Answer 1

Following are the program of C++

#include <iostream> // header file

#include <iomanip> // header file

using namespace std; // namespace

int main() // main function

{

int grade[5],k; // declaration of array and variable

for (int i = 0; i< 5; i++) // iterating over the loop

{

cout << "Enter grade ";

cin >> grade[i]; // read the grade by the user

}

k=0;

while(k<5) // iterating over the loop

{

cout << "Grade #" << k + 1 << ": ";

cout << grade[k] << endl; // display the grade

k++; // increment of i

}

}

Output:

Enter grade 45

Enter grade 5

Enter grade 8

Enter grade 6

Enter grade 7

Grade #1: 45

Grade #2: 5

Grade #3: 8

Grade #4: 6

Grade #5: 7

Answer 2

Following are the program of C++

#include <iostream> // header file

#include <iomanip> // header file

using namespace std; // namespace

int main() // main function

{

int grade[5],k; // declaration of array and variable

for (int i = 0; i< 5; i++) // iterating over the loop

{

cout << "Enter grade ";

cin >> grade[i]; // read the grade by the user

}

k=0;

while(k<5) // iterating over the loop

{

cout << "Grade #" << k + 1 << ": ";

cout << grade[k] << endl; // display the grade

k++; // increment of i

}

}

Output:

Enter grade 45

Enter grade 5

Enter grade 8

Enter grade 6

Enter grade 7

Grade #1: 45

Grade #2: 5

Grade #3: 8

Grade #4: 6

Grade #5: 7

Explanation:

The description of the program is given below.

• Declared an array "grade" of int type
• Read the grade elements by the user using the for loop
• finally, display the grade in the given format which is mention in the question.
