    <p>Using Visual Studio, its an exercise, I need to add other students in, which isn't a problem. My main question is: I want the code to jump back to the input question if the value is above 100 or below 0 included, but I don't know the code that checks(validates) the user-input, any help would be very helpful and I would be incredibly grateful.</p> <pre><code>using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace Student_Marks_For_Statement { class Program { static void Main(string[] args) { char moreData; double total = 0; double secondTotal = 0; for (double student1 = 0; student1 == 0; student1++) { Console.Write("Enter mark for student 1: "); student1 = Convert.ToDouble(Console.ReadLine()); total += student1; Console.WriteLine("Any more data? Enter 'y' or 'n' then return"); moreData = Convert.ToChar(Console.ReadLine()); if (moreData == 'n') { ; } if (moreData == 'y') { Console.Write("Enter Value :"); secondTotal = Convert.ToDouble(Console.ReadLine()); total += secondTotal; } for (double student2 = 0; student2 == 0; student2++) { Console.Write("Enter mark for student 2: "); student2 = Convert.ToDouble(Console.ReadLine()); total += student2; student2++; Console.WriteLine("Any more data? Enter 'y' or 'n' then return"); moreData = Convert.ToChar(Console.ReadLine()); if (moreData == 'n') { ; } if (moreData == 'y') { Console.Write("Enter Value :"); secondTotal = Convert.ToDouble(Console.ReadLine()); total += secondTotal; student2++; } Console.WriteLine("Total marks = : {0}", total); } } } } } </code></pre>

    1. COCould you at the very least give your question a descriptive title? That you need help is obvious, but it tells us nothing about the question you're about to ask.

    2. COHow about using methods? If you lazy you can use "goto" but thats very very very bad practice.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
