Help about Menu Dev C ++

[kenetpascua]

I want to create a menu like this

Menu List Type -

1 for Bubble Sort
2 for Insertion Sort
3 Selection Sort
4 Stack
5 Queues

heres the code of bubble sort

#include <iostream.h>
#include <stdlib.h>

const int MAXSIZE = 10;

void bubbleSort(int arr[], int size);
void swap(int& x, int& y);

int main()
{
     int nums[] = { 1, 7, 5, 3, 15, 11, 13, 17, 21, 19 };
     int k;

     cout << "BEFORE SORT: ";
     for (k = 0; k < MAXSIZE; k++)
           cout << nums[k] << " ";

     bubbleSort(nums, MAXSIZE);

     cout << endl << endl;
     cout << "AFTER SORT: ";
     for (k = 0; k < MAXSIZE; k++)
           cout << nums[k] << " ";

     cout << endl << endl << endl;

     system("PAUSE");
     return 0;
}// end main()

void bubbleSort(int arr[], int size)
{
     int last = size - 2;
     int isChanged = 1;

     while (last >= 0 && isChanged)
     {
           isChanged = 0;

           for (int k = 0; k <= last; k++)
                 if (arr[k] < arr[k+1])
                 {
                       swap(arr[k], arr[k+1]);
                       isChanged = 1;
                 }
           last--;
     }
}// end bubbleSort()

void swap(int& x, int& y)
{
     int temp;
     temp = x;
     x = y;
     y = temp;
}// end swap()

Code for Insertion Sort

#include <iostream.h>
#include <stdlib.h>

void insertPosition(int arr[], int& size, int element, int position);

int main()
{
     int nums[10] = { 34, 12, 89, 22, 21, 45, 55, 93, 27, 76 };
     int size = 10;
     int element;
     int position;

     for (int k = 0; k < size; k++)
           cout << nums[k] << "  ";

     do
     {
           cout << endl << endl << "Enter the position in the array for insertion (0 - 9): ";
           cin >> position;
     } while (position < 0 || position > 9);

     cout << "Enter the value to be inserted into position [" << position
           << "] of the array: ";
     cin >> element;

     insertPosition(nums, size, element, position);

     cout << endl << endl;
     for (int k = 0; k < size; k++)
           cout << nums[k] << "  ";

     cout << endl << endl << endl;

     system("PAUSE");
     return 0;
}// end main()

void insertPosition(int arr[], int& size, int element, int position)
{
     for (int k = size - 1; k >= position; k--)
           arr[k+1] = arr[k];
     arr[position] = element;

     size++;
}// end insertPosition()

Code for Selection Sort

#include <iostream.h>
#include <stdlib.h>

const int MAXSIZE = 10;

void selectionSort(int arr[], int size);
void swap(int& x, int& y);

int main()
{
     int numbers[] = { 13, 5, 1, 7, 9, 11, 3, 17, 19, 15 };
     int k;

     cout << "BEFORE SORT: ";
     for (k = 0; k < MAXSIZE; k++)
           cout << numbers[k] << " ";

     selectionSort(numbers, MAXSIZE);

     cout << endl << endl;
     cout << "AFTER SORT: ";
     for (k = 0; k < MAXSIZE; k++)
           cout << numbers[k] << " ";

     cout << endl << endl << endl;

     system("PAUSE");
     return 0;
}// end main()

void selectionSort(int arr[], int size)
{
     int indexOfMin, pass, j;

     for (pass = 0; pass < size - 1; pass++)
     {
           indexOfMin = pass;

           for (j = pass + 1; j < size; j++)
                 if (arr[j] < arr[indexOfMin])
                       indexOfMin = j;

           swap(arr[pass], arr[indexOfMin]);
     }
}// end selectionSort()

void swap(int& x, int& y)
{
     int temp;
     temp = x;
     x = y;
     y = temp;
}// end swap()

Code for Stack

#include <iostream>
#include <list>

using namespace std;

int main()
{
list<int> iL;
int k;

// load the stack with numbers 0 to 9, last number entered would be on top
for(k = 0; k < 10; k++)
iL.push_front(k);

// now unload the stack and display
cout << "Unloading the stack in order:\n";
for(k = 0; k < 10; k++)
{
// read the top element of the list
cout << iL.front() << endl;
// now pop it (removes top element)
iL.pop_front();
}

cin.get(); // wait
return 0;
}

Code for Queues

#include <iostream.h>

struct Node{
	int data;
	Node *prev;
	Node *next;
};

class TQueue{
public:
	TQueue(){
		head = NULL;
		currItem = NULL;
	}

	~TQueue(){
		delete [] head;
	}

	void AddItem(int Data){
		Node *prevItem = 0;
		Node *newNode = new Node;
		newNode->data = Data;
		if(head == NULL){
			head = newNode;
			currItem = head;
			head->next = NULL;
			head->prev = NULL;
		}
		else{
			currItem = prevItem = head;
			while(currItem->next != NULL){
				currItem = currItem->next;
			}
			currItem->next = newNode;
			currItem = currItem->next;

			while(prevItem->next != currItem){
				prevItem = prevItem->next;
			}
			currItem->prev = prevItem;
		}
	}
	
	int GetItem(){
		if(!IsEmpty()){
			if(currItem->prev != NULL){
				currItem = currItem->prev;
				return currItem->next->data;
			}
			else
				return currItem->data;
		}
		else
			return 0;
	}

	bool IsEmpty(){
		return (head == NULL);
	}
private:
	Node *head;
	Node *currItem;
};

int main(){
	TQueue tester;
	tester.AddItem(353);
	tester.AddItem(53);
	tester.AddItem(563);
	cout << tester.GetItem() << endl;
	cout << tester.GetItem() << endl;
	cout << tester.GetItem() << endl;
	cin.get();
	return 0;
}

Sample If I press 1 then the bubble sort appears

then if I press 2 Insertion Sort appears thx

then 3 4 5

bump!

Don't really understand what you want to do. Do you want to display a menu and execute the corresponding program???

You should put the program into a whole one. The program simply can't know the filename.

Give you a simple way to draw a menu:

#include <iostream>

using namespace std;

int main () {
    char option;
    for(int i=0;i<3;i++){
        cout<<" Menu"<<endl
            <<"======"<<endl
            <<"[1] Say hello"<<endl
            <<"[2] Say good morning"<<endl
            <<"[3] Say bye!"<<endl
            <<endl
            <<"Please enter your choice> ";
        cin>>option;
        switch(option){
            case '1':
                cout<<"Hello!\n\n";
                i=-1;
                continue;
            case '2':
                cout<<"Good morning!\n\n";
                i=-1;
                continue;
            case '3':
                cout<<"Bye!\n\n";
                return 0;
            default:
                cout<<"Invalid option! "<<(2-i)<<" more trying."<<endl;
        }
    }
    cout<<"Too bad... 3 times passed. Bye!";
    return 0;
}
