Cant compile and run this program: when trying to build it the following errors displayed:

1-- Error 1 error LNK2019: unresolved external symbol "void __cdecl getRainfall(double * const,class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > * const,int)" (?getRainfall@@YAXQANQAV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@H@Z) referenced in function _main rainfall.obj rainfall

It is basically saying it can't find a function called getRainfall.

have you actually written this function?


(and before you reply - I tell you now that the answer is- No you haven't)

Thanks for you helps. I realized that the problem was that I wrote that function with a lower case "r" and capital 'R" in the same code
