The wcsstr() function is defined in cwchar.h header file. The wcsstr() function finds the first occurrence of a source in a destination string.
Syntax:
wchar_t* wcsstr(const wchar_t* dest, const wchar_t* src);
Parameter: This method accepts the following parameters:
- src: It represents the pointer to the null terminating wide string to be search for.
- dest: It represents the pointer to the null terminating wide string in which we have to search.
Return Value: The return value of this method depeneds on:
- If src is not found than it returns NULL
- If src points to an empty string then destination is return
- If the src is found, the wcsstr() function returns the pointer to the first wide character of the src in dest.
Below program illustrate the above function:
Example 1: When the source is not found, null is returned
// c++ program to demonstrate // example of wcsstr() function. #include <bits/stdc++.h> using namespace std; int main() { // initialize the destination string wchar_t dest[] = L"Geeks Are Geeks"; // get the source string to be found wchar_t src[] = L"To"; // Find the occurrence and print it wcout << wcsstr(dest, src); return 0; } |
Example 2: When the source is empty, destination string is returned
// c++ program to demonstrate // example of wcsstr() function. #include <bits/stdc++.h> using namespace std; int main() { // initialize the destination string wchar_t dest[] = L"Geeks Are Geeks"; // get the source string to be found wchar_t src[] = L""; // Find the occurrence and print it wcout << wcsstr(dest, src); return 0; } |

Example 3: When the source is found, the destination from the source is returned.
// c++ program to demonstrate // example of wcsstr() function. #include <bits/stdc++.h> using namespace std; int main() { // initialize the destination string wchar_t dest[] = L"Geeks Are Geeks"; // get the source string to be found wchar_t src[] = L"Are"; // Find the occurrence and print it wcout << wcsstr(dest, L"Are"); return 0; } |
