Introduction to programming

Introduction to programming

1. Program

   • set of instrcctions written in a programming language can perform certain tasks in a quick and correct way

2. Programming lenguage

   • set of symbols that controls the pysical and logical behavior of a compter. permits to specify data

3. Programming

   • methodology to do programs. the code of the programs is written by proffesionals known as programmers
     • Stage 1
       • 1.Definition of the problem
         • 2. Analisys of the problem
           • 3. Design:
             • Algorithm flowchart test
           • Analysis of the problem
             • Input
               • Data the we have to enter for the solution of the problem
             • Outpt
               • Solution of the problem
             • Process
               • procedures where the input data are used to solve the problem
                 • Data types
                   • Constants
                     • Data that do not change their value during the development or execution of a program
                       • Numeric
                         • represent the specific numeric value
                       • Alphanuumeric
                         • represent the specified letters
                   • Variables
                     • Data that change or modify their value during the development or execution of a program; also it is the space of memory where values are stored
                       • Numeric
                         • store numeric data
                       • Alphanumeric
                         • store letters, numbers and secuencial characters
                   • Types of operators
                     • Arithmetic
                       • Comparision
                         • Logical
                         • Analysis of the problem
                           • Input
                             • Data the we have to enter for the solution of the problem
                           • Output
                             • solution of the problem
                           • Process
                             • procedures where the input data are used to solve the problem
     • Stage 2
       • 4. Debug
         • 5. Code
           • 6. Implementing program
             • 7. Maintenance of the program
