Compound Statements (Blocks)
A compound statement, or block, is a list (possibly empty) of statements enclosed
in matching braces
{}
. Syntactically, a block can be considered to be a single
statement, but it also plays a role in the scoping of identifiers. An identifier
declared within a block has a scope starting at the point of declaration and ending
at the closing brace. Blocks can be nested to any depth up to the limits of memory.
For example,
for
loop expects one statement in its body, so we can pass it a com-
pound statement:
for (i = 0; i < n; i++) {
int temp = a[i];
a[i] = b[i];
b[i] = temp;
}
Note that, unlike other statements, compound statements do not end with semi-
colon (
;
), i.e. there is never a semicolon following the closing brace.
