10、ascal. 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(x10) 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. (将上面的短文翻译成中文)姓名 系别 班级 学号 命题人
