Code Review: Payroll Management System

Compiler or Tool: Turbo C

Programming Language: C++

User Interface Type: CUI [Character User Interface]

Description:

This Payroll Management System allows staff to maintain their employees- database with details such as their name, designation, age, address etc. Even though the system is medium size it teaches how to code simple file handling support system with intuitive menu in C++ language.

The System contains 3 classes, employee class with following properties and methods:

The main() function presents main menu and becomes single point entry and exit code. The main() function call graph is as follows:

The menu presented by this main() function is as follows:

The system uses basic commands to arrange data on screen and 2 classes and 1function are used to manage the system. To study the code includes how files are read and write with very fancy menu.

Total code lines for this system are 1526 lines [approximately]. It is a most suitably called as mini project in C++ language.

If you want to write or construct or program C++ mini-project and do not know how or from where to start buy this simple e-book: Code Review of 26 C++ mini-projects.

C++ Code Review: Swaps two numbers using pointer.

Description: This program swaps two numbers using pointer.

Code:

//Compiling Tool: Code::Block IDE with MinGW

//Program swaps two numbers using pointer

 

#include<iostream>

#include<conio.h> //for getch()

 

using namespace std;

 

main()

{

    int* a = new int;

    int* b = new int;

 

    cout << "Enter value of a and b:";

    cin >> *a >> *b;

 

//put a in temp

    int* temp = a;

//put b in a

    a = b;

//put temp, was a, into b
