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...

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... ...

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...
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 ...

In previous versions,_mbctolowerwas calledjtolower, and_mbctoupperwas calledjtoupper. For new code, use the new names instead. By default, this function's global state is scoped to the application. To change this behavior, seeGlobal state in the CRT. ...
