Which function is used to replace a single target character with a replacement character?

1. ReplaceFirst()

2. ReplaceChar()

3. Replace()

4. CharReplace()

The correct answer is: ReplaceChar()

The function that is used to replace a single target character with a replacement character is characterized by its focus on modifying specific characters within a string. In this context, the function named ReplaceChar() directly aligns with this purpose, as the nomenclature suggests a clear intention of substituting one character for another. ReplaceChar() is particularly useful when there is a need to target a specific character in a string and replace it with a designated alternative. This function provides straightforward functionality for character manipulation, making it an essential tool for tasks involving text processing and string management. Other options may include functions that serve different purposes, such as replacing multiple occurrences or entire substrings, but they do not specifically emphasize the singular character replacement task that is fundamental to the question's requirement. By focusing on replacing individual characters, ReplaceChar() is the appropriate choice for this functionality.
