This zyLab activity prepares a student for a full programming assignment. Warm up exercises are typically simpler and worth fewer points than a full programming assignment, and are well-suited for an in-person scheduled lab meeting or as self-practice. For each of the following steps, end the program's output with a newline.
(1) Write a program that outputs the following. (1 pt)
(2) Update to output the following. (1 pt)
Hello world!
How are you?
(3) Finally, update to output the following. (1 pt)
Hello world!
How are you?
(I'm fine).
LAB ACTIVITY
1.14.1: LAB: Warm up: Hello world
#include
int main(void) {
/* Type your code here. */
return 0;
}

Following are the code to the given points:

#include <iostream>//header file

using namespace std;

int main()//defining main method

{

   cout<<"Hello World!"<<endl;//print message for code 1

   cout<<"Hello world!\nHow are you?"<<endl;//print message for code 2

   cout<<"Hello world!\nHow are you? \n \t (I'm fine).";//print message for code 3

   return 0;

}

Output:

Please find the attached file.

Explanation:

In the given code, inside the main method, three print statement is used, that prints the given message which is defined in the question, for the printing of the message we use "\n, endl, and \t".

In which the "\n and endl" both are used in C++, to break the line into a new-line, and "\t" is used for providing a tab space.
