Question

Assume the following declaration appears in a program: Declare String str = "Tiger" Write a statement that changes the str variable's first character to \(^{*} \mathrm{L}^{\prime \prime}\)

Short answer

Answer: The steps involved in changing the first character of the given string "Tiger" to "L" are: 1. Identify the given string, which is "Tiger". 2. Extract everything but the first character from the original string, resulting in "iger". 3. Combine the desired new character "L" with the remaining string "iger" to get the modified string "Liger". 4. Assign the new string to the original variable 'str'.

Step-by-step solution

Identify the given string

The given string is "Tiger". Here is its declaration: Declare string str = "Tiger"

Extract the first character from the original string

To change the first character, first extract everything but the first character, which is "iger" in this case. This can be done using the substring function that most programming languages provide: Declare string remainingString = str.Substring(1)

Combine the new character with the remaining string

Now, combine the desired new character "L" with the remaining string "iger" to get the modified string "Liger": Declare string modifiedString = "L" + remainingString

Assign new string to the original variable

Finally, assign the new string to the original variable 'str': str = modifiedString
