## Problem statement

Given the temperature in Celsius, we have change it to Kelvin using the class and object approach.

Example:

Input:
Enter Temperature in Celsius: 45

Output:
Temperature in Kelvin : 318.15

## C++ code to convert the temperature from Celsius to Kelvin using the class and object approach

#include <iostream>
using namespace std;

// create a class
class CelsiusToKelvin {
// private data member
private:
float celsius;

// public functions
public:
// getTemperature() function to
// get the Temperature
void getTemperature() {
cout << "Enter Temperature in Celsius: ";
cin >> celsius;
}

// CToK() function to convert the temperature
double CToK() {
// initialising float type variables
// to perform operations
float kelvin;

kelvin = celsius + 273.15;

// returning converted temperature
return kelvin;
}
};

int main() {
// create a object
CelsiusToKelvin C;

// float type variable to store
// converted temperature
float temperature;

// function is called by the object
// to store the temperature
C.getTemperature();

// CToF() function to convert the temperature
temperature = C.CToK();

cout << "Temperature in Kelvin : " << temperature;

return 0;
}

### Output

Enter Temperature in Celsius: 23
Temperature in Kelvin : 296.15

### Explanation

In the above code, we have created a class CelsiusToKelvin, one float type data member celsius to store the temperature in celsius, and public member functions getTemperature() and CToK() to store and convert the given temperature.

In the main() function, we are creating an object C of class CelsiusToKelvin, reading the temperature by the user using the function getTemperature(), and finally calling the CToK() member function to convert the given temperature from celsius to kelvin. The CToK() function contains the logic to convert the given temperature from celsius to kelvin and printing the result.
