Thread: Help me create a binary file read routine using C or C++

Hi everyone
Please bear with this beginner in C/C++ question....

Problem:
I need to develop simple program for canny edge detector.
Now, I need help to create a routine to read a binary file. The routine must be able to read a binary file and pass these values:
a) first 2 bytes as unsigned integer (assign it to "row" variable)
b)next 2 bytes as unsigned integer (assign it "col" variable)
skip 6 bytes
e) a 2 dimensional array ( data[row][colum] ) from the subsquent bytes left, 1 byte makes up 1 element.
You can use fread or fstream for this routine.

ex: using hexview, the input file is:
02 00 02 00 FF 01 02 01 00 01 11 FF 22 44
then the program
should return
row = 2 (from 00 02-1st 2 bytes)
col = 2 (from (00 02 - 1st 2 bytes)
skip the next 6 bytes (FF 01 02 01 00 01)
data[row][column]= {(17,255)(34,68)} (the rest bytes)

My current program as follow

Code:

#include <stdio.h>
#include <iostream>
void infile(char i){
FILE* input = fopen(i, "rb");
int col, row;
double data[600][600];
fclose(input);
}
int main(){
char i_f;
printf("Please enter input image file name");
cin >> i_f;
infile (i_f);
}

I also have the problem to pass the file input from the main program to the routines with above codes. Seems the parameter for char i mismatch or something.
Could anyone help me to solve this?

Thx for the help.

Err, pardon me for the lack in indentation, I posted it in a hurry.

Yep, I do realize that using fopen or fclose is not proper for C++, instead fstream is preferable.
Actually I did do some search from the net before posting the question to this forum. I've look at examples provided. But, I'm still clueless as all of the examples I find are not so specific.

I'll really appreciate if you could instead provide me with the solution or maybe pointer to sites that give specific examples. Before the flaming starts, I do realize that solution given directly is a bad practice as spoon feeding, but for my case as I'll need to expand the code more and more later on to practice the canny detector, I believe spoon feeding case is irrelevant. Not to mention, most of the programmers considered this as basic and not so hard to do....
