Question

Given the following code fragment, what is the ultimate value of variable output?

Dim str1 As String = "pro"

Dim str2 As String = "baseball"

Dim output As String = "MLB"

Dim myVal As Integer = 5

output = str2.Substring(0,1)

-Please provide the answer and how you got it Thank you.

Answer 1

Answer: b

Dim str1 As String = "pro"

Dim str2 As String = "baseball"

Dim output As String = "MLB"

Dim myVal As Integer = 5

output = str2.Substring(0,1)

In line 1 str1 String variable intialized with value "pro"

In line 2 str2 String variable intialized with value "baseball"

in line 3, output String variable intialized with value "MLB"

in line 4, myVal Integer variable intialized with value 5

in line 5, we are assigning str2 variable substring value to output variable

str2.Substring(0,1) will return value b. Substring(0,1) mwthod will look for the first character in string str2.

so output variable will be assigned with value "b".
