C++ Programming :: Mixing default and non-default parameters in Constructor?


	Mixing default and non-default parameters in Constructor? Are there some way to mix default and non-default parameters in a constructor: class test { public: test(int i = 45, int j) : pp(j){} private: int pp; int i; }; The above does not work and gives the error: main.cpp:144: error: default argument missing for parameter 2 of test::test(int, int) make: * [main.o] Error 1 - Hide quoted text - desktop wrote: > Are there some way to mix default and non-default parameters in a > constructor: > class test { > public: > test(int i = 45, int j) : pp(j){} > private: > int pp; > int i; > }; > The above does not work and gives the error: > main.cpp:144: error: default argument missing for parameter 2 of > test::test(int, int) > make: * [main.o] Error 1 Yes, but default arguments have to be the last one[s].

Note also, that you did not initialize your member variable "i".
