Differences between C string and compare

0 votes

I just read some recommendations on using

std::string s = get_string();
std::string t = another_string();

if( !s.compare(t) ) 
{

instead of

if( s == t )
{

I nearly always choose the final one since it feels more natural and readable to me. 

I had no idea there was a separate comparison function. 

To be more specific, I assumed == would invoke comparison ().

What are the distinctions? 

In what circumstances should one approach be preferred over another?

I'm just thinking of scenarios when I need to know if one string has the same value as another.
