Here I will show how to use some the ifstream, and iostream functions.

Code	Output
	No Output
Bit test (ios::) Description eofbit This is set when the end of a input stream has been reached. failbit Set when an operation on a bit has failed. hardfail This is set when a fatal, unrecoverable error has occurred. badbit This is set when an invalid operation has been attempted. goodbit This is set when a attempted operation is successful.
Function Description eof() Returns true if the End Of File is found. fail() Returns true if a failbit or hardfail is found, and is set. bad() Returns true if a bad bit is found, and badbit is set. good() Returns true if the bit is good, and goodbit is set. clear() Clears all flags from stream.
