90 and above
cout

cout << "B";
else if ( grade >= 70 ) // 70-79
cout << "C";
else if ( grade >= 60 ) // 60-69
cout << "D";
else // less than 60
cout << "F";

что функция True/False
Пример:
While (Условия){
Выполнения каких либо действий пока не

достигнет True/False
}

Работа с While

grade;
int average;

total = 0;
gradeCounter = 1;

while(gradeCounter grade;
total

= total + grade;
gradeCounter = gradeCounter + 1;
}
average = total/10;
cout<<"Среднее значение" <return 0;
