I'm getting a linker error?
Error 1 error LNK2019: unresolved external symbol "public: __thiscall Fraction::Fraction(int,int)" (??0Fraction@@QAE@HH@Z) referenced in function "public: class Fraction __thiscall Fraction::Add(class Fraction,class Fraction)" (?Add@Fraction@@QAE?AV1@V1@0@Z) C:\Users\Jesse\Desktop\C++ II\Chapter_15_Exercise_1\Chapter_15_Exercise_1\Cha pter_15_Exercise_1.obj Chapter_15_Exercise_1
Any idea how to fix this? I can't figure out for the life of me how to fix it?
