    C++ Library Management Software with Source Code

    Believe me, building a library management software in C++ is always a difficult thing. I have done library management software in java, c# and felt so much easiness in getting things done. Yet, this was my first library management software. Here I am going to share a simple library management program in C++ / Cpp as console application for schools and colleges. This program took me around 4 months to complete. The code is written as simple as possible. During the initial stage there were only just book issue and book submission modules. Later i have added more and more functions to improve Library Assistant. Thanks to Object Oriented Programming.

    Features

    Simple and easy User Interface
    Dasboard
    Ability to add and edit students, books
    Add New Student Window
    Dedicated Admin Panel
    Admin Panel
    Barcode Reader Support

    Bar code is supported for book issue and book submission process.

    Organize Members by their Class / Level
    Member Organization
    Library Overview Panel on Startup
    Library Overview
    Multithreaded book and member search
    Multithreaded Book Search
    Single-click Book Submission
    Easy to use book submission

    How to run the program ?

    1. Download the zip file from above link
    2. Run Library Management System.exe
    3. The default password is ‘PPM’ (case sensitive).
    4. Done !

  • C++ program to find the largest and second largest number present in an array

    C++ program to find the largest and second largest number present in an array

    C++ program to find the largest and second-largest numbers present in an array along with their location index on the array. This program first find the largest number by going through all the numbers in the array. It stores the index of the largest number on the variable pos1 and largest number is the largest variable. A second for loop is applied, which also check for the largest number. When it hits on the largest found by the first loop, it is bypassed using a continue statement and hence will get the second-largest number.

    #include <iostream>
#include <conio.h>
using namespace std;

void main()
{
	int a[10], i, largest = 0, second_largest = 0, pos1, pos2;
	int n;
	cout << "Enter Number of elements :";
	cin >> n;
	for (i = 0; i < n; ++i)
	{
		cout << "n Enter " << (i + 1) << "th Element :";
		cin >> a[i];
	}
	//Finding Largest
	for (i = 0; i < 10; ++i)
	{
		if (a[i] > largest)
		{
			largest = a[i];
			pos1 = i;
		}
	}
	//finding second largset
	for (i = 0; i < 10; ++i)
	{
		if (a[i] > second_largest)
		{
			if (a[i] == largest)
				continue;	//Ignoring largest in order to get second largest
			second_largest = a[i];
			pos2 = i;
		}
	}
	cout << "nn Largest Number :" << largest << " at position " << (pos1 + 1);
	cout << "nn Second Largest Number :" << second_largest << " at position " << (pos2 + 1);

	getch();
	return;
}

  • C++ Program to Exchange Values of Two variables using Pointer

    C++ Program to Exchange Values of Two variables using Pointer

    C++ program to exchange values of two variables (Swapping) using pointer. This program uses a function called exchange(int*,int*) that takes two argument as integer pointers. The variables are passed by reference method and hence, the swapping done at the exchange function will reflect in the main method also.

    #include<iostream>
    #include<conio.h>
    using namespace std;
    void exchange(int*, int*);
    void main()
    {   
            int x,y;
            cout<<“Enter x :”;
            cin>>x;
            cout<<“nEnter y:”;
            cin>>y;
            cout<<“Before Exchange : x = “<<x<<” y = “<<y<<“nn”;
            exchange(&x,&y);  //Calling Exhcange function to swap
            cout<<“After Exchange : x = “<<x<<” y = “<<y<<“nn”;
            getch();
    }
    //No need to return any values since the variables are already affected.
    void exchange(int *a, int *b)
    {
            int t;
            t = *a;   //Saving data in first variable to an intermediate one
            *a = *b;  //Saving second variable to first
            *b = t;   //Saving intermediate variable to second
    }
