I'm learning OpenGL recently and I want to work with GLSL in my codes.
I want to know where should I write the codes?
Is there an IDE or something?
Or should I write them some where in my source code?
what should I do for writing a simple shading program?
Thanks alot.
You can write GLSL code to anywhere you want. Just open a text file and write the code in there. Than you are gonna load the file and compile it from your source code. Alternatively you can embed the shader source into the source code with raw string literals if your language supports them.
You can find a basic example for writing and compiling in this tutorial. Programming language you use doesn't matter for compiling since it's done in OpenGL.

I'm a bit new to programming and I just wanted to know if there can be any problems if I send my C++ code I wrote on Eclipse to a friend who works on VC++?
Yes, there can be problems.
Whether the code can simply be copy/pasted to another toolchain entirely depends on how standard-compliant and portable the code is.
We cannot guess at that from here.
There should be no problem as long as you are not using any compiler-specific things, which is unlikely if you are a beginner.

Let's say we've got a first program called Program1.exe which contains the necessary information to create and compile another application called Program2.exe. Actually it could also load that information from a txt file or whatever.
Googling, I've found that this is "easy" to do in C#, using Visual Studio:
How to programatically build and compile another c# project from the current project
Programmatically Invoke the C# Compiler
The problem is that I'm not using (and can't use) C#, but C++. Summing it up, my question is if that I can do this same thing using C++.
I would prefer to do it without additional libraries, but if that's not possible, or if it's too hard to do, you can also recommend any library allowing it.
I think you'll probably have noticed it, but my goal is to use it under Windows so I don't care if it's not portable.
Thanks everybody.
It's trivial (if maybe a bit odd) for a C++ program to compile and run another based on code stored in a text file. Debugging that other program, however, isn't.

I'm a beginner C++ programmer.I would like to know that Is it possible to output to console windows without using iostream header file?
the answer of the question is actually Yes ! but How?
You can always delve down to the C library level, using e.g. printf.
If you don't want to use the standard library at all then you have to use platform-specific functionality. In Windows there are many layers here, much like the C++ versus C layers in the standard library. The highest Windows API layer is the WriteFile function, and below that, WriteConsole, then perhaps WriteConsoleOutput, so on, check it out.
Note that there are at least two open source projects to provide more reasonable console functionality in Windows, namely Console2 at SourceForge and mintty at Google Code.

I want to put C/C++ code into Objective C programs.
What's the exact way to do that ?
I've tried many times.
So, if someone know how to that, please explain the way from zero (from a empty project) and give me some class examples ;)
(i work on Xcode 5.0.2)
Thank you !
Using XCode, rename the file extension of the files with C++ code from .m to .mm for C++.
Objective C is a superset of C, so pure C code will compile without any required changes.

I am given a task to develop an C++ command-line(terminal, I am using, will run the program in Linux/Ubuntu) display. But I dont like the command-line design, is there anyway to improve the UI design?
Note: I must run the program in terminal!!
ncurses. It's a lib to be able to put text wherever you want in the terminal, so you can effectively draw, ascii-art style in the terminal. It's also a very old library, so it may be a little tedious to use.
I developed a simple multiplatform console management library some time ago.
You can use it at least on Linux and Windows. It uses native calls in Windows, and standard escape codes in other platforms.
If you just want to show some colors, position the cursor, and so on, you can use it in a matter of minutes without struggling with ncurses.
