c++ program to convert kelvin to fahrenheit

#include <iostream>
using namespace std;

int main() {
    float kelvin, fahrenheit;

    cout << "Enter temperature in Kelvin: ";
    cin >> kelvin;

    fahrenheit = (kelvin - 273.15) * 9/5 + 32;

    cout << "Temperature in Fahrenheit: " << fahrenheit;

    return 0;
}

Explanation:

  • The program starts by including the necessary header file iostream, which provides input/output stream functionalities.
  • The using namespace std; statement allows us to use the standard library without explicitly specifying the std namespace.
  • The main() function is the entry point of the program.
  • Two variables kelvin and fahrenheit are declared as float to store the temperature values.
  • The cout statement is used to display the prompt message asking the user to enter the temperature in Kelvin.
  • The cin statement reads the user input and stores it in the kelvin variable.
  • The conversion formula (kelvin - 273.15) * 9/5 + 32 is used to convert Kelvin to Fahrenheit and the result is stored in the fahrenheit variable.
  • The cout statement is used to display the temperature in Fahrenheit.
  • Finally, the return 0; statement is used to indicate the successful execution of the program.
