Advanced Programming & Software development:
What is python?
Python is a general purpose, dynamically typed high level language developed by “Guido Van Rossum” in the year 1991 at CWI in the Netherlands.
Data science with python:
What is data science?
Data science is about finding and exploring data in real world, and then using that knowledge to solve business problems.
Example
Customer prediction:
systems can be trained based on customer behaviour patterns to predict the likelihood of a customer buying a product.
Service planning:
Restaurants can predict how many customers will visit on a weekend and plan their food inventory to handle the demand.
Data Acquisition:
Web services.
Logs.
Databases.
API’s
Online depositories.
Machine learning basics:
Machine learning is a subset or a current application of AI it is based on the idea that we should be able to give machine the access to data and let them learn from themselves it's a subset of artificial intelligence that deals with the extraction of pattern from data set this means that the machine can not only find the rules for optimal behaviour but also can adapt to the changes in the world many of the algorithms involved have been known for decades centuries even thanks to the advances in the computer science and parallel computing they can now scale up to massive data volumes so this was about the machine learning part.
The main point of view of machine learning is:
Subset of AI techniques which use statistical methods to enable machines to improve with experience.
As you know we are living in a world of humans and machines humans have been evolving and learning from the past experience since millions of years in the other hand the era of machines and robots have just begun in today's void these machines or the robots are like they need to be programmed before they actually follow your instructions but what if the machine started to learn on their own and this is where machine learning comes into picture machine learning is the core of many futuristic technological advancement in our world today you can see various examples or implementation of machine learning around us such as Tesla’s self-driving car Apple Siri Sophia AI robot and many more are there.
Machine learning types:
Supervised.
Unsupervised.
Reinforcement.
What is Java?
In today's era, the internet and smartphones have become an integral part of our lives. We use our phones for almost all of our day to day tasks. Earlier, we used to shop at malls, queue up in front of banks and make our travel bookings at travel agencies. But now we can do all this in the comfort of our homes using smartphones. All of this is possible because of a high level programming language called java.Java is an object oriented programming language that is used in a distributed environment on the internet. It is a high level language that is easy to read and understand. Java is popularly used in Console, GUI, web, and mobile applications, game development and also to make embedded systems.
Apart from these, Java is also used to develop software for devices. It is used not only in computers and mobiles but even in electronic devices like televisions, washing machines, air conditioners, and so on.
Online forms, banking, and shopping are possible because of Java. Java is a computer based programming language invented by James Gosling and Sun microsystems in 1991. He had a single motto while creating the language, it was “Write once, Run Anywhere.” This meant that the code would have to be written only once, but it could be used anywhere. They named this language “Oak” because of the Oaktree outside Gosling’s office. Later, it was named to “Gree”, then to “Java Coffee” which was named after the coffee from Indonesia, and finally to “Java” in 1995.
- Basic structure of Java:
public class HelloWorld {
public static void main(String[] args) {
System.out.println("Hello, World!");
}
}
Public class hello world defines a class.
Main method is the entry point of any java application.
System. out. Println prints to the console.
Variables and data types:
int number = 10;
double price = 19.99;
char letter = 'A';
boolean isTrue = true;
String text = "Java";
Conditionals:
if (number > 5) {
System.out.println("Greater than 5");
} else {
System.out.println("5 or less");
}
Loops:
for (int i = 0; i < 5; i++) {
System.out.println("i = " + i);
}
while (number > 0) {
System.out.println(number);
number--;
}
Methods:
public static int add(int a, int b) {
return a + b;
}
Classes and objects:
class Dog {
String name;
void bark() {
System.out.println(name + " says woof!");
}
}
// Usage
Dog d = new Dog();
d.name = "Buddy";
d.bark();
What is C++?
C++ is the object oriented programming language. It is used for web development, game programming, operating system, GUI applications and data structures.
C++ supports both procedural and object oriented programming language.
It is developed by Bjarne stroustrup at bell laboratories of AT&T in the year of 1980’s in USA.
It is one of the most popular programming language for graphical applications.
C++ language is similar to C language.
In other words C++ is “general purpose”, “case sensitive” free from programming language that supports object oriented procedural and generic programming.
It is an imperative and compiled language.
Here’s a quick overview of the basic syntax of C++ with a simple example:
Basic structure:
#include <iostream> // Preprocessor directive
using namespace std; // Avoids writing std:: repeatedly
int main() { // Main function: entry point of a C++ program
cout << "Hello, world!" << endl; // Output statement
return 0; // Ends the program
}
Variables and data types:
int age = 25;
float height = 5.9;
char grade = 'A';
bool isPassed = true;
string name = "John";
Conditional statements:
if (age > 18) {
cout << "Adult";
} else {
cout << "Minor";
}
Loops:
for (int i = 0; i < 5; i++) {
cout << i << " ";
}
