About Java Programming Language
Java, created by James Gosling in the mid-'90s, is a versatile and platform-agnostic programming language. It is specifically intended to prioritize portability, making it well-suited for a wide variety of applications. The primary advantage of Java is its object-oriented design, which facilitates the structuring of code through the use of classes and objects. The Java Virtual Machine (JVM) guarantees the smooth execution of Java programs across many platforms.

Taking Inputs in Java (stdin) using Scanner class
In Java, the Scanner class is a versatile tool for reading input from the standard input stream (System.in). It allows you to interactively take user inputs during the execution of your program. Here's a simple example demonstrating how to use the Scanner class to read an integer from the user:
import java.util.Scanner;
public class InputExample {
public static void main(String[] args) {
// Creating a Scanner object to read from the standard input
Scanner scanner = new Scanner(System.in);
// Prompting the user to enter an integer
System.out.print("Enter an integer: ");
// Reading the entered integer
int userInteger = scanner.nextInt();
// Displaying the entered integer
System.out.println("You entered: " + userInteger);
// Closing the Scanner to avoid resource leaks
scanner.close();
}
}
In this example, we create a Scanner object, prompt the user to enter an integer, read the input, and then display the entered integer.
Printing Output in Java (stdout)
Printing output in Java is commonly done using the System.out.println() method. This method prints the specified message to the standard output stream (System.out), typically the console. Here's a basic example:
public class OutputExample {
public static void main(String[] args) {
// Printing a simple message to the console
System.out.println("Hello, Java Output!");
// Printing variables along with text
int x = 5;
double y = 3.14;
System.out.println("The value of x is: " + x);
System.out.println("The value of y is: " + y);
// Formatting output using printf
String name = "John";
int age = 25;
System.out.printf("Name: %s, Age: %d%n", name, age);
}
}
In this example, we use System.out.println() to print messages to the console. Additionally, the printf method is used for formatted output, allowing you to specify placeholders for variables within the formatted string.
These basic input and output operations serve as the foundation for interactive and informative Java programs. Experiment with variations and explore more advanced features as you progress in your Java programming journey.
About C Programming Language
C, born in the early 1970s, stands out as a powerful procedural programming language crafted by Dennis Ritchie at Bell Labs. Over the years, it has proven itself as a cornerstone in the creation of diverse software systems. Renowned for its efficiency and the ability to directly interact with memory, C frequently becomes the preferred language for tasks such as system programming and embedded systems. Its concise syntax enables developers to engage in low-level manipulation, providing them with a robust and versatile tool.

Taking Inputs in C (stdin)
In the realm of C programming, we often call the standard input 'stdin.' To capture user inputs while your program is running, the scanf function comes into play. Let's explore a straightforward example that illustrates how to receive an integer input from the user:
#include <stdio.h>
int main() {
// Declare a variable to store user input
int userInteger;
// Prompt the user to enter an integer
printf("Enter an integer: ");
// Read the entered integer from the user
scanf("%d", &userInteger);
// Display the entered integer
printf("You entered: %d\n", userInteger);
return 0;
}
In this example, the scanf function is used to read an integer (%d) from the standard input. The entered value is then displayed to the user.
Printing Output in C (stdout)
Printing output in C is commonly achieved using the printf function. It allows you to display messages and values to the standard output, usually the console. Here's a basic example illustrating output in C:
#include <stdio.h>
int main() {
// Print a simple message to the console
printf("Hello, C Output!\n");
// Print variables along with text
int x = 5;
double y = 3.14;
printf("The value of x is: %d\n", x);
printf("The value of y is: %f\n", y);
// Formatting output using printf
char name[] = "John";
int age = 25;
printf("Name: %s, Age: %d\n", name, age);
return 0;
}
In this example, we utilize the printf function to display messages and values on the console. It comes with handy format specifiers like %d, %f, %s, %n, etc., allowing precise control over the output formatting.
These basic input and output operations play a vital role in crafting interactive and informative C programs. As you progress in your journey of C programming, don't hesitate to explore different variations and advanced features to elevate your skills.
About C++ Programming Language
C++ was conceptualized by Bjarne Stroustrup in the late 1970s as an expansion of the C programming language. It has object-oriented programming (OOP) characteristics, rendering it adaptable for many applications. C++ amalgamates the computational effectiveness of C with the principles of Object-Oriented Programming (OOP), allowing programmers to structure code using classes and objects. The flexibility of the software accommodates both low-level system programming and high-level application development.

Taking Inputs in C++ (stdin)
In C++ programming, the standard input is often referred to as cin. It allows you to read user inputs during the execution of your program. Here's a simple example demonstrating how to take an integer input from the user:
#include <iostream>
int main() {
// Declare a variable to store user input
int userInteger;
// Prompt the user to enter an integer
std::cout << "Enter an integer: ";
// Read the entered integer from the user
std::cin >> userInteger;
// Display the entered integer
std::cout << "You entered: " << userInteger << std::endl;
return 0;
}
In this example, the std::cin stream is used to read an integer from the standard input. The entered value is then displayed to the user using std::cout.
Printing Output in C++ (stdout)
Printing output in C++ is commonly achieved using the std::cout stream. It allows you to display messages and values to the standard output, usually the console. Here's a basic example illustrating output in C++:
#include <iostream>
int main() {
// Print a simple message to the console
std::cout << "Hello, C++ Output!" << std::endl;
// Print variables along with text
int x = 5;
double y = 3.14;
std::cout << "The value of x is: " << x << std::endl;
std::cout << "The value of y is: " << y << std::endl;
// Formatting output using std::cout
std::string name = "John";
int age = 25;
std::cout << "Name: " << name << ", Age: " << age << std::endl;
return 0;
}
In this example, the std::cout function is utilized to display messages and values on the console. The programming language supports a wide range of data types and provides the ability to manipulate the appearance of the output.
These core input and output procedures are crucial for creating engaging and informative C++ programs. While delving into the realm of C++ programming, endeavor to test out several iterations and sophisticated functionalities in order to augment your proficiency.
