This semester we looked at three languages (C++, Java and Python). One common rule in all three class checklists (for C++, Java
Marysya12 [62]

Answer:

The languages C++, Java, Python are Object Oriented Programming languages. What this means is that we create classes and then instantiate those classes. In C++ and Java, we use the new operator to instantiate the classes. So, if we want to display some data when we try to print the instance just like we print the variables of data types like int, double, string etc, we need to define what we need to display. It is because, class are just like data types like int, double etc. But as they are defined by the developer according to his/her needs, so the developer has to define what to print when they are printed.

horrorfan [7]

Answer:

//Define class

public class Main {

 //define main method

 public static void main(String[] args)  

 {

   //declare and initialize the double type variable to 128

   double mexico = 128;

   //declare and initialize the double type variable to 323

   double us = 323;

   //declare and initialize the integer type variable to 0  

   int yr = 0;

   //set the while loop to check which is greater

   while (mexico < us)  

   {

     //increment in the variable by 1

     yr++;

     //initialize in the variables acc. to the percentage

     mexico *= 1.0101;

     us *= 0.9985;

   }

   //print the following results

   System.out.println("Population of the Mexico will be exceed the population U.S. in " + yr + " years");

   System.out.println("Population of the Mexico will be " + mexico + " million");

   System.out.println("and population of the U.S. will be " + us + " million");

 }

}

<u>Output</u>:

Population of the Mexico will be exceed the population U.S. in81 years

Population of the Mexico will be 288.88435953355025 million

and population of the U.S. will be 286.0198193927948 million

Explanation:

<u>Following are the description of the program</u>.

  • Firstly, we define the class 'Main' and inside it, we define the main method.
  • Then, declare two double data type variables which are 'mexico' and 'us' and initialize in it to 128 and 323.
  • Declare integer data type variable 'yr' and initialize in it to 0.
  • Set the while loop and pass the condition to check that the variable 'mexico' is less than the variable 'us' then, increment in the variable 'yr' by 1 and multiply the variables 'us' and 'mexico' by the following percentage.
  • Finally, print the following results with the message.

Many documents use a specific format for a person's name. Write a program whose input is: firstName middleName lastName, and who
never [62]

Answer:

Python Program:

if __name__ == '__main__':

   a = input("Enter Name: ")

   b = a.split()

   print(b[2] + ',' , b[0], b[1][0])

Explanation:

The input function will be used to prompt user to enter the name of the person. The person's name will be stored in variable a.

Let us assume that the user entered a name mentioned in the example, which is Pat Silly Doe, Now variable a = 'Pat Silly Doe'.

The function a.split() is used to split a string into a list. The splitting (by default) is done on the basis of white-space character. Therefore, a.split() will give a list

['Pat', 'Silly', 'Doe']

which will be later on stored in variable b.

We can use the subscript operator [] to access the values in a list. Suppose if we have a list a, then a[i] will give us ith element of a, if i < length of a.

Finally, we print the answer. b[2] will give us the last name of the person. We append a comma using '+' operator. b[0] will give us the first name. b[1] will give us the middle name, but since we only need one character from the middle name, we can use another subscript operator b[1][0] to give us the first character  of the middle name.

Note: Characters of strings can be accessed using subscript operator too.
