The general form of a C program is as follows:
pre-processor directives
global declarations
main()
{
local variables to function main ;
statements associated with function main ;
}
f1()
{
local variables to function 1 ;
statements associated with function 1 ;
}
f2()
{
local variables to function f2 ;
statements associated with function 2 ;
}
.
.
.
etc
Note the use of the bracket set ()
and {}. () are used in conjunction with function names whereas {} are used as
to delimit the C statements that are associated with that function. Also note
the semicolon - yes it is there, but you might have missed it! a semicolon (;)
is used to terminate C statements. C is a free format language and long statements
can be continued, without truncation, onto the next line. The semicolon informs
the C compiler that the end of the statement has been reached. Free format also
means that you can add as many spaces as you like to improve the look of your
programs.
