The first line of the program has a preprocessing directive, indicated by #include. This causes the compiler to switch that line with your entire textual content on the stdio.h standard header, which incorporates declarations for traditional enter and output capabilities for example printf.
Considering that many programs have been created in C, you will discover a wide variety of other libraries readily available. Libraries tend to be prepared in C mainly because C compilers make successful item code; programmers then create interfaces on the library so that the routines can be used from higher-degree languages like Java, Perl, and Python.
