Paradigm	Procedural	Multi-Paradigm (Procedural, Object-Oriented, Generic)	Object-Oriented	Multi-Paradigm (Object-Oriented, Procedural, Functional)
Syntax Example	c #include <stdio.h> int main() { printf("Hello, World!\\n"); return 0; }	cpp #include <iostream> using namespace std; int main() { cout << "Hello, World!\\n"; return 0; }	java public class HelloWorld { public static void main(String[] args) { System.out.println("Hello, World!"); } }	python print("Hello, World!")
Input Method	c #include <stdio.h> int main() { int num; scanf("%d", &num); return 0; }	cpp #include <iostream> using namespace std; int main() { int num; cin >> num; return 0; }	java import java.util.Scanner; public class InputExample { public static void main(String[] args) { Scanner scanner = new Scanner(System.in); int num = scanner.nextInt(); } }	python num = int(input("Enter a number: "))
Output Method	c printf("Number: %d\\n", num);	cpp cout << "Number: " << num << endl;	java System.out.println("Number: " + num);	python print(f"Number: {num}")
