Thread: Need to read hex values out of a file

i am making a program that extracts certain hex values out of a file and saves in another file.

but i have a problem, i don't know how to read hex values out of a file. i know how to read a regular text file but not hexidecimal. i need to place the file content in a variable and then separate the variable by offsets.

thanks in advance for any help
sorry if i sound stupid

Try something like this

Code:

#include <string>
#include <iostream>
#include <iomanip>
#include <sstream>

using namespace std;

int main() {
    char buffer [] ="0x1234 0x345";
    stringstream sstr( buffer );
    int word;
    sstr >> hex;
    while( sstr >> word ) {
        cout << word << " ";
    }
}

You could use a filestream instead of the stringstream

i really don't understand how that would work, where do i load the file? i just need to store the hex in a var from a file

Code:

#include <string>
#include <iostream>
#include <iomanip>
#include <fstream>

using namespace std;

int main() {
    ifstream fstr( "somefile.txt" );
    int word;
    fstr >> hex;
    while( fstr >> word ) {
        cout << word << " ";
    }
}
