Function Fun Mysterious Error
Nov 11, 2014 at 7:04am UTC
Hey all so I'm writing a program demonstrating function calling in main. I tried building it but I got an error message I cannot decipher. here it is:
1>Function_Fun.obj : error LNK2019: unresolved external symbol "int __cdecl getInteger(int,int)" (?getInteger@@YAHHH@Z) referenced in function _main
1>C: : fatal error LNK1120: 1 unresolved externals
Any ideas what I'm doing wrong here?

You repeated almost the same error again haha
1 2 3 4
int getInteger(int Height,int Width);//your prototype declaration line 7
Height = getInteger(3, 10);/// you called this function in line 19 and 21
/// prblm is your above function isn't defined any where
int getInteger (int Height); //line 31 doesn't match your function calls in main
/// you can redefine your function to take an extra arg or simply overload it
