Question 1:

Module VBModule
 
    Sub Main()
        dim num1 as SDouble=-10.34
        dim num2 as UShort=20
        
        Console.WriteLine("Num1: {0}",num1)
        Console.WriteLine("Num2: {0}",num2)
    End Sub
    
End Module

Output:

main.vb (4,28) : error VBNC30451: 'SDouble' is not declared. It may be inaccessible due to its protection level.
There were 1 errors and 0 warnings.

Explanation:

The above program will generate a syntax error because there is no SDouble data type in VB.NET.

Question 2:

Module VBModule
 
    Sub Main()
        dim num1 as Double=-10.34
        dim num2 as SByte=128
        
        Console.WriteLine("Num1: {0}",num1)
        Console.WriteLine("Num2: {0}",num2)
    End Sub
    
End Module

Output:

Unhandled Exception:
System.OverflowException: Arithmetic operation resulted in an overflow.

Explanation:

The above program will generate an exception, here we tried to initialize variable num2 with 128, which will create an overflow exception because we can store a value between -128 to 127 in a Signed Byte variable.

---

Question 3:

Module VBModule
 
    Sub Main()
        dim num1 as Double=-10.34
        dim num2 as SByte=128
        
        Console.WriteLine("Num1: {0}",num1)
        Console.WriteLine("Num2: {0}",num2)
    End Sub
    
End Module

Output:

Unhandled Exception:
System.OverflowException: Arithmetic operation resulted in an overflow.

Explanation:

The above program will generate an exception, here we tried to initialize variable num2 with 128, which will create an overflow exception because we can store values between -128 to 127 in a Signed Byte variable.

Question 4:

Module VBModule
 
    Sub Main()
        Console.WriteLine("Size of Double: {0}",len(Double))
        Console.WriteLine("Size of Single: {0}",len(Single))
    End Sub
    
End Module

Output:

main.vb (4,59) : error VBNC99999: <no message written yet>

/home/cg/root/62a5b665d3a94/main.vb (5,59) : error VBNC99999: <no message written yet>

There were 2 errors and 0 warnings.

Explanation:

The above program will generate syntax errors because we cannot get the size of the datatype using the len() method.

---

Question 5:

Module VBModule
 
    Sub Main()
        dim num1 as Single = 10.23
        dim num2 as Double = 10.45
        dim num3 as UShort =  25
        
        dim res as Double =  0.0
        
        res = (len(num1) * len(num2))/len(num3)
        
        Console.WriteLine("Result: {0}",res)
        
    End Sub
    
End Module

Output:

Result: 16

Explanation:

In the above program, we created 3 variables. Then we used the len() function to get the length of the variables.

Now we evaluate the expression:

res = (len(num1) * len(num2))/len(num3)
res  = (4 * 8)/2
res = 32/2
res = 16
