can anyone help please

i want to alter the program below to the following a & b.



a. Write a program by amending the program B2 above, so that as well as being able to
book a particular hour in the day, the user can request the first free hour of the day.

b. Write a program by amending the program B2 above (this is a bit more tricky), so that the
user can make an appointment of more than one hour in length. The user enters a start hour
(e.g. 10 ) and required length in hours (e.g. 2). The program checks to see if the whole
period is free and if it is it makes the booking, otherwise it rejects it.

====================
the program
====================

#include <iostream>

class Day{
private:
int day,month,year;//Date
bool schedule[9];//Hours 9am-6pm
public:
Day(int,int,int);//Constructor
~Day();//Destructor
void setTime(int);
bool checkTime(int);
void display();
};

Day:ay(int d,int m,int y){//Pass date to constructor
day=d;month=m;year=y;//Set the date
for(int i=0;i<9;++i)schedule=false;//Initialise all the hours in the day to “free”
}

Day::~Day(){}

bool Day::checkTime(int t){
if(t>5&&t<9)return 0;//Invalid time
else t+=(t>=9?-9:3);

if(!schedule[t]){//Check if booked
schedule[t]=true;//Now booked
return 1;//Success!
}
else return 0;//Not available...
}

void Day::display(){
std::cout<<day<<'/'<<month<<'/'<<year<<std::endl;//Display day
for(int i=0;i<9;++i)std::cout<<(i<4?i+9:i-3)<<(i<3?"am":"pm")<<'\t'<<(schedule?"Booked":"Available")<<std::endl;
}

int main(){
int d,m,y,t;
std::cout<<"Input the date:\n";
std::cin>>d>>m>>y;
Day MyDay(d,m,y);//Create a day

do{
std::cout<<"Input appointment time:\n";
std::cin>>t;
}while(!MyDay.checkTime(t));//Do until you find a free time

MyDay.display();

return 0;
}

That sounds a lot like you asking us to make your homework assignment. Ask a specific question, show that you tried and got stuck, or this tread is likely to be reported and deleted, as it is against the forums policies.

1. Please use [code][/code] tags when posting code.

2.

std::cout<<(i<4?i+9:i-3)<<(i<3?"am":"pm")
    <<'\t'<<(schedule[i]?"Booked":"Available")<<std::endl;

Try rephrasing this using multiple statements.
It might do what you want (then again, it might not), but the chances of being able to debug it / explain it / change it if it doesn't do what you want are slim.

In particular, try and do something not involving lots of (ab)use of the ?: operator.

The compiler doesn't care whether you cram everything onto one line, and use as few characters as possible, but all your human readers just find such coding hard to read.

When I see a post with a large block of code with absolutely no whitespace, I don't even bother reading any further.
