Computer Programming 1 Quiz No. 1

Explanation
The given answer "COMPROG1" suggests that the result of the method "Clone()" in the COMPROG1 class is itself, meaning that when the Clone() method is called on an instance of COMPROG1, it creates a new instance that is an exact copy of the original instance.

Explanation
The given question is incomplete as it does not provide any information about the initial content of COMPROG1. Therefore, it is not possible to generate an explanation for the correct answer.

Explanation
The given string "COMPROGramming" is passed to the Replace() function with the parameters "1" and "ramming". This means that all occurrences of "1" in the string will be replaced with "ramming". Therefore, the result of the Replace() function will be "COMPROGramming" with "1" replaced by "ramming", resulting in "COMPROGramming".

Explanation
The result of COMPUTER.PROGRAMMING.Length is 20.

Explanation
The result of "computer programming.ToLower()" is "computer programming" because the ".ToLower()" method is used to convert all the characters in a string to lowercase. However, since the original string "computer programming" already consists of lowercase characters, applying the ".ToLower()" method does not change the string and returns the same string as the result.

Explanation
The result of COMPROG1.StartsWith("c") is False because the method checks if the string starts with the specified character or substring. In this case, "c" is not the starting character of COMPROG1, so the result is False. The answer is given in three different forms (False, false, FALSE) to show that the result can be represented in different ways depending on the programming language or context.

Explanation
The result of COMPROG1.Contains("o") is False,false,FALSE. This is because the Contains() method is case-sensitive and checks for the exact match of the specified substring "o" in the string COMPROG1. Since none of the characters in COMPROG1 match "o", the result is False for all three cases (False, false, and FALSE).

Explanation
The EndsWith() method in COMPROG1 is used to check if a string ends with a specified character or sequence of characters. In this case, the specified character is "1". The result of the EndsWith("1") method will be true for all three cases - True, true, and TRUE - because all of them end with the character "1".

Explanation
The given code "computer programming.ToUpper()" is attempting to convert the string "computer programming" to uppercase. Since the string is already in uppercase, the result of the code will be the same string "COMPUTER PROGRAMMING".

Explanation
The result of the LastIndex function is 5. This means that the last occurrence of the character "O" in the string COMPROG1 is at index position 5.
