Console.WriteLine("What grade are you in?");
int grade = Convert.ToInt32(Console.ReadLine());
if (grade == 9)
{
Console.WriteLine("Freshman");
}
if (grade == 10)
{
Console.WriteLine("Sophomore");
}
if (grade == 11)
{
Console.WriteLine("Junior");
}
if (grade == 12)
{
Console.WriteLine("Senior");
}
if (grade < 8)
{
Console.WriteLine("Not in High School");
}
Explanation:
The first line asks what grade are you in, then when the user types in the grade it saves it in a variable. We then use that variable for the conditionals. The conditional states, whatever grade level your in, it prints your high school year title. If anything is lower than 8, it will print not in high school.
