file input
Hi all,
I have problems with reading in from a file.
The first line and the first integer (variable minute) is read in correctly,
but there`s problems with the rest of the file. The file format is fixed and
cannot be altered.
The input file is as follows:
1 10 1 10 1 10 1 10 0 0 1 10
1 a 40 b 24 c 35 d 6 e 6 f 6 g 6
h 6 i 6 j 6 k 6 // a to k is stored as
name[1][0..11], and item[1][0..11]
2 A 4 B 4 C 4 D 4 E 4 F 4 G 4
H 4 I 4 J 4 K 4 L 4 N 4 O 4
P 4 Q 4 R 4 S 4 T 4 // A to T is stored as
name[2][0..19], and item[1][0..19]
3 U 1 // U is stored as name[3][0] and item[3][0]
26 V 1 // V is stored as name[4][0] and item[4][0]
// 3 newlines till the end-of-file
All the alphabets are stored as "name" and the integer behind each alphabet
is stored as "item" for the corresponding "name". Both variables "name" and
"item" are stored as 2D array, i.e. name[minute][i].
My code is as follows:
#include <iostream.h>
#include <fstream.h>
#include <ctype.h>
void readmin(int& minute, int nextmin, ifstream& infile, int i)
{
char name[30][20];
int item[30][50];
char temp;
while (nextmin == 1)
{
infile >> name[minute][i] >> item[minute][i];
i++;
if (infile.get() == `
`)
{
infile >> temp;
if (isdigit(temp)) // check if the input is another minute
{
nextmin = 0;
minute = temp; // Problem: Is there a way to change char to
int?
}
else
{
name[minute][i] = temp;
infile >> item[minute][i];
i++;
}
}
}
}
void main()
{
ifstream infile;
infile.open("ffs2.txt", ios::in);
int nextmin;
int i, minute = 0, op[6], e[6];
for (i = 0 ; i < 6 ; i++)
{
op[i] = 0;
e[i] = 0;
}
for (i = 0 ; i < 6 ; i++) // To read in the first line of 1s, 0s, and
10s
{
infile >> op[i] >> e[i];
}
infile >> minute; // read in the first minute
while (!infile.eof())
{
nextmin = 1;
i = 0;
readmin(minute, nextmin, infile, i);
}
infile.close();
}
I`m trying to call the function "readmin()" to read in the "minute", "name"
and "item" from "a 40" (in the 2nd line of input file) until the end of
file. I`m using Borland 5.0. When I run the program, it tells me "Thread
stopped.... Access Violation....".
Please tell me what`s wrong with my program.
Thank you.
Regards,
Rayne

Hi Rayne,
Could you re-post the files (especially the data file)
as mail-attachment? Yahoo doesn`t show them correctly
(I have HTML-mode turned off), so I can`t figure out
how should it be read.

file input
Hi all,
I have problems with reading in from a file.
The first line and the first integer (variable minute) is read in correctly, but there`s problems with the rest of the file. The file format is fixed and cannot be altered. I`m sending the file input and the cpp file as attachments.
All the alphabets are stored as "name" and the integer behind each alphabet is stored as "item" for the corresponding "name". Both variables "name" and "item" are stored as 2D array, i.e. name[minute][i].
From the input file,
a 40 to k 6 is stored as name[1][0..11], and item[1][0..11]A 4 to T 4 is stored as name[2][0..19], and item[1][0..19]U 1 is stored as name[3][0] and item[3][0] respectivelyV 1 is stored as name[4][0] and item[4][0] respectively
3 newlines till the end-of-file
I`m trying to call the function "readmin()" to read in the "minute", "name" and "item" from "a 40" (in the 2nd line of input file) until the end of file. I`m using Borland 5.0. When I run the program, it tells me "Thread stopped.... Access Violation....".
Please tell me what`s wrong with my program.
Thank you.

Rayne
