You are getting wrong the function prototypes with parameters. see http://www.cplusplus.com/doc/tutorial/functions/

after i edit my source code up and down, it still come with these errors:

1 - error LNK2019: unresolved external symbol " char__cdecl search_birth(char)"(?search_birth@@YADD@Z) referenced in function main
2 - fatal error LNK1120: 1 unresolved externals

can someone guide me how to solve these problems??
