Hello, I have a relly serious problem.
I'm trying to read my txt file
Tr1 6 1.5 -5.5 5 -1.4 8.5 -5.2
Aps3 3 5.5 -5.5 10
Kt4 8 -3.5 -0.5 -3.5 5.4 2.4 5.4 2.4 -0.5

void Read(FiguresCon & fgk, const char CD[CMaxx], int & n){
	double x, y, s;
	string name;
	string appav, trpav, ktpav;
	Figura f;
	ifstream fd(CD);
	
	while(!fd.eof()){
		fd >> name >> n;
		f.Check(n);/////////////////////////////PROBLEM/////
		f.SetName(name);
		f.SetN(n);
		if(n==3){
			fd >> x >> y >> s;
			f.SetAps(0, x, y, s);
			
		}else
		for(int i=0; i<n/2; i++){
			fd >> x >> y;
			f.SetKord(i, x, y);
		}
		
			fgk.Set(f);	
	}
	fd.close();
}

And here is my Figure.h file

#include <string>
using namespace std;
#pragma once
class Figure{
public:
	static const int CMax = 100;
private:
	string name;
	double xkoordinate[CMax];
	double ykoordinate[CMax];
	double spindulys;
	int n; 
public:
	// konstruktorius
	Figura(): pavadinimas(""), n(0){}
	Figura(string pavadinimas, int n):
		pavadinimas(pavadinimas), spindulys(spindulys), n(n) {}
	Figura(string pavadinimas, double spindulys, int n):
		pavadinimas(pavadinimas), spindulys(0.0), n(0){}
	//
	void SetPav(string pa) {pavadinimas = pa;}
	void SetN(int nn) { n = nn;} // negalima rasyti n=n!, nes kompiliatorius nezino kam priskirti
	void SetAp(int i, double x, double y, double s) {xkoordinate[i] = x; ykoordinate[i] = y; spindulys = s;}
	void SetKord(int i, double x, double y) {xkoordinate[i] = x; ykoordinate[i] = y;}

	string Print();
	string Check(int n);
};

and here's my Figure.cpp

string Check (int n) {
	string pavadinimasfig;
        if(n==6){
			pavadinimasfig = " Trikampis";
			return pavadinimasfig;
		}else if(n == 8){
			pavadinimasfig = " Keturkampis";
           return pavadinimasfig;
		}else if(n==3){
			pavadinimasfig = "Apskritimas";
		}else
			pavadinimasfig = "Nezinoma figura";
        return pavadinimasfig;
}

And my program doesnw work and I get this error
error LNK2019: unresolved external symbol "public: class std::basic_string<char,struct std::char_traits<char>,class std::allocator<char> > __thiscall Figura::Tikrinimas(int)" (?Tikrinimas@Figura@@QAE?AV?$basic_string@DU?$char_traits@D@std@@V?$allocator@D@2@@std@@H@Z) referenced in function "void __cdecl Ivesti(class FiguruKoteineris &,char const * const,int &)" (?Ivesti@@YAXAAVFiguruKoteineris@@QBDAAH@Z)

What is wrong?

you're reading into an int variable, but the values are not. Use float or double instead

No I'm reading n(6, 3, 8) into int variable. :( An thats correct something wrong with string Check :( Or something is wrong with calling that function and I can't find the mistake

but the linker error occurs in Ivesti. It says that Tikrinimas is not implemented
deividas717 (83)
Sorry, I dont understand. What,s wrong I dont understand wher's the mistake How I need to refer to Tikrinimas or Check function in my Read function then?
coder777 (8444)
ok let me guess:

Tikrinimas is Check
and
Ivesti is Read

Why are the errors different from your code?

Anyway

string Check (int n) {
has to be
string Figure::Check (int n) {

now is it Figure or Figura? You should stick to one

coder777, big thanks!
