wcsncpy() function in C++The wcsncpy() function is actually a C Standard Library function and is not a part of C++. The "wcs" prefix stands for "wide character string", indicating that it is used for handling wide character strings, which are typically used in internationalization and Unicode support. Let's examine wcsncpy() in greater detail: Syntax:It has the following syntax: wchar_t* wcsncpy(wchar_t* destination, const wchar_t* source, size_t num); Destination: A pointer to the destination array where the content will be copied. Source: A pointer to the source of the data to be copied. Num: The maximum number of wide characters to copy. Behavior:
If num is greater than or equal to the length of the source string, wcsncpy() does not guarantee the null-termination of the destination string. If you want null-termination, you may need to add it explicitly to the destination array after using wcsncpy(). Example 1:Let's take an example to illustrate the use of the wcsncpy() function in C++. Output: Explanation: In this example, the destination array is explicitly null-terminated after the wcsncpy() function copies a maximum of ten wide characters from the source string to the destination array. After that, std::wcout is used to print the outcome. Example 2:Let's take another example to illustrate the use of the wcsncpy() function in C++. Output: Example 3:Let's take an example to illustrate the use of the wcsncpy() function in C++. Output: Example 4:Let's take an example to illustrate the use of the wcsncpy() function in C++.
