To capitalize the first letter of each word in a string, which function would you use?

1. ToTitle()

2. TitleCase()

3. Capitalize()

4. UpperCase()

The correct answer is: TitleCase()

The function that converts the first letter of each word in a string to uppercase is indeed the TitleCase function. This function is specifically designed to apply title casing to a provided string, ensuring that the first letter of each word is capitalized, while the rest of the letters remain in their original case unless further specified. Using TitleCase is particularly useful for formatting titles or headings where proper nouns should be emphasized. This function processes the string intelligently, identifying word boundaries and applying the capitalization where appropriate, which aligns well with common title formatting practices. Other functions, while they may manipulate text, do not achieve the same result as TitleCase. For instance, functions like ToTitle() and Capitalize() exist, but they do not specifically perform the same operation of capitalizing the first letter of each word. UpperCase, on the other hand, converts all characters in the string to uppercase without regard to word boundaries. Therefore, TitleCase is the correct choice for capitalizing the first letter of each word in a string.
