Example:

#include <fstream>

int main()
{
std::ofstream logfile("filename");
return 0;
}

Example:

#include <fstream>

int main()
{
struct
{
char array[10][10];
} data = {0};

std::ifstream external("filename");

if(external)
external.read(reinterpret_cast<char *>(data.array),
sizeof data.array);

return 0;
}
