该函数还支持使用参数的样式表。
使用参数标记发出sql语句。
实际命令行程序使用参数。
So all of these programs or commands that we've been using thus far for the piece set in class, take what we call command line arguments, they are the zero or more words that follow the program's name.
所有我们一直在课堂上使用的,这些程序或者命令,携带着命令行参数,它们是跟在,程序名的后面的一个或多个单词。
Indeed, swap in your printout there is just defined as now taking *a and *b and then it also uses the * later, but we'll come back to what the different uses of the * means, but for now I claim conceptually it just means swap has access to the locations of its parameters.
的确,在打印资料中的swap被定义为,携带*a和*b,之后它也是带*号的,但是我们将说明*的不同用法,现在,我断言swap可以,使用参数的地址。
First of all, two parameters. It's OK. All it says is, when I call this, I need to pass in two parameters for this to work. All right? Now, if I want to use that, I'm going to use a second piece of code here, called Barnyard. I'm going Barnyard to read in a couple of values, convert them into integers, and then I'm going to use solve to get a solution out.
注意我得到了什么,第一,两个参数,它的意思就是我调用这个函数,我得给它输入两个参数,明白了吗?,现在如果我要使用它我得用,这里的第二段代码,也叫,我将读入一组值,将它们转化为整型,然后我会用solve得到一个解决方案。
