I want to check szDir in szSelectedDir . I want the function to consider the below inputs are different. My sample function is not handling the scenario, please let me know the good solutions.

string szSelectedDir ="C:\\Windows1\Test";
string szDir="C:\\Windows";

void IsWindowsDirectory(const string szSpecialPath, const string szSelectedPath)
{

    if(szSelectedPath.compare(szSpecialPath) == 0)
    {
        printf("Both paths are same ");

    }
    else if(szSelectedPath.find(szSpecialPath) != string::npos)
    {
        printf("Both paths are same ");
    }
    else
    {
        printf("Both paths are different ");

    }

To check szDir in szSelectedDir .

if (szSelectedDir.find(szDir) != string::npos)
{
    // You found szDir in szSelectedDir
}

As someone already said, comparing strings in C++ is pretty straightforward...

if (szSelectedPath == szSpecialPath)

I suggest you to pass strings by reference (strings not null, amongst other things).
