Question

C++

Write a program to input eight integer numbers into an array named grade. As each number is input, add the number into a total. After all numbers are input, display the numbers and their average. (You can use cin to take number or use rand() to assign random numbers to the array.)

C++

Answer 1

#include <iostream>

#include <iomanip>

using namespace std;

int main()

{

int sum = 0;

int grade[8];

int inp;

cout << "\nYou must enter 8 scores and the program will display all your scores along with the average score.\n";

for(int i = 0; i < 8; i++)

{

cout << "Enter score " << (i + 1) << ": ";

cin >> inp;

while(inp <= 0 || inp > 100)

{

cout << "Score must be between 1 and 100!\n\n";

cout << "Enter score " << (i + 1) << ": ";

cin >> inp;

}

grade[i] = inp;

sum += inp;

}

double average = ((double)sum) / 8.00;

cout << "\nYOUR SCORES AND AVERAGE:\n------------------------\n";

for(int i = 0; i < 8; i++)

{

cout << "Score " << (i + 1) << ": " << grade[i] << endl;

}

cout << setprecision(2) << fixed << "Average = " << average << endl;

return 0;

}
