CodeHS was selected as one of three education technology companies to take part in the 2013 Innovation Challenge, part of the NBC Education Nation initiative. [6] Innovation Nation challenge participants CodeHS, Teachley, and GigaBryte participated in a series of challenges in October 2013, culminating in a live pitch contest broadcast live on NBC during the Education Nation Summit.
The language has also been implemented as Karel the Dog in JavaScript by CodeHS. Similar to the original language, this implementation features Karel in a grid world. Programmers use and build upon Karel's simple vocabulary of commands to accomplish programming tasks. Instead of putting and picking beepers, Karel the Dog puts and takes tennis ...
In the IEEE standard the base is binary, i.e. =, and normalization is used.The IEEE standard stores the sign, exponent, and significand in separate fields of a floating point word, each of which has a fixed width (number of bits).

BASIC (Beginners' All-purpose Symbolic Instruction Code) [1] is a family of general-purpose, high-level programming languages designed for ease of use. The original version was created by John G. Kemeny and Thomas E. Kurtz at Dartmouth College in 1963. They wanted to enable students in non-scientific fields to use computers.
Common elements of coding style include: Indentation and whitespace character use – Ensures consistent block structures and improves readability.; Naming conventions – Standardizes how variables, functions, and classes are named, typically adhering to camelCase, snake case, or PascalCase, depending on the language.
If-then-else flow diagram A nested if–then–else flow diagram. In computer science, conditionals (that is, conditional statements, conditional expressions and conditional constructs) are programming language constructs that perform different computations or actions or return different values depending on the value of a Boolean expression, called a condition.
Integer overflow can be demonstrated through an odometer overflowing, a mechanical version of the phenomenon. All digits are set to the maximum 9 and the next increment of the white digit causes a cascade of carry-over additions setting all digits to 0, but there is no higher digit (1,000,000s digit) to change to a 1, so the counter resets to zero.
