"A teacher has given a test to his class. He would like to have the average score for the class, and the highest and lowest scores."

Private Sub Command1_Click()
Cls
Sum = 0
lowest = 9999
highest = 0
stu = InputBox("Enter Total Number of Students in the class:")
For i = 1 To stu
marks = InputBox("Enter Marks of Student")

If highest < marks Then
highest = marks
End If

If lowest > marks Then
lowest = marks
End If

Sum = Sum + marks
Next
Avg = Sum / stu
Print "Average Score: ", Avg
Print "Highest Score: ", highest
Print "Lowest Score: ", lowest
End Sub

This is a C++ forum.
I suggest you try a VB forum.

I just want to know if there is any flaw in the logic. I have joined this forum because i am doing master in computer science and we will study c++ in 2-3 weeks time. Meanwhile we are given these problems to solve (just algorithm and flowchart). So i am checking my algorithms on visual basic. If its against rules plz tell me. I will refrain asking questions like these.
