C/C++.
It is much more difficult for a new programmer to move from Python (or even Java) to C/C++ than vice versa. Becoming knowledgeable and proficient in C/C++ will give you the tools you need to pick up other languages such as Python very easily and quickly. This is besides for the fact that Python itself is usually implemented in C (or, more rarely, Java) and it helps to know how C-type languages work beforehand.

Python. The reason is you can do so many useful things which will inspire you, where as it's a long time before you can create a genuinely useful C++ program. Definitely do not start with C++. FORTRAN is a great first language but nobody uses it in finance.
I'd start with Python, then move onto C++.

C++ is among the worst first languages to learn. In terms of bad choices, it's right up there with VisualBasic. If you want to code close to metal, learn C first. Then carefully select a subset of C++ that works for you.
...
Google uses a subset of C++. They don't use things like automatic ref counted pointers or multiple inheritance.
You can basically think of Google's C++ subset as C plus a bit of sugar:
In general, this makes the code cleaner without adding much complexity.

If you want to be productive and need a language that is versatile enough to span prototyping, administration, modeling, and data munging, learn Python first. You'll have a reasonable object model along with functional constructs that will help you understand a wider variety of languages in the future (eg ML, Haskell, Clojure).

- Basic single inheritance.

- Scope based resource management.

This reminds me of a discussion we have recently over whether it's still worth it to learn C.
I'm also glad that Daniel Duffy has the foresight to dedicate the first two levels in our online C++ certificate to teach C. I know a lot of students questioned that mightily but I'm sure it will serve them well in the long run.
It's pretty tempting as a beginner to take a shortcut and jump to the latest, most fashionable language at the moment, be it C#, F#, Ocaml, whatever but it's good to build a strong foundation first. And it's clear that one needs to be versatile and should know more than just one language.

many people know how to code. but few know how to code cleanly. the mess of code created ultimately leads to confusion among developers, resulting in bugs, memory hogs, errors and even crashes. if i were to recommend a book to become a good developer it would be Clean Code, Head First Design Patters and books on unit testing. And oh, a good developer always write unit tests before implementing the actual codes.

While I am sure that is a useful book, I highly doubt it would be of any use to the OP right now, who is looking to begin to learn programming

hi, haven you seen the contents of these books? i too am surprised at how the authors managed to present programming concepts at such understandable and simple level using simple examples. source codes provided.
afterall, you don't learn how to swim just by reading a book.

People are going to hate me for saying this, but use Codeblocks: http://www.sci.brooklyn.cuny.edu/~goetz/codeblocks/
It is the simplest, cleanest, and requires nothing but a simple installation. From all of the compilers I have ever used this is the easiest. Might not be a hard-core programmers choice, but I love its simplicity.
nkabir, you're a pretty hard core programmer. I think he just wants exposure to:
- Loops
- Functions
- If-Statements
- etc.
To everyone else:
I am decent at C++ and a complete beginner at Python but from what I have seen so far it is pretty awesome. But as a first language? Going from C++ to VBA took me less than a week to write some decent code because I was so familiar with all the concepts. Python is so different from all of the other languages out there...

Go with C++, sooner you introduce yourself with languages like C++/Java better for you. Rest you can learn easily.
I don't think Python is so different. You pick up basics easily. May be for further expertise it requires a bit of effort.
Compare it with learning anyone of those functional programming.

Why do you say that? The differences I can see are that Python is a scripting language (versus compiled for C++), that it doesn't need a main() method, and that it doesn't have call-by-value (as everything is an object). Otherwise both Python and Ruby offer a painless introduction to both imperative and object-oriented styles. If you want to get quickly into implementing data structures and algorithms, I can think of at least four books that teach it in Python. There is a reason why schools like MIT and CalTech teach Python as a first language.

And Berkeley and Stanford. Python is coherent enough to be taught to children yet scalable enough to run Google's infrastructure and flexible enough for AQR and Citadel.
...
It all got started, I believe, because the very earliest Googlers (Sergey, Larry, Craig, ...) made a good engineering decision: "Python where we can, C++ where we must" -- they used (a subset of) C++ for the parts of the software stack where very low latency and/or tight control of memory were crucial, and Python, allowing more rapid delivery and maintenance of programs, for other parts.
...
If you actually want to get work done, learn Python first. If you want to talk about how awesomely fast your quirky C++ code will be, by all means, learn it. But you're going to be surpassed in performance by people that use FPGAs and microwaves and surpassed in productivity by people that know shell and scripting languages.
...
The task:
Read a file of text, determine the n most frequently used words, and print out a sorted list of those words along with their frequencies.
Knuth came up with a typically clever, lengthy, low-level implementation [...]. McIlroy then somewhat perversely wrote a six-line shell script that did the job, basically changing the subject away from literate programming and toward a critique of Knuth’s doing something low-level and complicated when unnecessary.
...
The speed game has since moved on to electrical engineering and physics. And all those people may be shut down by congress.

- Python discourages loops in general and loops are core to MOST languages.
- Python does many things very differently, like being contained in functions/classes is dependent on word SPACING, not closers or "End Loop".
- If you search for even simple code in Python online you will see that the hard-core Python programmers use some funky way to program them and not at all traditional methods
Again, nkabir: I don't dispute that it is better. And if the OP was asking "what is the ONLY language I should learn?" I would agree with you. But if he intends on learning other languages C++ is similar to most other languages.

Do you think there is anything wrong with the C++ loops, do while, if-else statements? If not, I don't think the OP will go way beyond that. I got as far as "what a Class is" in Programming 101 in undergrad...
