I need to enter 10 students names I did a loop but it does not work well
# include <iostream>
# include <string>
using namespace std;
//functions prototype
void avg (double& average);
char grade(double& average);
int main()
{
// String variable for the student's name
string name;
double theAverage = 0;
// Prompts the name of the student
cout << "Student name: ";
//Reads from keyboard
getline(cin, name);
// sends theAverage into the avg()
avg(theAverage);
cout << "The average grade for "
<< name << " is "
<< theAverage << "."<<endl;
cout << "And his/her grade is " << grade(theAverage) <<endl;
return 0;
}
//the average calculating function
void avg (double& average)
{
int grade[5];
double sum = 0;
cout << endl;
// The loop to get the grades and sum them
for (int i=0; i<5; i++)
{
cout << "Please enter grade: ";
cin >> grade[i];
sum += grade[i];
}
cout << endl;
// Caclulates the average after the loop ends
average = sum / 5;
}
char grade(double& average)
{
if (average >=90 && average <=100)
return 'A';
if (average >=80 && average <90)
return 'B';
if (average >=70 && average <80)
return 'C';
if (average >=60 && average <70)
return 'D';
else
{
return 'F';
}
}
