Examples at hotexamples.com: 4

The wstring find method in C++ searches for a specified substring within a string and returns the position of the first occurrence. It takes the substring to search for as an argument and returns npos if the substring is not found.

Example 1: Searching for a substring within a string

#include 
#include 

int main()
{
    std::wstring str = L"Hello World";
    std::wstring subStr = L"World";
    
    size_t pos = str.find(subStr);
    
    if (pos != std::wstring::npos)
    {
        std::cout << "Substring found at position " << pos << std::endl;
    }
    else
    {
        std::cout << "Substring not found" << std::endl;
    }
    
    return 0;
}

In this example, we search for the substring "World" within the string "Hello World". The find method returns the position of the first occurrence of the substring, which is 6.

Example 2: Searching for a substring within a string starting from a specific position

#include 
#include 

int main()
{
    std::wstring str = L"I love programming in C++!";
    std::wstring subStr = L"C++";
    
    size_t pos = str.find(subStr, 10); // start searching from position 10
    
    if (pos != std::wstring::npos)
    {
        std::cout << "Substring found at position " << pos << std::endl;
    }
    else
    {
        std::cout << "Substring not found" << std::endl;
    }
    
    return 0;
}

In this example, we start searching for the substring "C++" from position 10 within the string "I love programming in C++!". The find method returns the position of the first occurrence of the substring after position 10, which is 22. The wstring find method is part of the C++ standard library and does not require any additional package or library to be installed.
