Answer:

#read value of name

name=input("Enter name:")

#find and ptint the last character of the string

print("last character of string is:",name[-1])

Explanation:

Read a string from user and assign it to variable "name".Find its last character as "name[-1]". Since name is character array,so name[-1] will give the last character of the array.

Output:

Enter name:Smith                                                                                                          

last character of string is: h

Define Class in C++. Briefly discuss.
lesya [120]

Answer:

Class are the collection of variable and member function.

Class are the blueprint of an object.

Explanation:

Following are the points regarding class in c++

1.In C++ class is an user defined datatype..

2.Classes are the collection of variable and function in c++.

3.To access the property of class we can create object of that class

4.We can use following syntax to declared any class in c++

class classname

{

accessmodifier:

//statement and function

};

main()

{

classname objectname;

}

implementation of class in c++

#include<iostream>

class test // class declaration

{

public: // access modifier

void fun3() // Method definition

{

cout<<" hello :";

}

};

void main() // main function

{

test ob;// creating object

ob.fun3(); // calling function

}

In this program we declared a class "test " in class test. We giving public access modifier .The public access modifier define that variable and function are accessible outside the class and in main method we create the object ob which call the function fun3().

Output:hello :

What the repeal of online privacy protections means for you?
kvv77 [185]
Online Privacy is well, our privacy while on the internet. If they have repealed that, then we have no privacy while on the internet. I feel like now a days there is no privacy at all anywhere. Everywhere you go, there are cameras watching you. So for them to take away online privacy is pretty messed up.
