Programming

The programming divides a problem into its basic components to solve it with a computer using coded instructions acceptable by the machine

Pseudocode

It is the language similar to the spoken language chosen by us to design algorithms

Later, this pseudocode will be useful to convert it to a specific programming language to create programs

Algorithm

It is an ordered and finite sequence of steps, free of ambiguity, whose operations are necessary to transform the initial data of a problem in the results you want to obtain

Being those that are the solution to a problem (there can be more than one algorithm, since the solution to a problem does not have to be unique) in a finite time

Example of algorithm

{PRE: option ='R ' or ' T', base > 0, height > 0}
algorithm areas
{POST: area = base * height if option ='R'; area =(base * height) / 2 if option ='T'}
variable
    option: character
    base, height, area: real
begin
    write ('Enter the type of figure R/T')
    read (option)
    write ('base = ')
    read (base)
    write (' height = ')
    read (height)
    if option = 'R' then
       area = base * height
    else
       area =(base * height) / 2
    endif
    write ('The area of the figure is ', area)
end

As seen in the example, from some data: option, base and height (which are described in the Precondition)

They are processed through a set of instructions, we obtain the information we wanted, the area of ​​the geometric figure (which is described in the Postcondition)

Therefore, information is not born or arises from nothing, it must be prepared from raw material, the data, through a process

Program

It is a finite set of instructions directly understandable by an information processing system: machinery, a computer, a tablet, a mobile phone

They will allow ordering the execution of the sequence of steps chosen to solve the given problem in finite time
