Using Binary I/O with Array-Based Streams

 #include <iostream>#include <strstream>using namespace std;int main(){  char *p = "this is a test\1\2\3\4\5\6\7";  istrstream ins(p);  char ch;  while (!ins.eof()) {                       // read and display binary info    ins.get(ch);    cout << hex << (int) ch << ' '; }  return 0;}
