Solution :

For single character it is easier to use the std::replace algorithm:

std::replace(passCode.begin(), passCode.end(), ' ', '_');

If you can not use the algo header you can use your own replace function. 

It can be done with a simple loop:

template<typename Iterator, typename T>
void replace(Iterator begin, Iterator end, const T& old_val, const T& new_val)
{
    for (; begin != end; ++begin)
        if (*begin == old_val) *begin = new_val;
}
I followed above approch and my issue got ressolved.
