Nested Blocks

• The scope of a variable includes nested blocks, i.e., blocks that appear within the block in which the variable is declared.

{

int a = readInt();

int b = readInt();

if (a > b)

{

int temp = a;

a = b;

b = temp;

}

. . .

}

• Thus, a and b are meaningful within the inner block, but temp is not meaningful in the outer block.
