Comment Lines
A C source program consists of statements and comment lines. Comment lines
are enclosed by the characters /* ( at the start of the comment) and */ (at the end
of the comment).
(5)The Function main()
Every C program must have a function called main
which must appear only
once in a program. The parentheses following the word main must be present,
ut there must be no parameters included. The main part of the program is
enclosed within
aces {}, and consists of declaration statements, assignment
(10)statements within
aces; a declaration statement ( the first statement of the
main program starting with the word
float ), two assignment statements ( the
fourth and fifth statements starting with the variable names d and average ), and
three function statements, two to print information on the screen and one to scan
the keyboard for input.
(15)
As C is a free form language, the semicolon (;) at the end of each line is a
must. It acts as a statement terminator. Telling the complier where an
instruction ends. Free form means that statements can be identified and blank
lines inserted in the source file to improve readability, and statement can span
several lines. However, each statement must be terminated with a semicolon. If
(20)you forger to include the semicolon, the complier will produce an e
or,
indicating the next line as the source of the e
or. This can cause some
confusion, as the statement objected can be co
ect, yet as a syntax e
or is
produced.
Variables and the Declaration Statement
(25)A variable is quantity that is refe
ed to by name, such as a, b, c and
average in the above program. It can take on many values during program
execution, but you must make sure that they are given an initial value, as C does
not do so automatically. However, before variables can be used in a program,
they must be declared in a type declaration statement.
A. Complete the sentences:
1. The function ________ must appear only once in a program.
2. /* CALULATE AVERAGE */
is a _______ line.
