I have problem completing a program and I would be really really thankful if someone could help me with this .
This is my code so far:
#include <fstream>
#include <iostream>
#include <conio.h>
using namespace std;
void registret(void);
void lista1(void);
void lista2(void);
void search(void);
void sortering(void);
void addcar(void);
void sell(void);
struct bil
{
char modell[30];
char color[15];
int saleprice;
int retailprice;
int sold;
int instock;
};
int main()
{
lista1();
return 0;
}
void registret(void)
{
char vekt[50][99];
ifstream lasa("bilreg.txt");
int antal=0;
while( lasa.getline(vekt[antal], 99))
{
antal++;
}
for( int i=0;i<antal;i++)
cout<<vekt[i]<<endl;
cout<<endl;
_getch();
}
void lista1(void)
{
int val;
cout<<"0. Avsluta "<<endl;
cout<<"1. Se registret "<<endl;
cout<<"2. S\x94ka/Sortera "<<endl;
cout<<"3. S\x84lj"<<endl;
cout<<"4. L\x84gg till ny bilmodell"<<endl;
cout<<"Ange ditt val: ";
cin>>val;
cout<<endl;
switch(val)
{
case (0): cout<<"Programmet avslutas!"<<endl;
break;
case (1): registret();
break;
case (2): lista2();
break;
case (3): sell();
break;
case (4): addcar();
break;
default: cout<<"Valet finns ej"<<endl;
}
}
void lista2(void)
{
int val2;
cout<<"21. S\x94ka"<<endl;
cout<<"22. Sortera"<<endl;
cout<<"23. Se registret"<<endl;
cout<<"24. \x86ter till huvudmenyn"<<endl;
cout<<"Ange ditt val: ";
cin>>val2;
cout<<endl;
switch(val2)
{
case (21): search();
break;
case (22): sortering();
break;
case (23): registret();
break;
case (24): lista1();
break;
default: cout<<"Valet finns ej"<<endl;
_getch();
}
}
void search(void)
{
cin.ignore();
char vekt[30];
char namn[30];
bool ok=false;
cout <<"Ange en modell: ";
cin.getline(namn,30);
ifstream lasa("bilreg.txt");
if (! lasa)
{
cout<<"kunde inte hitta filen:";
}
while( lasa.getline(vekt, 30))
{
if (strcmp (vekt,namn) == 0)
{
ok=true;
break;
}
}
if (ok)
cout<<"Modellen finns i registret!"<<endl;
else
cout<<"Modellen finns inte med i registret!"<<endl;
lasa.close();
}
void sortering()
{
}
void addcar(void)
{
cin.ignore();
bil reg;
ofstream utskrift("bilreg.txt", ios::app);
if(!utskrift)
{
cout<<"Filen kunde inte hittas"<<endl;
}
for(int i=0;i<1;i++)
{
cout<<"Ange modell:" ;
cin.getline(reg.modell,30);
cout<<"Ange f\x84rg: ";
cin.getline(reg.color,15);
cout<<"Ange antal i lager :";
cin>> reg.instock;
cout<<"Ange antal s\x86lda: ";
cin>>reg.sold;
cout<<"Ange s\x84ljpris: ";
cin>> reg.saleprice;
cout<<"Ange ink\x94pspris: ";
cin>> reg.retailprice;
cin.get();
cout<<endl;
utskrift<< reg.modell <<" ";
utskrift<< reg.color <<" ";
utskrift<< reg.instock<<" ";
utskrift<< reg.sold<<" ";
utskrift<< reg.saleprice<<" ";
utskrift<< reg.retailprice<<endl;
utskrift<<endl;
}
utskrift.close();
}
void sell(void)
{
}Im stuck at
void sortering()
{
}Im supposted to make a function where the program sort the list in bilreg.txt
that at the moment looks something like this:
Honda White 2 4 300000 200000
Cleo Black 1 7 1000000 900000
Ferrari Red 3 5 1200000 1000000
and it should sort it alphabetically, like this:
Cleo Black 1 7 1000000 900000
Ferrari Red 3 5 1200000 1000000
Honda White 2 4 300000 200000
Im also stuck at
void sell(void)
{
}Where you should be able to sell the cars in the bilreg.txt register
and when you do, the register should change so that the instock line gets -1 and the sold line gets +1
Please can someone help me with this?
