simple example about write() and read()

unsigned char str1[]="I Love You";
　　　　int n[5];
　　　　ifstream in("xxx.xxx");
　　　　ofstream out("yyy.yyy");
　　　　out.write(str1,strlen(str1));//put the string str1 write in yyy. yyy　file
　　　    in.read((unsigned char*)n,sizeof(n));//from xxx.xxx  read designated integer, Note: type conversion
　　　　in.close();out.close();

setOn &setOff

void setOn(unsugned int&val, int bitNo){
val = val | (1<<bitNo);
}

bol setOff(unsigned int&val, int bitNo){
val = val & ~（1<<bitNo);
}
