How to Use

const int MAX = 100000;

progress_display show_progress(MAX);

for(int i=0; i<MAX; i++) {DoSomething(i);++show_progress;

}

const int MAX = 100000;

progress_display show_progress(MAX);

for(int i=0; i<MAX; i++) {DoSomething(i);++show_progress;

}

Beautiful Interface!

const int MAX = 0;

progress_display show_progress(MAX);

cout << show_progress.expected_count();

const int MAX = 0;

progress_display show_progress(MAX);

cout << show_progress.expected_count();

progress_display(

unsigned long expected_count,

const std::string & s1 = "¥n",

for(int i=0; i<MAX+MAX; i++) {DoSomething(i);++show_progress;

}

const int MAX = 100000;

progress_display show_progress(MAX);

for(int i=0; i<MAX+MAX; i++) {DoSomething(i);++show_progress;

}

const int MAX = 100000;

progress_display show_progress(MAX);

for(int i=0; i<MAX+MAX; i++) {DoSomething(i);++show_progress;

}

const int MAX = 100000;

progress_display show_progress(MAX);

for(int i=0; i<MAX*MAX; i++) {DoSomething(i);++show_progress;

}
