Hi to all?
For the past couples of weeks I have been programming to make a
program that reads a binary file and produces the equivalent text
file.
The idea is that each byte in the file represents a temperature that
can only go from 0 to 255. So I start by reading the file in to a
character array, and the do an int casting to obtain the value of each
file, so my code is something like this:
ifstream inFile("binary.dat");
ofstream outFile("binary.txt");
inFile.seekg(0, ios::end);
int size = inFile.tellg();
inFile.seekg(0, ios::beg);
char charArray[size];
inFile.read(charArray, size);
for(int= 0; i<size; i++)
{
outFile << (int)charArray[i] <<endl;
}
.... etc ...
I expected the output to range from 0 to 255, but I get values from
-128 to 127!!? and if I use (unsigned int) instead of (int) the output
is even worst.
Is there a better way to see what is the integer equivalent that each
byte holds ?
Regards,
Alexis
