Function Details : wcscat

wchar_t *wcscat(wchar_t * dest,const wchar_t * src) ;

Return Type : wchar_t *

A pointer to a wide-character string, where each element is of type `wchar_t`. Used for representing text in wide-character encoding to support extended character sets.
Read about return values of wcscat function .

1st Parameter Type : wchar_t *

A pointer to a wide-character string, where each element is of type `wchar_t`. Used for representing text in wide-character encoding to support extended character sets.

1st Parameter

Pointer to the destination wide-character string. This string must have enough space to hold the concatenated result, including the null terminator.

2nd Parameter Type : const wchar_t *

A pointer to a read-only wide-character string, where each character is of type `wchar_t`. Used for representing text in wide-character encoding to support extended character sets, such as Unicode. The string is null-terminated, with the terminator being a `wchar_t` with value 0.

2nd Parameter

Pointer to the source null-terminated wide-character string to be appended to `dest`.

The wcscatfunction in C language Appends a wide character string to the end of another wide character string.
wcscat appends a copy of the wide character string pointed to by src (including the terminating null wide character) to the end of the wide character string pointed to by dest. The initial wide character of src overwrites the null wide character at the end of dest. The behavior is undefined if the destination array is not large enough to hold both strings.
The wcscatfunction takes 2 parameters:
  • •
    wchar_t * `dest`: Pointer to the destination wide-character string. This string must have enough space to hold the concatenated result, including the null terminator.
  • •
    const wchar_t * `src`: Pointer to the source null-terminated wide-character string to be appended to `dest`.
Appends the wide-character string `src` to the end of the wide-character string `dest`. The resulting string in `dest` is null-terminated. The behavior is undefined if the destination buffer is not large enough to hold the resulting string, or if the strings overlap. Returns a pointer to `dest`.
The wcscat function return value :
  • Returns a pointer to the destination string dest

Output

This example demonstrates the basic usage of wcscat to concatenate two wide character strings.
