五、综合运用（每小题 20分，共 20

C is commonly considered to be

a structured language with some similarities to Pascal. In C, a block of code is a logically connected group of program statements that can be treated as a unit. You can create a block of code

by placing lines of code between opening and closing curly braces. For example:

if(x<10)

{

printf (“too low,

try again”);

reset_counter(-1);

}

The two statements after "if" that are between the curly braces are executed if x is less than 10. These two statements with the braces represent a block of code. They are linked together: one of the statements cannot execute without the other also executing.
