they permitted a programmer to ignore many low-level details of the computer’s hardware. Hence‚ in the mid-1950s a third generation of languages came into use. These algorithmic‚ or procedural‚ languages are designed for solving a particular type of problem. Unlike machine or symbolic languages‚ they vary little between computers. They must be translated into machine code by a program called a compiler or interpreter. The first high-level language‚ Fortran [Formula translation]‚ was developed (1953–57)

Linear programming is a technique which shows practical problems as a series of mathematical equations which can be manipulated to find the optimum or best solution. Blending is a graphical approach to linear programming which deals with resource allocation subject to constraints. It is a model which assists firms in deciding the best possible utilisation of limited resources. Each resource constraint is represented as a mathematical linear equation. A linear expression is an equation which links

Every detail of a project plan will not materialize as expected. The way the change control management works is when change happens whether it be scope‚ implantation of contingency plans‚ Improvement. The way the project team and management cope with the change in order to make sure the project is finished on time. What is a risk profile

effects are the most common way that a program interacts with the outside world (people‚ filesystems‚ other computers on networks). But the degree to which side effects are used depends on the programming paradigm. Imperative programming isknown for its frequent utilization of side effects. In functional programming ‚ side effects are rarely used. Functional languages such as Standard ML ‚ Scheme and Scala do not restrict side effects‚ but it is customary for programmers to avoid them. [3] The functional

A History of Computer Programming Languages The first programming languages predate the modern computer. From the first‚ the languages were codes. Herman Hollerith realized that he could encode information on punch cards when he observed that railroad train conductors would encode the appearance of the ticket holders on the train tickets using the position of punched holes on the tickets. Hollerith then proceeded to encode the 1890 census data on punch cards which he made the same size as the boxes
