The clearerr() function in C is a standard library function that clears the error and end-of-file indicators for the specified stream. It is part of the C standard library (stdio.h) and is used to reset the error and EOF states of a stream.
The gets() function in C is a standard library function that reads a line from the standard input stream (stdin) and stores it into the string pointed to by str. It is part of the C standard library (stdio.h). However, gets() has been deprecated and removed in the latest C standards due to its unsafe …
The getchar() function in C is a standard library function that reads the next character from the standard input stream (stdin) and returns it as an unsigned char cast to an int. It is part of the C standard library (stdio.h) and is commonly used for reading characters from the user input.
