Question

Given the data assigned to the string variable str2 shown below, which of the following statements will assign the value ALL to the string variable str1?
 str2 = "WHEN ALL ELSE FAILS, READ THE DIRECTIONS"
A) str1 = str2.Substring(5)
B) str1 = str2.Indestr1OfStr("ALL")
C) str1 = str2.Substring(6, 3)
D) str1 = str2.Substring(5, 3)

Quizplus · Accepted Answer

Option A (str1 = str2.Substring(5)) would assign the value "ALL ELSE FAILS, READ THE DIRECTIONS" to str1, because Substring(5) starts at index 5 (which is the "A" in "ALL") and includes all characters to the end of the string. 
Option B (str1 = str2.Indestr1OfStr("ALL")) is incorrect because there is no method in C# called Indestr1OfStr(). 
Option C (str1 = str2.Substring(6, 3)) would assign the value "ELS" to str1 because Substring(6, 3) starts at index 6 and includes the next 3 characters. 
Option D (str1 = str2.Substring(5, 3)) is correct because Substring(5, 3) starts at index 5 (which is the "A" in "ALL") and includes the next 3 characters, resulting in the value "ALL".
