Thread: C Scrolling

I'm suppose to make a prog that displays a bunch of stuff in table form, but the amount of colums is larger than the width of the screen, how do I put in a scroll bar or something like that so I can move left and right? (A vertical one might be nice too ) All of the table data is generated by a loop too btw, with the tables "headings" outside the loop and some info at the bottom.

Well I just started coding, so I guess it for a console thingy or Dos\Windows.

Did I mention that I only started Comp Sci a couple weeks ago? I don't get most of how to even start to do what you're taking about. Maybe posting the code might help make it easier.

Code:

#include <stdio.h>
#include <conio.h>
void main () {
	FILE *indata=fopen("c:\\cs10e\\input3.txt", "r");
	FILE *outdata=fopen("C:\\cs10e\\output3.txt", "w");
	
	int lines=0, prt_num, prc_brk_quant, quant_sold, peakprt=9999, peaksale=0;
	float init_amt, unit_prc, brk_discount, grand_discount, post_brk_discount, net_pay, total_discount;
	
	clrscr();
	if (indata==NULL) {
		printf ("No data file found!");
		getch();
		exit();
		          }
	fscanf (indata,"%d", &prt_num);
	printf ("===============================================================================\n");
	printf ("Part_No. Unit_Price Price_Break_Quant Quant_Sold Initial_Amt Discount   Net_Pay\n");
	printf ("===============================================================================\n");
	fprintf (outdata,"===============================================================================\n");
	fprintf (outdata,"Part_No. Unit_Price Price_Break_Quant Quant_Sold Initial_Amt Discount   Net_Pay\n");
	fprintf (outdata,"===============================================================================\n");
	while (prt_num!=9999) {
			fscanf (indata,"%f", &unit_prc);
			fscanf (indata,"%d", &prc_brk_quant);
			fscanf (indata,"%d", &quant_sold);
		
			if (quant_sold>peaksale) {
				peakprt=prt_num;
				peaksale=quant_sold;}
			init_amt=unit_prc*quant_sold;
			
			if (quant_sold>=prc_brk_quant) {
				brk_discount=0.1*init_amt;
				post_brk_discount=init_amt-brk_discount; }
			else {
				brk_discount=0.00;
				post_brk_discount=init_amt-brk_discount; }

			if (post_brk_discount>1000.00) {
				grand_discount=.05*post_brk_discount;
				net_pay=post_brk_discount-grand_discount;}
			else {
				grand_discount=0.00;
				net_pay=post_brk_discount-grand_discount;}
		
		total_discount=brk_discount+grand_discount;
		fprintf (outdata,"%7d %11.2f %17d %10d %9.2f %9.2f %10.2f\n",prt_num, unit_prc, prc_brk_quant, quant_sold, init_amt, total_discount, net_pay );
		printf ("%7d %11.2f %17d %10d %9.2f %9.2f %10.2f\n",prt_num, unit_prc, prc_brk_quant, quant_sold, init_amt, total_discount, net_pay );
		lines++;
		fscanf (indata,"%d", &prt_num);	}
	printf ("-------------------------------------------------------------------------------\n\n");
	printf ("Total number of data lines = %d\n", lines);
	printf ("The highest quantity sold is Part No. %d, with %d sells\n", peakprt, peaksale);
	fprintf (outdata,"-------------------------------------------------------------------------------\n\n");
	fprintf (outdata,"Total number of data lines = %d\n", lines);
	fprintf (outdata,"The highest quantity sold is Part No. %d, with %d sells\n", peakprt, peaksale);
	fclose(indata);
	fclose(outdata);
	}

It's suppose to read some data (4 numbers) from a file for each "part" and list them and do some basic calculations, but I think I might have to add another column and there isn't space on the screen.
The data is suppose to be four numbers and stop reading when there is a fake part no. called 9999
Example data file>>

45 78 54 65
1 2 3 6
9999

anyone?
