这与将它们声明为整型变量一样容易。

They are as easy to declare as integer variables.

这里我们将为字数统计程序声明一个整型变量，来保存程序统计出来的字数。

We will declare an integer variable here for our word-counting program that holds the number of words counted by the program.

youdao

So this declares an integer, a variable of type int called I, 0 and initializes it to zero.

所以这里声明了一个整型数，一个叫做I的整型变量，把它初始化为。
