Hello,

I need to know how the get the integer value of a byte and vice versa.

I want to get the integer value from a byte read from a binary file.
I also want to convert the integer value back into a byte value for write.

Below I have code where the current byte is read into the variable 'byte". I am basically copying one file to the other.

Thanks.

#include <fstream.h>
#include <iomanip.h>
int main()
{
int ind, tot;
unsigned char byte;

ifstream infile("inputfile.dat", ios::in | ios::binary);
ofstream outfile("outputfile.dat", ios::binary );

for (!infile)
{
int iVal;
unsigned char ucVal;

infile.read( byte, 1 );

//this code I test with Visual C++.

//convert unsigned char to integer
iVal = (int)byte; //int cast

//convert integer value to unsigned char
ucVal = (unsigned char)iVal; //cast to unsigned char

outfile.write( byte, 1 );

return 0;
}

}
