    Re: C++ help

    Code:
    #include<iostream>
    #include<fstream>
    #include<string>
    #include<iomanip>
    #include<cstdlib>
    #include<climits>
    
    const int MAX_ROWS = 10;
    const int MAX_COLS = 10;
    using namespace std;
    
    typedef int BitArray[MAX_ROWS][MAX_COLS];
    
    struct ResultArrays
    {
       BitArray orArray;
       BitArray andArray;
       BitArray xorArray;
       int rows;
       int cols;
    };
    
    struct AllArrays
    {
       ResultArrays resultarrays;
    };
    
    void OpenInputFile(ifstream&);
    bool ReadInputFile(int arg[], ifstream&);
    //void calculateOrArray();
    //void calculateXOrArray();
    //void calculateANDArray();
    //void ArrayInt1(IntArray);
    //void PrintArrays(IntArray, int[][COLS]);
    
    int main()
    {
    
       ifstream inFile;
       
       AllArrays info;
       
       OpenInputFile(inFile);
       
        if (inFile.fail() && !inFile.eof())
        {
            string infilename;
            
            cout<<" \nProcessing information. Please wait...."<<endl;
            cout << endl << string(15,'*') << "File Read Error"<<string(15,'*')<<endl;
            cout << "==> An error has occured while reading\n";
            cout << "==> the input file. Error in file content\n " << infilename <<endl;
            cout << "==> Terminating program!!!"<<endl;
            cout << string(47, '*')<< endl<<endl;
            
            inFile.clear();
        }
      
       return 0;
    }
    void OpenInputFile(ifstream& inFile)
    {
        string infilename;
       
        cout<<endl;
        cout << " Enter name of input file:";
        cin >> infilename;
        cin.ignore(INT_MAX,'\n');
        cout << infilename << endl;
        inFile.open(infilename.c_str());
        
        while (inFile.fail())
        {
            cout << endl << string(15,'*') << "File Open Error"<<string(15,'*')<<endl;
            cout << "==> Input file failed to open properly!!\n";
            cout << "==> Attempted to open file: " << infilename <<endl;
            cout << "==> Please try again...\n";
            cout << string(47, '*')<< endl<<endl;
            
            inFile.clear();
            cout << " Enter name of input file:";
            cin >> infilename;
            cin.ignore(INT_MAX,'\n');
            cout << infilename << endl;
            inFile.open(infilename.c_str());
            
        }
        
    }
       
    bool ReadInputFile(AllArays[]& info,ifstream& inFile)
    {
          getline(inFile, info.resultarrays.orArray,'\n'); 
          
          return bool(inFile);
    }
    this is what i have so far. I am already throwing a error.

    Re: C++ help

    When posting code, please use code tags so that the code is readable. Go Advanced, select the formatted code and click '#'.

    Code:
    AllArays[]& info
    By default, an array is effectively passed as a pointer so you don't need the & ref.

    Code:
    AllArays info[]
    But you are not accessing info as an array - you are accessing as a struct. So do you mean

    Code:
    AllArays& info
    Also note that the function declarations need to match the function definition

    Code:
    bool ReadInputFile(int arg[], ifstream&);
    ...
    bool ReadInputFile(AllArays[]& info,ifstream& inFile)
    These need to be the same.
