Write a program that prompts the user to enter the weight of a person in kilograms and outputs the equivalent weight in pounds (Note that 1 kilogram equals 2.2 pounds). Format your output with two decimal places.

Consider the following C++ program in which the statements are in the incorrect order.

Rearrange the statements so that it prompts the user to input the radius of a circle and outputs the area and circumference of the circle.

#include <iostream>
 
{
 
int main()
 
cout << "Enter the radius: ";
 
cin >> radius;
 
cout << endl;
 
double radius;
double area;
 
using namespace std;
 
return 0;
 
cout << "Area = " << area << endl;
 
area = PI * radius * radius;
 
circumference = 2 * PI * radius;
 
cout << "Circumference = " << circumference << endl;
 
const double PI = 3.14;
 
double circumference;
}

Consider the following program segment:

//include statement(s)
//using namespace statement
 
int main()
{
//variable declaration
 
//executable statements
 
//return statement
}

Write a C++ statement that includes the header file iostream.

Write a program that produces the following output:

CCCCCCCCC       ++              ++
CC              ++              ++
CC        ++++++++++++++  +++++++++++++++
CC        ++++++++++++++  +++++++++++++++
CC              ++              ++
CCCCCCCCC       ++              ++

Note: The letter C in the output must be uppercase.

Write a python program that prompts the user to enter a few details: fullname, age, job, country and salary which are going to be included in an html file. 

 In a python module, define two functions:

• 1. A function that finds the number of words contained in a text file. 
• 2. A function that finds the number of occurrences of a given word in a given file. 
• • In another file, use these functions by asking the user about the name of the file and the word he/she wants to search for.
