Web1.3 函数重载调用准则. 函数重载调用时，先去找名称相同的函数，然后进行参数个数和类型的匹配。. 找不到匹配的函数就会编译失败，找到两个匹配的函数也会编译失败；. 重载的的函数，本质是两个不同的函数，在静态链编的时候就编链成两个不同的函数 ...

WebLike all other functions from , the behavior of std::tolower is undefined if the argument's value is neither representable as unsigned char nor equal to EOF. To use these functions safely with plain char s (or signed char s), the argument should first be converted to unsigned char : char my_tolower (char ch) { return static_cast first time user ccp
