References  Kernighan, B. If a file is in reading mode, then no data is deleted if a file is already present on a system. These two functions are used to handle only a single character at a time. Following are the different types of modes in 'C' programming which can be used while working with a file. This prevents accidental damage to the file. A file must be opened before performing operations on it. Usage notes and limitations: The formatSpec parameter must be constant. After a write operation is performed, then the file is closed using the fclose function. If fileID has a constant value of 1 or 2 and extrinsic calls are not possible, the code generator produces a C printf call.
Getc and putc functions are used to read and write a single character. Summary A file is a space in a memory where data is stored. Keep in mind that as with scanf, fscanf stops reading a string when space or newline is encountered.
