wcscmp() function in C++ with Examples

The wcscmp() function is defined in cwchar.h header file. The wcscmp() function is used to compares two null terminating wide string and this comparison is done lexicographically.


int wcscmp(const wchar_t* str1, const wchar_t* str2);

Parameters: This method takes the following two parameters:

Return Value: This method returns:

Below programs illustrate the above function:-

Example 1:-





// c++ program to demonstrate
// example of wcscmp() function.
#include <bits/stdc++.h>
using namespace std;
int main()
    // initialize the str1
    wchar_t str1[] = L"Computer";
    // initialize the str2
    wchar_t str2[] = L"Science";
    // Compare and print results
    wcout << L"Comparing " << str1 << L" and "
          << str2 << L" = " << wcscmp(str1, str2) << endl;
    // Compare and print results
    wcout << L"Comparing " << str2 << L" and "
          << str2 << L" = " << wcscmp(str2, str2) << endl;
    // Compare and print results
    wcout << L"Comparing " << str2 << L" and "
          << str1 << L" = " << wcscmp(str2, str1) << endl;
    return 0;

Comparing Computer and Science = -1
Comparing Science and Science = 0
Comparing Science and Computer = 1
