Inline FunctionsSummarySometimes, the time to execute a function is smallcompared to time to call itUse inline keywordinline double sqr(double x) {return x * x;}• any decent compiler will generate inline code insteadof function call if function is small• but inline keyword is only a hint to the compiler• inline functions are usually defined in header fileNow we covered enough C/C++ so that every thingyou can do in Fortran you can now do in C/C++You can also do more than you can do in FortranNext session we introduce classes and start on theroad towards object-oriented programming.• convention puts inline functions in file with .iccsuffix that is included by header fileConsequences of inline functions• program might be faster• program will be larger• might have poor instruction cache performance anddebugging might be harderBABAR C++ Course 64 Paul F.
