- 1Set of instructions, commands, orders or procedures written in a programming language in order that the computer can perform certain tasks in a correct wayProgram
- 2Must have the following conditionsExact, clear, efficient and portable
- 3It is the methodology to do programs During this process, the program is written according to the syntax of programming language It is tested, debugged, implemented and is given maintenanceProgramming
- 4Is written by professionals known as programmersThe code of the programs
- 5It is the set of symbols, letters and syntax rules that controls the physical and logical behavior of a computer Permits the programmer, among other things, to specify data that will be processed and stored on itProgramming language
- 6Stage 1 of programming Are located in an introductory level of programmingPhase 1 Definition of the problem:
Where the problem is define clearly
Phase 2 Analysis of the problem
Think in the operations needed
-Input, process, output-
Phase 3 Design
-Algoritm
-Flow chart
-Test - 7Stage 2 of programming Pretend that you have a complete vision where carries out this processPhase 4 Code
Translation of the algorithm or flowchart to a programming language
Phase 5 Debug
Verified the code
Phase 6 Implementing the program
Phase 7 Maintenance of the program - 8Data that do not change their value during the development or execution of a program Numeric Represent the specific numeric value Alphanumeric Represent the specified lettersConstants
Numeric: 3, 100
Alphanumeric: “Home”, “Area” - 9Data that change or modify their value during the development or execution of a program It´s the space of memory where value is stored Numeric Store numeric data Alphanumeric Store letters, numbers and charactersVariables
Numeric: SUM = a + b
J = J + 1
Working variables: Results from operations
Counting variables: Count events
Accumulating variables: Sum values
Alphanumeric: A $ = “Spain”
Result = “Approved” - 10Classification of the types of operators
- 11Is defined as a set of ordered steps in a logic way Describe the solution of a problem, or for carrying out certain task They have begining and ending The steps are logically orderedAlgorithm
1. Start
2. Input A
3. Input B
4. AREA = BxA
5. Print AREA
6. End - 12Types of algorithms The steps are executed or described from the beginning to the end without skipping over any line Necessity to take decisions without some steps due to conditions, that carry us to answer true or false There are actions or steps that are repeated while or unit a condition is fulfilledSequential algorithm
Conditional algorithm
Cyclic algorithms - 13Graphical representation of an algorithm, is one of the programming tools that permit to visualize in general way to development of the solution of a problemFlowchart
- 14Blocks of the flowchar
- 15Not necessary to use a code of a programming language It is visualized the steps developSequential flowchart
- 16Used in partial way the code of a programming languageConditional flowchart
- 17Used frequently the code of a programming languageCyclic flowchart
