问题描述
我正在学习C ++，所以请善待。有什么地方我可以吗？
查看toUpper函数的源代码？谢谢。
I am learning C++, so please be kind. Is there anywhere that I can
view the source code for the toUpper function? Thanks.
推荐答案
您可以下载带GCC的标准C库。
You can download the standard C library with GCC.
没有来源。只要行为符合标准要求，每个实现都可以自由地将它写成
方式。
例如，使用ASCII的人可能会看一眼它的当前值
如果当前处于小写状态，则设定一个设定值。范围。
尝试搜索toupper.c以找到一些实现。

There is no "the source". Each implementation is free to write it the
way they want, as long as the behavior is what the standard requires.
For instance, one that uses ASCII might take a peek its current value
and subject a set value if its currently in the "lowercase" range.
Try doing a search for toupper.c to find some implementations.

从未听说过上午。
看看ctype.h的C答案并注意toupper（。 ..）
根据< cctype>成为std :: toupper（...）。
Never heard of toUpper.
Take a look at ctype.h for a C answer and note that toupper(...)
becomes std::toupper(...) according to <cctype>.
