Question

Extract errors from the following codes & then obtain weather they are Syntax
Error or Run Time Error? [15 pts]
a) [2 pts]
1 Dim number1 As Integer
2 Dim number2 As Integer
3 Dim result As Integer
4
5 number1 = (4 * 6 ^ 4) / (10 Mod 4 – 2)
6 number2 = (16 \ 3) ^ 2 * 6 + 1
7 result = number1 - number2

Line# / Error Description /Error Type (Syntax or Runtime) /Correction

b) [4pts]
1 Dim number1 As Double
2 Dim number2 Double
3 Dim result As Char
4
5 number1 = (4 ^ 2)
6 number2 = (16 \ 2)
7 result = number1 \ number2

Line# /Error Description /Error Type (Syntax or Runtime) /Correction

Answer 1

Hi,

In the first Expression,

There is a Compile Time Error and this is caused because of the below statement:

Error at line no - 5

Error description/Type - Compile Time Error

Correction:

number1 = (4 * 6 ^ 4) / (10 Mod 4 – 2)

To resolve this, you can replace

number1 = (4 * (6 ^ 4) / (10 Mod 4)) - 2

Note: Divider should more than 0 so above statement will wok because

1. 10 Mod 4 - 2 will return 0
2. (10 Mod 4) - 2 also returns 0
3. 10 Mod (4-2) also returns 0

=============================================================================

In the second Expression:

Error Line no - 2

Error Description - End of statement expected - Compile Time Error

Correction: To resolve the above error we need to declare the variable as below:

Dim number2 As Double

Again You can observe that Erro Line no - 7

Error Description: 'Long' value cannot be converted to 'char' - Compile time

Correction: result = Convert.ToChar(number1 \ number2)

Thanks
