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.
