South African Computer Olympiad
The South African Computing Olympiad (SACO) is an annual computer programming competition for secondary school students (although at least one primary school student has participated) in South Africa. The South African team for the International Olympiad in Informatics is selected through it. Competition rounds The competition consists of three rounds. The first is a pen-and-paper aptitude examination at the entrant's school, testing a combination of general knowledge, computer knowledge, problem-solving and basic programming. (Entrants are often required to program an imaginary robot in a fictional Logo-like language.) Although the first round is not compulsory, it is accessible to those who do not have access to, or knowledge of, computers. 31,926 students entered it in 2006. In the second round, actual programs must be written and executed. There are five questions, each requiring a different program to be written. Most entrants answer only a single question. The tasks usually i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Programming
Computer programming or coding is the composition of sequences of instructions, called computer program, programs, that computers can follow to perform tasks. It involves designing and implementing algorithms, step-by-step specifications of procedures, by writing source code, code in one or more programming languages. Programmers typically use high-level programming languages that are more easily intelligible to humans than machine code, which is directly executed by the central processing unit. Proficient programming usually requires expertise in several different subjects, including knowledge of the Domain (software engineering), application domain, details of programming languages and generic code library (computing), libraries, specialized algorithms, and Logic#Formal logic, formal logic. Auxiliary tasks accompanying and related to programming include Requirements analysis, analyzing requirements, Software testing, testing, debugging (investigating and fixing problems), imple ...

Pascal Programming Language
Pascal is an imperative and procedural programming language, designed by Niklaus Wirth as a small, efficient language intended to encourage good programming practices using structured programming and data structuring. It is named after French mathematician, philosopher and physicist Blaise Pascal. Pascal was developed on the pattern of the ALGOL 60 language. Wirth was involved in the process to improve the language as part of the ALGOL X efforts and proposed a version named ALGOL W. This was not accepted, and the ALGOL X process bogged down. In 1968, Wirth decided to abandon the ALGOL X process and further improve ALGOL W, releasing this as Pascal in 1970. On top of ALGOL's scalars and arrays, Pascal enables defining complex datatypes and building dynamic and recursive data structures such as lists, trees and graphs. Pascal has strong typing on all objects, which means that one type of data cannot be converted to or interpreted as another without explicit conversions. Unlike ...

C (programming Language)
C (''pronounced'' '' – like the letter c'') is a general-purpose programming language. It was created in the 1970s by Dennis Ritchie and remains very widely used and influential. By design, C's features cleanly reflect the capabilities of the targeted Central processing unit, CPUs. It has found lasting use in operating systems code (especially in Kernel (operating system), kernels), device drivers, and protocol stacks, but its use in application software has been decreasing. C is commonly used on computer architectures that range from the largest supercomputers to the smallest microcontrollers and embedded systems. A successor to the programming language B (programming language), B, C was originally developed at Bell Labs by Ritchie between 1972 and 1973 to construct utilities running on Unix. It was applied to re-implementing the kernel of the Unix operating system. During the 1980s, C gradually gained popularity. It has become one of the most widely used programming langu ...

Western Cape
The Western Cape ( ; , ) is a provinces of South Africa, province of South Africa, situated on the south-western coast of the country. It is the List of South African provinces by area, fourth largest of the nine provinces with an area of , and List of South African provinces by population, the third most populous, with an estimated 7 million inhabitants in 2020. About two-thirds of these inhabitants live in the metropolitan area of Cape Town, which is also the provincial capital. The Western Cape was created in 1994 from part of the former Cape Province. The two largest cities are Cape Town and George, Western Cape, George. Geography The Western Cape is roughly L-shaped, extending north and east from the Cape of Good Hope, in the southwestern corner of South Africa. It stretches about northwards along the Atlantic coast and about eastwards along the South African south coast (Southern Indian Ocean). It is bordered on the north by the Northern Cape and on the east by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Java (programming Language)
Java is a High-level programming language, high-level, General-purpose programming language, general-purpose, Memory safety, memory-safe, object-oriented programming, object-oriented programming language. It is intended to let programmers ''write once, run anywhere'' (Write once, run anywhere, WORA), meaning that compiler, compiled Java code can run on all platforms that support Java without the need to recompile. Java applications are typically compiled to Java bytecode, bytecode that can run on any Java virtual machine (JVM) regardless of the underlying computer architecture. The syntax (programming languages), syntax of Java is similar to C (programming language), C and C++, but has fewer low-level programming language, low-level facilities than either of them. The Java runtime provides dynamic capabilities (such as Reflective programming, reflection and runtime code modification) that are typically not available in traditional compiled languages. Java gained popularity sh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free State (province)
The Free State ( ; ; ; ; ), formerly known as the Orange Free State, is a Provinces of South Africa, province of South Africa. Its capital is Bloemfontein, which is also South Africa's judicial capital. Its historical origins lie in the Boer republic called the Orange Free State and later the Orange Free State (province), Orange Free State Province. History The current borders of the province date from 1994 when the Bantustans were abolished and reincorporated into South Africa. It is also the only one of the four original provinces of South Africa not to undergo border changes, apart from the reincorporation of Bantustans, and its borders date from before the outbreak of the Boer War. Geography The Free State is situated on a succession of flat grassy plains sprinkled with pastureland, resting on a general elevation of 3,800 feet only broken by the occasional hill or kopje. The rich soil and pleasant climate allow for a thriving agricultural industry. The province is high ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Delphi (programming Language)
Delphi is a general-purpose programming language and a software product that uses the Delphi dialect of the Object Pascal programming language and provides an integrated development environment (IDE) for rapid application development of desktop, mobile application, mobile, web application, web, and console application, console software, currently developed and maintained by Embarcadero Technologies.

Programming Language
A programming language is a system of notation for writing computer programs. Programming languages are described in terms of their Syntax (programming languages), syntax (form) and semantics (computer science), semantics (meaning), usually defined by a formal language. Languages usually provide features such as a type system, Variable (computer science), variables, and mechanisms for Exception handling (programming), error handling. An Programming language implementation, implementation of a programming language is required in order to Execution (computing), execute programs, namely an Interpreter (computing), interpreter or a compiler. An interpreter directly executes the source code, while a compiler produces an executable program. Computer architecture has strongly influenced the design of programming languages, with the most common type (imperative languages—which implement operations in a specified order) developed to perform well on the popular von Neumann architecture. ...
