Error Allocating Memory

[sid78669]

Hello everyone,

I am having trouble with a part of my Assignment and think i am missing something here. I have a Field class as below:

class Field{
    char * fstr;
    int frow, fcol, len, fslen, foffset, fstart, fctype;
    bool fedt;
    static int finsert;

public:
    Field(char * str, int row, int col, int flen, int slen, int offset=0, int start=0, int ctype=1);
    void draw( ) const;
    int draw(int row, int col, int l, int h, char edge, char top_btm, char ls_rs) const;
    bool editable( ) const;
    int edit();
    char * data( ); 
    friend int console_Edit(char *, int, int, int, int, int *, int *, int *, int);
    };

And the definition of the constructor is:

Field::Field(char * str, int row, int col, int flen, int slen, int offset, int start, int ctype){
    fstr = new char[slen];
    strcpy(fstr, str);
    frow = row;
    fcol = col;
    len = flen;
    fslen = slen;
    foffset = offset;
    fstart = start;
    fctype = ctype;
    }

Now I use these Field objects in a class called TextField:

class TextField{
    Field * lines;
    int txtWidth, txtHeight, txtRow, txtCol;
    char txtEdge, txtTop_btm, txtLs_rs;
    char * txtPage;

public:
    TextField(char *page, int row, int col, int width, int height, char edge, char top_btm, char ls_rs);
    int edit();
    ~TextField();
    };

with the constructor as:

TextField::TextField(char *page, int row, int col, int width, int height, char edge='+', char top_btm='-', char ls_rs='|'){
    txtPage = new char[strlen(page)];
    strcpy(txtPage, page);
    int num = strlen(page) / width;
    lines = new Field [num];
    int done = 0;
    char * temp = new char[width];;
    for(int i = 0; i < num; i++){
        temp = getLine(txtPage, width - 2, i, done);
        lines[i] = new Field(temp, row + i, col, width, width, 0, 0, 0);
        done = strlen(temp);
        }
    txtRow = row;
    txtCol = col;
    txtWidth = width;
    txtHeight = height;
    txtEdge = edge;
    txtTop_btm = top_btm;
    txtLs_rs = ls_rs;
    }

The problem is that I dnt have a constructor for Field that accepts 0 arguments. So I created a blank constructor. Also, When in the TextField's constructor, when the value for 'i' in the for loop goes above 1, I get a memory allocation error.

Can someone please help me?? I already have 600 lines of code that is working fine when tested individually, but the constructor is screwing everything up!

In class TextField, lines needs to be a Field** And in TextField::TextField, line 5 should be lines = new Field*[num];

That works Thanks!!
