Compound Statements (Blocks)

A compound statement, or block, is a list (possibly empty) of statements enclosed
in matching braces
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,
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 (

loop expects one statement in its body, so we can pass it a com-
