    need help for stack problem

    can anyone help me with creating the h file.please help me.
    this is about garage parking:

    There is only one entrance/exit to the garage. If someone comes to retrieve a car that is not first out of exit, all cars blocking its path must be moved out (hence the stack). After the car is taken out, all other cars are restored in order they were taking out. Each line of the input file contains an "A" for arrival or "D" for departure, a license plate number (6 characters) and the time of arrival or departure.
    The program should print a message whenever a car arrives or departs. When a car arrives, the message should specify the time of arrival and whether or not there is room for the car in the garage (10 car limits).
    sample output:

    Car with license no. DT3172 arriveg at 8:01 AM car parked

    Car with license no. BFD111 arriving at 12:52 PM no room available

    Car with license no. BFD111 deparing at 1:33 PM no such car parked here

    Car with license no. DT3172 departing at 2:59 PM
    times moved: 2
    time parked: 6 hours and 58 minutes

    Note: when calculating the time parked, first convert the time of arrival and the time of departure to military time.

    Note: use stack

    Code:
    #include <iostream>
    #include <fstream>
    #include "garage.h"
    #include <stack>
    
    
    using namespace std;
    
    const int MAX = 10;
    
    void main()
    {
    	ifstream infile;
    	stack garage;
    	char AorD;
    	char AorP[2];
    	char plate [MAX];
    	int hour;
    	int min;
    
    	infile.open  ("garagepark.txt");
    
    	if (infile.fail ())
    	{
    		cout << "Inut file open failed." <<endl;
    		exit(1);
    	}
    
    	infile >> AorD>>plate>>hour>>min>>AorP;
    
    	while (infile)
    	{
    		if (AorD == 'A')
    			garagepark.Push;
    		else
    			if (AorD == 'D')
    				garagepark.Pop;
    			infile >> AorD>>plate>>hour>>min>>AorP;
    	}
    	infile.close();
    
    }
    Code:
    #include <iostream>
    #include "garage.h"
    #include <string>
    
    using namespace std;
    
    string MAXCAR;

    Presumably you have to declare the GarageStack class. What do you have so far?

    GarageStack

    this is for GarageStack, but I don't know it is correct or not?

    Code:
    #ifndef GARAGE_H
    #define GARAGE_H
    
    
    const int MAX_CARS=10;
    
    
    class GarageStack
    {
    public:
    	bool IsEmpty() const;
    
    	bool IsFull() const;
    
    	void Push(/* in */ int newItem);
    
    	//int Top() const;
    
    	void Pop();
    
    	IntStack();
    
    private:
    	struct car
    	{
    		char firstLetter;
    		char plate;
    		//i need a time spot here
    		//and here one for arrival and one for departure.
    		int timesMoved;
    	};
    	car data[MAX_CARS];
    	int top;
    };
    #endif

    Looks like you still have a little more updating to do. Look at the function definitions in GarageStack.cpp. Your function declarations in GarageStack.h should match them with the same parameters and return type.

    Also look at the names of the variables used in the cpp file. The ones that aren't funcion parameters are probably member variables. Make sure you have a match in your header.

    Add declaration of GarageStack::GarageStack() into class declaration.
    Than read all functions in your c-file and add their declaration (if missing) to the class declaration
    The first 90% of a project takes 90% of the time,
    the last 10% takes the other 90% of the time.

    If we show you, then we are doing the assignment for you. Is there something you didn't understand in my instructions?

    Your push() and pop() are way way too complicated for a stack.

    The isempty() test is good, but apart from that, you only need this

    Code:
    push( item ) { stack[stackptr++] = item; }
    pop ( ) { return stack[--stackptr]; }
    All that logic you have in there has to go somewhere else.

    So if you remove a car from the stack, you can do these things
    - push it back to the stack you just took it from
    - push it back to another stack of cars
    - finish with it

    Like removing cars requires two stacks (that's a big hint)
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    Get a bunch of paper plates, library index cards, post-it notes or whatever, then write down your car registrations on each one.

    Then use the rules for a stack (add and remove from one end only) to add and remove them from the garage.

    Observe how each piece of paper moves

    Then do the same in software.

    I asked a specific question. If you can answer my question, I might be able to give you more help.

    for push or pop do I have to use this:
    Push(AorD,plate,hour,min,AorP);
