Conditional Statements: if Execute code block 'a' if condition A is met, otherwise execute code block 'b'. This control flow is called a condisional statemant. Basic Example age = 20 if age >= 18: print("Adult") else: print("Minor") Multi-Condtiion Example score = 75 if score...
Namespaces in C++ prevent naming conflicts and enable controlled access between diffferent code sections. As projects grow larger, the likelihood of name collisions increases, especial when integrating third-party libraries that may define identical identifiers differently. Defining Namespaces names...
One-Dimensional Arrays An array is a fundamental container in Java designed to store multiple values of a single data type. Once initialized, its length is fixed, providing a high-performance way to manage ordered data. Static Initialization Static initialization is used when the exact values of the...
Python source files are typical saved using UTF-8 encoding to ensure proper handling of characters during storage and transmission. The print function sends data to the console. By default, print adds a newline character after the output, but this behavior can be modified using the end parameter. #...
fn greet_world() { println!("Hello, world!"); let german_greeting = "Grüß Gott!"; let japanese_greeting = "ハロー・ワールド"; let greetings = [german_greeting, japanese_greeting]; for greeting in greetings.iter() { println!("{}", greeting); } } fn main() { greet_world...
Switch Statements Purpose Primarily used for equality comparisons against multiple values. Syntax switch(variable) { case value1: // code block break; case value2: // code block break; default: // default code block break; } Key notes: Default block is optional Break statemants exit the switch block...
When everyone is busy posting photos on social media, there are always some people who are too handsome to have friends. This problem asks you to identify those who are too handsome to have friends. Input Format: The first line contains a positive integer ( N ) (≤100), the number of known friend cir...
Class References The fundamental reflection capability involves obtaining runtime references to Kotlin classes. To retrieve a reference to a statically known Kotlin class, use the class literal syntax: val customClass = MyClass::class Kotlin class references differ from Java class references. To obt...
List Comprehensions List comprehensions offer a compact and readable way to construct sequences. Instead of initializing an empty list and appending elements in a loop, you express the entire transformation in a single line. For example, generating squares of integers from 0 to 9: squares = [] for n...
Opening Files with the open() Function To open a file in Python, use the open() functon, which returns a file object. Specify the file path and mode. Common modes include 'r' for reading, 'w' for writing (overwrites existing content), and 'a' for appending. file_obj = open("example.txt", &...
