C++ Program to Convert a Range of Temperature in Celsius scale to Fahrenheit scale and Kelvin scale using ‘for’ loop and ‘while’ loop

AIM

Write and execute a C++ program to convert a range of temperature in Celsius scale to Fahrenheit scale and Kelvin scale using ‘for’ loop and ‘while’ loop. Do the conversions from 10⁰C to 30⁰C with an interval of 2⁰C.

ALGORITHM

Step 1.               Start

Step 2.               Declare variables  ctemp,ftemp and ktemp.

Step 3.               Write “Celcius”, “Fahrenheit” and “Kelvin” with proper spacing.

Step 4.               Repeat the steps with ctemp=10 till ctemp=30.

Step 5.               Fahrenheit,  ftemp=(ctemp*1.8)+32

      Kelvin, ktemp=(ctemp+273.15)

      ctemp=ctemp+2

Step 6.               Write ctemp, ftemp, ktemp.

Step 7.               Stop.

PROGRAM

1.       Using ‘for’ loop

#include<iostream>

#include<iomanip>    // for setw()

using namespace std;

int main()

{

float ctemp,ftemp,ktemp;

cout<<"\nCelcius"<<setw(20)<< "Fahrenheit"<<setw(20)<< "Kelvin \n";

for(ctemp=10;ctemp<=30;ctemp=ctemp+2)

{

ftemp=(ctemp*1.8)+32;

ktemp=(ctemp+273.15);

cout<<"\n\n"<<ctemp<<setw(20)<<ftemp<<setw(23)<<ktemp;

}

return(0);

}

2.       Using ‘while’ loop

#include<iostream>

#include<iomanip>    // for setw()

using namespace std;

int main()

{

float ctemp=10,ftemp,ktemp;

cout<<"\nCelcius"<<setw(20)<< "Fahrenheit"<<setw(20)<< "Kelvin \n";

while(ctemp<=30)

{

ftemp=(ctemp*1.8)+32;

ktemp=(ctemp+273.15);

cout<<"\n\n"<<ctemp<<setw(20)<<ftemp<<setw(23)<<ktemp;

ctemp=ctemp+2;

}

return(0);

}
