Predictably, equivalents to gets and puts exist called fgets and fputs. The programmer should be careful in using them, since they are incompatible with gets and puts. gets requires the programmer to specify the maximum number of characters to be read. fgets and fputs retain the trailing newline character on the line they read or write, wheras gets and puts discard the newline.
When transferring data from files to standard input / output channels, the simplest way to avoid incompatibility with the newline is to use fgets and fputs for files and standard channels too.
For Example, read a line from the keyboard using
fgets(data_string, 80, stdin);
and write a line to the screen using
Go to Formatted I/O with Strings Go to Index Go to Special Characters
