Thread: Need Help with 2D array (Library System)

Hey Guys, I need assistance with my code because everytime it skips the part to input. Maybe someone could help me with my code. here it is.

Code:

int main()
{
    int index,choice,choiceloop,row=0,col=0,main=0,stop;
    char bookstore[20][50],loopchoice,booktitle[50];
    do
    {
    system("cls");
    cout<<"Welcome to MMSU's Library System"<<endl;
    cout<<"Press 1 to Add Books"<<endl;
    cout<<"Press 2 to Display Books"<<endl;
    cout<<"Press 3 to Search Books"<<endl;
    cout<<"Press 4 to Edit Books"<<endl;
    cout<<"Press 0 to exit the System"<<endl;
    cout<<endl<<"Choice: ";
    cin>>choice;
    if(choice==1)
    {
        system("cls");
        cout<<"ADDING BOOK - MMSU Library System"<<endl;
        row=0;
        do
        {
            cout<<endl<<"Title: ";
            fgets(bookstore[row],50,stdin);
            //for(row=0;row<20;row++)
            //    for(col=0;col<50;col++)
            //        booktitle[col]=bookstore[row][col];
            cout<<endl<<"Do you want to enter again(Y/N): ";
            cin>>loopchoice;
            if(loopchoice=='y'||loopchoice=='Y')
            {
                choiceloop=1;
                row++;
            }    
            else if(loopchoice=='n'||loopchoice=='N')
            {
                choiceloop=0;
                main=1;
            }    
        }
        while(choiceloop==1);

I know its a long read but I'd be grateful if you could help. Thanks in Advance Guys

Thanks sir Laserlight, I have already made that work using cin.getline. Now i have a new problem.

Code:

else if(choice==3)
    {
        system("cls");
        cout<<"SEARCH BOOK - MMSU Library System"<<endl;
        do
        {
            cin.ignore();
            cout<<endl<<"Find Book Title: ";
            cin.getline(booktitle,50);
            for(row=0;row<20;row++)
            {
                for(col=0;col<50;col++)
                {
                    if(booktitle[col]==bookstore[row][col])
                        continue;
                        
                    else if(booktitle[col]!=bookstore[row][col])
                    {
                        stop=1;
                        cout<<"No Book Found";
                        break;
                    }
                }
                if(stop=1)
                    break;
            }    
            cout<<endl<<"Do you want to borrow book/s again(Y/N): "<<endl;
            cin>>loopchoice;
            if(loopchoice=='y'||loopchoice=='Y')
                choiceloop=1;
            else if(loopchoice=='n'||loopchoice=='N')
            {
                choiceloop=0;
                main=1;
            }
        }
        while(choiceloop==1);

In this code the program has to search for the book in the array.

For Example:
I chose 1 to add book Title: How I Met Your Mother/how i met your mother (How do I configure it to check for both lower case and upper case?)

then I chose 3 to search Book Title.
I enter title: How I Met Your Mother
but it returns No Book Found.

I have already gone past the 2nd problem, Just used toupper now I have a third problem and hopefully the last one.

Code:

else if(choice==2)
    {
        system("cls");
        cout<<"DISPLAY BOOK - MMSU Library System"<<endl;
        cout<<"\tBook Index\t\tTitle"<<endl;
        for(row=0;row<20;row++)
            cout<<"\t"<<row<<"\t\t"<<bookstore[row]<<endl;
        main=1;
        system("pause");
    }

The problem is that the program only has to display the row with values in it. my program displays 0-19 with trash values. how do I do it?

Done! That was the last problem. Thank you sir laserlight! you are a very helpful person. Thank you so much!
