Can strcmp() work with strings in c++? -


i have line of code

if(strcmp(ob[i].getbrand(), ob[j].getbrand()) > 0)

and error

error c2664: 'strcmp' : cannot convert parameter 1 'std::string' 'const char *'

does mean strcmp doesnt work strings, instead has convert char?

don't use strcmp. use std::string::compare has same behavior strcmp.

if(ob[i].getbrand().compare(ob[j].getbrand()) > 0)

or better

if(ob[i].getbrand() > ob[j].getbrand())

generally should use std::string::compare when have test various cases strings different, e.g.

auto cmp = ob[i].getbrand().compare(ob[j].getbrand());  if(cmp == 0) ... else if(cmp > 0) ... else if(cmp < 0) ...

in way have comparison operation on strings once.

however, in case it's somehow apparent have use comparison result in single case (i'm assuming, don't know context of code given), operator > suffice, , easier on eye (the brain!).
