Reading the running process from OS and displaying it through C++!

jamilkhan7272 (2)
This code will read the running process from OS and display it (C++). Specifically, the OS here is Windows XP. The Problem(error) is in (i think) prototype. By the way, it displays following errors.

Error 1 : error LNK2019: unresolved external symbol _EnumProcesses@12 referenced in function _main

Error 2 : error LNK2019: unresolved external symbol _GetModuleBaseNameA@16 referenced in function "void __cdecl DisplayProcessNameAndID(unsigned long)" (?DisplayProcessNameAndID@@YAXK@Z)

Error 3 : error LNK2019: unresolved external symbol _EnumProcessModules@16 referenced in function "void __cdecl DisplayProcessNameAndID(unsigned long)" (?DisplayProcessNameAndID@@YAXK@Z)

Error 4 : fatal error LNK1120: 3 unresolved externals C:\Documents and Settings\Windows\My Documents\Visual Studio 2008\Projects\a\Debug\a.exe
