input file stream objects are declared using the ifstream class in C++. The ifstream class allows reading data from a file, making it the appropriate choice for input stream operations. The other choices - istream, iofstream, and ofstream are used for general input/output, output file operations, and general file input/output, respectively. The correct type for input file stream objects is ifstream. istream is a more general stream type that can be used for input from various sources, including standard input. iofstream is not a valid type, and ofstream is used for output file stream objects.
