Equal Sign
The equal sign (
=
) separates variable declarations from initialization lists:
int
test[5] = {1, 2, 3, 4, 5};
int
x = 5;
The equal sign is also used as the assignment operator in expressions:
int
a, b, c;
a = b + c;
For more information, see Assignment Operators.
Pound Sign (Preprocessor Directive)
The pound sign (
#
) indicates a preprocessor directive when it occurs as the first
nonwhitespace character on a line. It signifies a compiler action, not necessarily
associated with code generation. See Preprocessor Directives for more informa-
tion.
associated with code generation. See Preprocessor Directives for more informa-
tion.
#
and
##
are also used as operators to perform token replacement and merging
during the preprocessor scanning phase. See Preprocessor Operators.
