Which of the following statements is true about the ReplaceChar() function?

1. It replaces all instances of a character

2. It replaces the first occurrence of a character

3. It replaces a single target character with a specified character

4. It capitalizes all characters in a string

The correct answer is: It replaces a single target character with a specified character

The ReplaceChar() function is designed to replace a specific target character in a string with a character that you specify. This functionality allows for targeted alterations within strings, making it a useful tool for tasks such as data cleansing or formatting where certain characters need to be altered while leaving other parts of the string intact. For example, if you use ReplaceChar() to transform every instance of a lowercase letter 'a' into an uppercase letter 'A' in a given string, only the target instances of 'a' are replaced, leaving all other characters unchanged. This precise, one-to-one replacement is what distinguishes this function in handling character replacements specifically, rather than more general replacements such as all occurrences or manipulation that involves capitalizing characters.
