cout<< (char)tolower(c1) <<endl; 在这里,我们使用代码(char) tolower(c1)将tolower(c1)的返回值转换为char。 另请注意,最初: c2 = 'b'等tolower()返回相同的值 c3 = '9'等tolower()返回相同的值 示例2:没有类型转换的 C++ tolower() #include<cctype>#include<iostream>usingnamespacestd;intm...

char my_tolower(char ch) { return static_cast<char>(std::tolower(static_cast<unsigned char>(ch))); }类似地,迭代器的值类型为 char 或signed char 时,不应直接将它们用于标准算法。而是要首先转换值为 unsigned char: std::string str_tolower(std::string s) { std::transform(s.begin(), s...
Defined in header <cctype> int tolower( int ch ); 根据当前安装的C语言环境定义的字符转换规则将给定字符转换为小写。 在默认的“C”区域设置中,以下大写字母ABCDEFGHIJKLMNOPQRSTUVWXYZ被替换为相应的小写字母。abcdefghijklmnopqrstuvwxyz... ...
In this case, we created a functiontoLowerthat takeschar*, where a null-terminated string is stored and asize_ttype integer denoting the string’s length. The function allocates the memory on the heap using thecallocfunction; thus the caller is responsible for deallocating the memory before ...

The version of this function without the _l suffix uses the current locale for this locale-dependent behavior; the version with the _l suffix is identical except that it uses the locale parameter passed in instead. For more information, see Locale. In previous versions, _mbctolowe...
