Although C++ can not uppercase or lowercase a string, it can uppercase or lowercase an individual character, using the toupper() and tolower() standard functions respectively. This means we need to be able to isolate the characters of a string so we can apply the toupper() or tolower()...
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 ...
ToLowerCase() 使用預設地區設定的規則,將此String中的所有字元轉換成小寫。 ToLowerCase(Locale) 使用指定Locale的規則,將這個String中的所有字元轉換成小寫。 ToLowerCase() 使用預設地區設定的規則,將此String中的所有字元轉換成小寫。 C# [Android.Runtime.Register("toLowerCase","()Ljava/lang/String;","...
* The functions toUpperCase and toLowerCase return a new string whose * characters appear in the desired case. These implementations rely on * the fact that the characters in the string are copied when the * argument is passed to the function, which makes it possible to change * the case ...
