HI everyone, First I want to thanks all the help in here to solve my previous problem:)! It mains a lot to me!;)
Now, I would like to use the preivous program to build a static library and try to test it.
When I finish build the library and apply it for test, there are run times error occured:
1>fortest.obj : error LNK2019: unresolved external symbol "public: void __thiscall login::find(void)" (?find@login@@QAEXXZ) referenced in function _main
There are four of them and I know they are the same things.
I do not know how to fix them....:(
The code:
The header file is :
#include <fstream>
#include <string>
class login
{
public:
void setuser();
void write();
void read();
void find();
private:
char inputusername[99];
};
The code file is :
void find()
{
ifstream file;
file.open("file.txt");
string input=inputusername;
string input_line;
bool found = false;
while( file >> input_line ) {
