Ich versuche, mein finales Debugging heute Abend zu beenden. Mein Problem ist, dass ich diesen Code für ein paar Tage geschrieben habe und es ein paar Probleme hat. Previous PostArrays und Suche nach ihnen
Es kompiliert jetzt und stürzt nicht ab, aber es gibt einige Probleme mit meinen Funktionen, die nicht richtig funktionieren (oder überhaupt).
#include <iostream>
#include <string>
#include <fstream>
using namespace std;
string bookTitle [50];
string bookAuthor [50];
int loadData (string pathname);
int showall (int counter);
int authorSearch (string bookAuthor [50]);
int main()
{
string pathname;
int counter=0;
char choice;
cout<<"Input the name of the file to be accessed: ";
cin>>pathname;
loadData (pathname);
showall (counter);
cout<<"\n\n\n\n What would you like to do \n (A for Author Search , T for Title Search, Q to quit):";
cin>>choice;
while (choice != 'Q' , choice != 'q')
{
if (choice == 'A', choice == 'a')
{
int authorSearch (string bookAuthor [50], char choice);
}
if (choice == 'T', choice == 't')
{
int titleSearch (string bookTitle [50], char choice);
}
}
cout<<"Press <Enter> to Exit";
cin.ignore();
cin.get();
return 0;
cout<<"Press <Enter> to Exit";
cin.ignore();
cin.get();
return 0;
}
int loadData (string pathname) // Loads data from infile into arrays
{
fstream infile;
int counter = 0;
infile.open(pathname.c_str()); //Opens file from user input in main
if(infile.fail())
{
cout << "File failed to open";
return 0;
}
while (!infile.eof())
{
infile >> bookTitle [counter] ; //takes input and puts into parallel arrays
infile >> bookAuthor [counter];
counter++;
}
infile.close();
}
int showall (int counter) // shows input in title(author) format
{
cout<<bookTitle<<"("<<bookAuthor<<")";
}
void authorSearch (string bookAuthor [50], char choice) // Function to search Author Array
{
string target = "";
cout<<"Which author would you like to search for: "<<target; //input
for (int count = 0; count++;)
{
if(bookAuthor[count] == target) //tests input against array and outputs result
{
cout<<bookTitle[count]<<bookAuthor[count];
}
}
}
void titleSearch (string bookTitle [50], char choice) // Function to Serch Title Array
{
string target = "";
cout<<"Which author would you like to search for: "<<target; //input
for (int count = 0; count++;)
{
if(bookAuthor[count] == target) //tests input against array and outputs result
{
cout<<bookTitle[count]<<bookAuthor[count];
}
}
}
Neueste Version, keine wesentlichen Verbesserungen. Ich habe Probleme, die Funktionen nach der Menüauswahl zu funktionieren. ShowAll scheint zu funktionieren, gibt aber hex aus. Danke nochmal allen!

Sie möchten vielleicht expliziter mit Ihrem Komma-Operator sein. Verwenden Sie && oder || stattdessen. – collinjsimpson
Bitte markieren Sie dies als Hausaufgabe, ich weiß, dass Sie vorherige Post erwähnt, aber dies tut nicht. Auch ein Hinweis: Wenn Sie die falsche Auswahl auswählen, wie kann ich wieder wählen? –
