Read ints from a binary file that has 2560 numbers in it and write it to a file
Code:
#include <stdio.h>
#include <iostream>
using namespace std;
// An unsigned char can store 1 Bytes (8bits) of data (0-255)
typedef unsigned char BYTE;
// Get the size of a file
long getFileSize(FILE *file)
{
long lCurPos, lEndPos;
lCurPos = ftell(file);
fseek(file, 0, 2);
lEndPos = ftell(file);
fseek(file, lCurPos, 0);
return lEndPos;
}
int main()
{
const char *filePath = "/Users/Sarang/Documents/University/Research/aCorn/NIST/Vdg0028.set";
BYTE *fileBuf; // Pointer to our buffered data
FILE *file = NULL; // File pointer
// Open the file in binary mode using the "rb" format string
// This also checks if the file exists and/or can be opened for reading correctly
if ((file = fopen("Vdg0028.set", "rb")) == NULL)
cout << "Could not open specified file" << endl;
else
cout << "File opened successfully" << endl;
// Get the size of the file in bytes
long fileSize = getFileSize(file);
// Allocate space in the buffer for the whole file
fileBuf = new BYTE[fileSize];
// Read the file in to the buffer
fread(fileBuf, fileSize, 1, file);
// Now that we have the entire file buffered, we can take a look at some binary infomation
// Lets take a look in hexadecimal
for (int i = 0; i < 2561; i++)
printf("%X ", fileBuf[i]);
cin.get();
delete[]fileBuf;
fclose(file);
return 0;
}
So this is the code, however i'm still getting some hex values in the output. What am I doing wrong ? also how can i write these values to a text file. All help is appreciated. Thanks
