It is much more fun and you will understand the thrill in programming . However you can still write code in python , which is also good for beginner , but keep it later first have a visit to the "Land Of QBASIC". :) Pascal is good language but it is probably not used nowadays.
The demise of Pascal is IMHO mainly caused by Borland sticking to it's GUI way of working, while its customers moved on to the Web. Borland never had a really attractive offer for server-side development.
Syntax. Syntactically, Pascal is much more ALGOL-like than C. ... However, C is more ALGOL-like than Pascal regarding (simple) declarations, retaining the type-name variable-name syntax.
In short, C# is statically typed, can do more, is faster, but takes more time to learn and type. ... C# ('C-Sharp') and Python are both object-oriented, high-level, and easy languages to learn and code. They offer fast development and good performance and are both highly relevant languages in most fields.
Very Long Term History
While the calculations do happen and are essential to the successful running of the program, the programmer does not need to know how they are done. People who program video games probably need more math than the average web designer. ... (Here's a good overview of the math skills required for entry-level coding.
Binary (or base-2) a numeric system that only uses two digits — 0 and 1. Computers operate in binary, meaning they store data and perform calculations using only zeros and ones. A single binary digit can only represent True (1) or False (0) in boolean logic. ... One bit contains a single binary value — either a 0 or a 1.
binary
The circuits in a computer's processor are made up of billions of transistors . A transistor is a tiny switch that is activated by the electronic signals it receives. The digits 1 and 0 used in binary reflect the on and off states of a transistor.
Computers don't understand words or numbers the way humans do. ... To make sense of complicated data, your computer has to encode it in binary. Binary is a base 2 number system. Base 2 means there are only two digits—1 and 0—which correspond to the on and off states your computer can understand.
Machine language
Converting to and from a decimal will be covered in another article. For now, we will answer why computers use the binary (“base 2”) number system and why electronic devices store binary numbers. ... The very first computers used binary numbers, and they are still used today.
A transistor is a basic electrical component that alters the flow of electrical current. Transistors are the building blocks of integrated circuits, such as computer processors, or CPUs. A series of transistors may also be used as a logic gate when performing logical operations. ...
Moore's Law is alive and well through a variety of design innovations – despite the now sedate pace at which components are continuing to shrink. But it's the performance increases - the speed gains that come from denser integrated circuits – that most people focus on when it comes to Moore's Law.
Currently transistors are around 10-20 nanometers in scale, and are expected to shrink to around 5-7 nanometers in the next few years, but that's seemed to be about far as we can go. At that point, transistors are so small that quantum effects prevent them from working properly.
A transistor can then store a bit. The transistors are organized in groups of 8, so each group can store a byte. A single integrated circuit may have millions of these groups. ... They have a battery that keeps enough power to the memory transistors that they don't forget.

The byte was originally the smallest number of bits that could hold a single character (I assume standard ASCII). We still use ASCII standard, so 8 bits per character is still relevant. This sentence, for instance, is 41 bytes. That's easily countable and practical for our purposes.

Integers are commonly stored using a word of memory, which is 4 bytes or 32 bits, so integers from 0 up to 4,(232 - 1) can be stored.
Like a byte is a group of 8 bits, a buffer is a group of a pre-defined number of bytes. If we have a group of 3 bytes, this could either represent 3 values between 0 and 255, but also one single value between 0 and (2563).
one byte
8 Answers. Strictly speaking, the term "byte" can actually refer to a unit with other than 256 values. It's just that that's the almost universal size. ... The de facto standard of eight bits is a convenient power of two permitting the values 0 through 255 for one byte.
