Passing objects in functions

roovraven (11)
When I try to pass an object containing a pointer as member variable in a function within main compiler gives me this warning

obj\Debug\main.o||In function `main':|
D:\programmic++\bigstuff\main.cpp|23|undefined reference to `setValues(std::string, largeIntegers&)'|
D:\programmic++\bigstuff\main.cpp|29|undefined reference to `setValues(std::string, largeIntegers&)'|
||=== Build finished: 2 errors, 0 warnings ===|

Here's my code for main

You declared: void setValues(string, largeIntegers&); , but defined: void setValues(string Linenum, largeIntegers numint).

Note lack of "&" in the line 40. It should be void setValues(string Linenum, largeIntegers & numint)
