Powerful "Online Code real-time compilation test" integrated development environment-ideone

Referring to the integrated development environment, everyone first came to the native installation of Eclipse or visual studion, etc., but there is no such a situation, We often need an integrated environment for different development languages or in order to verify the different features of different programming languages that require multiple language compilation environments or often have friends ask you to help him solve a program problem in one of the other languages and you happen to have this machine without installing the corresponding compilation environment. This time if there is a website can be opened directly in the browser to use it is more convenient ah, and Ideone is such an integrated compilation environment online, you do not need to install any software, open to use, and support all programming languages.

Let's take a look at Figure 1.

Figure 1 main programming languages supported by Ideone

It supports up to dozens of languages and basically includes all the languages that can be involved.

Below is an introduction to what is Ideone and how to use it.

What is Ideone?

Ideone is a online compiler and debugging tool which allows you to compile source code and execute it online in more than Programming languages.

Ideone is an online compilation and debugging tool that you can compile and execute on-line, with a supported programming language of over 80 languages.

How do I use Ideone?

Choose A programming language, enter the source code with optional input data ... and you is ready to go!

Just choose the programming language you want to use, then enter the code and optional parameters and click on execute to run your program.

Of course, you can also click on the registration site, register your execution history will be saved, and can upload code execution, as shown in Figure 2

Figure 2 Registration

Next, let's take a look at the actual use.

Let's start with the Java language as an example to write a Hello Word program.

Figure 3 First select our Java language

Figure 3 Choosing a programming language

Then, enter the code shown in Figure 4 and click the Run button to execute.

Figure 4 Executing the code

Once executed, we can see the results of the code execution, as shown in Figure 5:

Figure 5 Successful execution results

Let's say we deliberately change the code, for example we deliberately remove the last curly brace, and we'll see what the result is. As shown in Figure 6

Figure 6 a compilation error condition

We see that in the case of compilation errors, the prompt information at a glance, very convenient.
