4. Moore's law, which predicted that the number of devices integrated on a chip would be doubled every two years, was accurate for a number of years.

摩尔定律指出：集成在一个芯片上的器件数量将每两年翻一番。这在许多年来都是正确的。

五、综合运用（每小题20分，共20 分）

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.

(将上面的短文翻译成中文)

与Pascal语言相似，C通常被看成是一种结构化语言。在C语言中，一个代码块是一组逻辑上相联系的程序语句，它们可以被看成是一个单元（块）。你可以在左右两个花括号之间插入几行代码创建一个代码块。如：

if(x<10)

{

printf (“too low, try again”);

reset_counter(-1);

}

如果x小于10，if 后面的位于花括号之间的两个语句就被执行。这两个句子连同两个花括号表示一个代码块，这两个语句是连系在一起的：不可能只执行其中一个语句，而不执行另一个语句。
