资料码 (data code):条码的主要部份,又因使用不同,编码方式也不同. 检查码 (check code):又称查核码,用计算公式算出,以确保资料正确性. 终止码 (end code):一个条码的结束,以便条码读取器判别结束.

Developers can use coverage reports to check code quality before attempting to modify it.
开发人员可以在试图修改代码之前使用覆盖报告来检查代码质量。
A developer cannot check code into the source code repository until all the unit tests pass.
开发人员只有在通过所有单元测试后才可以将代码检入到源代码资源库中。
To see just how effective my tests are at exercising the code, I can check code coverage with Hansel.
为了看看上述测试在检验这块代码时效果如何,我可以用Hansel检查代码覆盖情况。
If I come into this code, I'm going to check this branch first, if it's not true, ah, there's a return at the end of that branch. If it is true, I do that, and then I've got a second test. If it's true, return I return, otherwise a return.
但是如果我们看看这里,如果我看这段程序,我会先检查这一部分,如果它是假的,啊,这部分分支结尾有一个。
And just to look ahead a little bit, you could easily imagine that I might want to not just put a statement in there, what the specs are, I might want to put some constraints. Some specific things to check for, to make sure that you're calling the code right.
这不仅是抽象的概念还有规范的概念,我们再往前看看,你可以简单的想象得到,我不仅仅是想在这里加一个声明,这些规范说明中我还想加一些约束,我们要注意一些特殊的事情。
include stdio h The next line of code says include standard io.h which just as a little sanity check contains among other things, printf.
接着的一行代码写着,这个库文件包含一些我们常用的函数,譬如,printf函数。
