编译时加上 -lncurses选项

#include <unistd.h>
#include <stdlib.h>
#include <stdio.h>
#include <curses.h>

int main()

exit(1);
}
if(start_color() != OK)

fprintf(stderr,"error - could not initialize colors\n");
exit(2);

}
clear();
mvprintw(5,5,"there are %d colors,and %d color_pairs available",COLORS,COLOR_PAIRS);
refresh();

init_pair(1,COLOR_RED,COLOR_BLACK);
