Question :-

1: Find the cube of a number using Function.

2: Reverse a number n using Function, Constraints: -5000<=n<=5000

3: There are three numbers a,b,c. Put the value of a into b, put value of b into c and put value of c into a. Do it using Function.

4: Print “Hello Coder Army” n times using Function.

In the previous class we knew what its function was. In this class we will know the type of function and different return types they have.

Java: in java we cannot define function outside the class.
Parameterized Functions: Functions that accept parameters.
void printMessage(String message) {
System.out.println(message);
}

Non-parameterized Functions: Functions that do not accept any parameters.
void greet() {
System.out.println("Hello!");
}

Return Type Functions: Functions that return a value.
int add(int a, int b) {
return a + b;
}

Void Functions: Functions that do not return any value.
void greet() {
System.out.println("Hello!");
}

Python:
Parameterized Functions: Functions that accept parameters.
def greet(name):
print("Hello,", name)

Non-parameterized Functions: Functions that do not accept any parameters.
def greet():
print("Hello!")

Return Type Functions: Functions that return a value.
def add(a, b):
return a + b

Void Functions: In Python, all functions return None by default if no explicit return statement is provided.

C++:
Parameterized Functions: Functions that accept parameters.
void printMessage(string message) {
cout << message << endl;
}

Non-parameterized Functions: Functions that do not accept any parameters.
void greet() {
cout << "Hello!" << endl;
}

Return Type Functions: Functions that return a value.
int add(int a, int b) {
return a + b;
}

Void Functions: Functions that do not return any value.
void greet() {
cout << "Hello!" << endl;
}

These are the basic types of functions commonly used in Java, Python, and C++. Depending on the requirements of your program, you can choose the appropriate type of function to use.

Feel free to reshare this post to enhance awareness and understanding of these fundamental concepts.
