Enter score " << test << " for ";

cout << "student " << student << ": ";

cin >> score;

total += score;

test++;

}

while(test<=numTests);

average = total / numTests;

cout << "The average score for student " << student;

cout << " is " << average << ".\n\n";

student++;

}

return 0;

}

If any doubt ask in the comments.
