The wcsncat() function appends the characters of the source to the destination, including a terminating null wide character. If the length of the string in source is less than num. Then only the content up to the terminating null wide character is copied.
Syntax:
wchar_t* wcsncat (wchar_t* destination, const wchar_t* source, size_t num)
Parameters: The function accepts three mandatory parameters which are described below:
- destination: specifies the pointer to the destination array
- source: specifies the string to be added to the destination
- num: specifies the maximum number of character to be added
Return value: The function returns the destination.
Below programs illustrate the above function:
Program 1:
// C++ program to illustrate // wcsncat() function #include <bits/stdc++.h> using namespace std;
int main()
{ // maximum length of the destination string
wchar_t destination[20];
// maximum length of the source string
wchar_t source[20];
// initialize the destination string
wcscpy(destination, L "Geekforgeeks " );
// initialize the source string
wcscpy(source, L "is the best" );
// initialize the length of
// the resulted string you want
wcsncat(destination, source, 20);
wprintf(L "%ls\n" , destination);
return 0;
} |
Output:
Geekforgeeks is the best
Program 2 :
// C++ program to illustrate // wcsncat() function #include <bits/stdc++.h> using namespace std;
int main()
{ // maximum length of the destination string
wchar_t destination[40];
// maximum length of the source string
wchar_t source[40];
// initialize the destination string
wcscpy(destination, L "only some of the " );
// initialize the source string
wcscpy(source, L "letters will be copied" );
// initialize the length of
// the resulted string you want
wcsncat(destination, source, 20);
wprintf(L "%ls\n" , destination);
return 0;
} |
Output:
only some of the letters will be copi
