The correct function to convert a C-string to an integer in C++ is atoi. This function takes a C-string as input, ignores any leading white space characters (such as spaces, tabs, and newlines), and then reads in all numeric characters until it reaches the end of the string, converts them to an integer value, and returns that integer value. Therefore, option D is correct.
