Today, my classmates asked me if there is any simple way to find out the sum of two numbers in C + +, then there is a way to title.The return value of LOG10 (100) is the return value of 2,log (999) is more, but if you position the return value int,

Sometimes you will also encounter Std:vector and turn std:string each other in the case of conversion.First look at vector how to turn a string:STD:: vectorchar>*data = Response->getresponsedata ();STD::stringRes//Method one for(inti =0; Isize (); ++
