You forgot to include the parameter list in your forward declaration for "copysearch()", so now the linker doesn't know where to look for it.
error LNK2019: unresolved external symbol "int __cdecl copysearch(void)" |
Your function definition doesn't agree with the prototype in terms of parameters.
function prototype takes no parameters
int copysearch();
function call sends no parameters
num = copysearch();
but function definition expects a parameter
int copysearch(int copyarrray[])

The error says it can't find an implementation of line 10.
