Save this as a .cpp file with a name that accurately reflects your program. Don't confuse there are many other extensions for C++ files, choose any of them (like *.cc, *.cxx, *.c++, *.cp) .
- Hint: It should say Save as Type: {select "All Files"}
4

Compile it. For users of linux and gcc compiler, use Command : g++ sum.cpp. Users of Window can use any C++ compiler, such as MS Visual C++,Dev-C++ or any other preferred program.
5

Run the program. For users of Linux and gcc compiler Command : ./a.out (a.out is an executable file produce by compiler after compilation of program.)

Question

Are there online solving programs?

Yes, there are many types of online solving programming tests available on the internet.
Question

What are the uses of C++?

Everything! It can be used in everything from programming games to making webpages, software, and databases.
Question

I'm interested in learning C++, but I don't have any money. What can I do?

Look for tutorials like this one online and teach yourself.
Question

How would I know which data type I'm supposed to use?

Think about what the data needs to do. For example, if you need to do something like simple counting or a loop, use int. If you need to keep track of multiple characters, use a string.
Question

How can I learn programming using C++?

Sebir Moran

Community Answer

Watch some tutorials on YouTube. Or buy a book on C++ programming like Sumita Arona's Programming with C++.
Question

What are the steps to start C++ programming?

If you know C you can can easily learn C++. There is no much difference in C & C++.
Question

How can I create a program that stores school records through C++?

Community Answer

The simplest way is to use the standard input method (cin) to get the user's input, then store it in a file using fstreams.
Question

How can I learn C programming in a simple way?

You can watch YouTube tutorials and follow along: that goes a long way. Alternatively, you could join a program such as Treehouse or Cademy. You could also pick up a book and read about C++.
Question

I want to create a program that allows my customers to search all the products in my store. What do I need to know to do this?

Are Lodgaard

Community Answer

You need to learn a programming language and some type of server language.
Question

Is C++ a better language than C#? If so, why?

They're both object oriented, and similar in many ways, but I can't say which one is better. C# is a little easier to learn, and widely used for most business-oriented applications nowadays, but it doesn't have the same "power" as C++.

cin.ignore() prevents the program from ending prematurely and closing the window immediately (before you have time to see it)! Press any key if you want to end the program. cin.get() functions in a similar manner.

Thanks for submitting a tip for review!

Your program will crash if you try to input alphabetical values to one of the "int" vars. Since no propper error trapping is done your program can't convert the values. Better read string or catch your exceptions.
Make sure to stay as far away from Dev-C++ as possible, because it has multiple bugs, an outdated compiler, and has not been updated since 2005.

Things You'll Need

A text/code editor (e.g. vim, notepad, etc).
A compiler.
Alternatively, an IDE contains an editor and a compiler.
Turbo c
Codepad online
Notepad++
