writing binary file in c++ is producing ascii output

This might be a very silly bug, but I am very confused to why my code is writing the specified data as ascii characters in the file and not in binary format? What am I missing? Most tutorials I read online followed this setup so I have to be missing something crucial. Any help is appreciated. Also the output in the file is "123456"

void MipsInterpret::outFile() {
std::cout << "Writing file" << std::endl;
std::ofstream myFile;
myFile.open(outputFile, std::ios::binary);
if (!myFile) {
    std::cerr << outputFile << " failed to open. Closing " << std::endl;
    exit(1);
}
std::string test = "add $1, $2, $3";

char list[6] = {'1', '2', '3', '4', '5','6'};

myFile.write(list, 6);

if (!myFile.good()) {
    std::cerr << "Error occurred at writing time!" << std::endl;
    exit(1);
}
myFile.close();

}

Insted of

char list[6] = {'1', '2', '3', '4', '5','6'};

do

char list[6] = {1, 2, 3, 4, 5, 6};

That will fix the issue because '1' is actually 49 in binary
