2.02 IN...a little bit long-winded, I did this inside the foreach loop to output the same result

foreach(int grade in grades)
{
int x = grade;
x*=2;
Console.WriteLine($"Grades = {x}");
}

[nathanielhansel]

so the 'grade' is just a placeholder variable for each record in the list? Like I could name it anything I wanted? And is this considered a variable or something else?

[MrFarkasOfficial]

Can a for each loop return the element? Foreach (string item in list) {If(some condition) { return item}} for example.

[MrFarkasOfficial]

Well done, I found this super useful. Subbed, naturally.

[mohmedfakhry]

so basically foreach for reading not modyfing elements

What is the scope of this grade variable? Just within the foreach?
