GUI Simple Calculator Visual C++ Source : Windows Form Application

Today let’s work around a new interesting visual C++ (cpp) calculator with Graphical User Interface (Windows Form Application). I made this source as easier as possible. You can compile the source by downloading the project source from below.

Why is it simple calculator? It has only the basic functions of a calculator such as addition, subtraction, multiplication,division and 2 others. First Entered number is taken to the first variable a. Then select and operator, enter the second number. Do the necessary operations and When you press “=” equals button, you can see the answer right where you expect it.

More than these basic operations, you can also find the square and square root of a number. I have added buttons for this. This program make use of “math.h” which contains “sqrt()” and “power()” functions for accomplishing these tasks.

Let me know your feedback in the comments.

Use visual c++ 2010 compiler for execution.

Energy – mass Converter program c++ (cpp) source

This is a Simple C++ code for a converter program that converts energy into mass according to the famous equation from greatest scientist Albert Einstein. E= MC²

Input energy in MeV( Mega electron volt), GeV( Giga electron volt) or in Tev( Tera electron volt).

You can use visual c++ compiler for compiling and running program. You can find the Source code below. if you are using Borland turbo C++ don’t use “using namespace std;” and insert .h extension for iostream, iomanip header files. Moreover, it will not support “system(“CLS”);” and replace it by “clrscr();”

E= MC²: –

E = Energy

M = Mass

C = speed of light in vacuum (299792458 m/s)

Let’s imagine the practical use of this equation. Consider just a stone, which weigh 250g. If you convert it completely into energy, then the total energy from the mass;

E = 0.250(kg) x 89875517873681764 (c x c)

= 22468879468420441 J

Sub shell Electron Configuration Calculator Cpp (C++) Source

There are 118 elements in our periodic table, which is the base of science. Each element has its own characteristic properties depending upon its electronic configuration. So finding electronic configuration of elements is very important.

Here is a C++ program for a sub shell electronic configuration calculator. By just typing the atomic number you can get the sub shell electronic configuration of the element. The sub shells are arranged in the increasing order of its energy. This is a windows console application. You can use visual C++ compiler to compile this program. You can download the C++ file and console .exe application from the link below.

Student Record C++(cpp) Source Code Windows Console Application

Let’s have a look at C++ source code for a student record program developed for windows console mode. You can test this code using Microsoft visual C++ compiler without any issues. I believe this sample code will help you to understand some of the basic C++ functions.

This is a menu driven program. You can add a student, get a student’s mark by entering his roll number, get a student’s details or print a table of all student’s details. This program creates a “student.dat” file at the current directory (The path at which the executable located) to save details that you have entered. During the next execution of the program the data present in the file is taken in to the memory. For deleting all existing data, you can use ’99’ command in main menu. It just delete existing file and create a new one having no records, simply a blank file.
