Identify the built-in function used for reading a string from the keyboard.printreadinputintstr

The built-in function commonly used for reading a string from the keyboard in various programming languages is typically input(). This function prompts the user to enter data and then captures the input as a string.

Explanation:

1. Function Name: The function is called input().
2. Usage: When you call input(), the program waits for the user to type something and hit Enter.
3. Return Value: The value returned by input() is always a string, regardless of what the user types.
4. Syntax Example:

   user_input = input("Please enter a string: ")
   

5. Variation: In some languages, such as C, you would use scanf() with the format specifier %s, but in most high-level languages, input() is the standard method.

In summary, if you're working in a language like Python, the function you would utilize is input() to read a string from the keyboard.
