Algorithms and Programming Languages:
What is Algorithm
saq.png
The algorithm, in essence, is the flow of thought in completing a work which is poured in written form that can be understood by others. What is emphasized here is the flow of thought. A person's flow of thinking can be different from that of other people's minds to accomplish the same job with the same outcome.
In the learning algorithm, it is planned that the one who will carry out the first flow is the computer. Computers are designed to be able to execute commands given by humans. The command can be given in the form of a set of instructions called programs. The program is written in a language called programming language such as COBOL Language, Basic Language, Pascal Language, C Language, Java Language, and many other languages. Of the many programming languages, the instruction writing can be the same, almost the same, completely different, for the same purpose.
From the description above, can be understood that algorithms that we read from literature books or on the internet although one with the other can be no difference, but all closer to the ordinance of writing a programming language that the general form.
Each Algorithm must meet the following criteria:
  • The presence or absence of data entered
  • There is at least one output
  • Every instruction is clear and has only one meaning
  • Algorithm both as a whole and sub-programs when traced there must be a stop
  • Any instructions other than clear must also be executable, and also effective in the sense of having to produce something
In addition to criteria, the algorithm also has a domain :
  • Problem: motivation or reason to create algorithm
  • Algorithm: the procedure to solve the problem. Often one problem can be solved in more than one way (many possibilities).
  • Program: the formal representation of an algorithm by using a programming language that can be understood by the computer.
  • Process: activity runs the procedures in the algorithm.
The following example of the algorithm and pseudo code is written as below as the table below

Computer Graphics Project "Planet Orbit" Source Code with Glut OpenGL

Image
Hello there !!!  This time I will post a project in the past. It is about rotation and applied to make earth orbital with moon and sun. As reminder, for you who haven’t install glut you can download it in here and follow the instruction I uploaded too. You can download this orbital project in here too. The image above is the result of orbital project. Here is the source code for this project. #include <windows.h> #include <stdlib.h> #include <GL/glut.h> #include <math.h> void myinit() { glClearColor(0.0, 0.0, 0.0, 1.0); glColor3f(1.0, 0.0, 0.0); glMatrixMode(GL_PROJECTION); glLoadIdentity(); glOrtho(-400.0, 400.0, -400.0, 400.0,-400.0,400.0); glMatrixMode(GL_MODELVIEW); glShadeModel(GL_FLAT); glEnable(GL_DEPTH_TEST); } float putaransatu, putarandua = 0; typedef struct{ float x,y; } point2D_t; void drawDot(int x,int y){ glBegin(GL_POINTS); glVertex2i(x,y); glEnd(); } /*void bintang(void) { static int tick=0; static...

Quantization of Image Data Implementation in C#

Image
Introduction  This time we will share how to create an application to change the threshold value from black-and-white to the average value of the gray degree of all points and add textBox so that the user can change the threshold value according to the user's wishes. Besides that we also will add textBox to input quantization value. So the user can change the quantization as desired. Application Screenshoot A black-and-white image is an image that contains only black or white. Black is valued 0 and white is valued 255. To make the picture in black and white, the original color will be gray degree and each pixel will be compared with its threshold value. Normally, the black-and-white degree image has a 128 threshold value, so if the color value is less than 128, then the color is changed to 0 (black), and which is greater than or equal to 128 will be converted to 255 (white). Consider the example image below. Figure 1. The original image is predominantly dark When vi...

Computer Graphics Project "MINION" Source Code with Glut OpenGL

Image
Hello !!! This time I post about computer graphics again. And yes, I will share a project which mainly used rotation and a little bit morphing. You can download this project here ( Download here to download glut and follow the instruction ) .The character used in this project is well known. Well here’s the depiction of this project. Minion !!! The eyes will rotate. And it’s smile will move up and down which give you a creepy smile hahaha.  So here’s the source code for this project : #include <stdio.h> #include <math.h> #include <GL/glut.h> #ifndef M_PI #define M_PI 3.141592653589793 #endif typedef struct { float x; float y; } point2D_t; typedef struct { float r; float g; float b; } color_t; ////////////// OpenGL drawShape Functions ver 1 ///////////////// void setColor(float red,float green,float blue) { glColor3f(red, green, blue); } void setColor(color_t col) { glColor3f(col.r, col.g, col.b); } void drawDot(float x,float y) { ...
