Find and replace a string in c++

This can be handy many a times when you are working on a C++ application. There is a no direct method in the standard to do the same except when you are using a boost library. Below is a simple function that I use regularly in my applications which comes in handy for me all the time

template<class T>
int inline findAndReplace(T& source, const T& find, const T& replace)
{
    int num=0;
    int fLen = find.size();
    int rLen = replace.size();
    for (int pos=0; (pos=source.find(find, pos))!=T::npos; pos+=rLen)
    {
        num++;
        source.replace(pos, fLen, replace);
    }
    return num;
}
