C++ Program to Convert Celsius to Fahrenheit

«
»
This C++ Program performs Celsius to Fahrenheit conversion. The program reads the temperature in Celsius, multiplies the temperature in Celsius by 9 / 5 and adds 32 to obtain temperature in Fahrenheit.

Here is source code of the C++ program which performs Celsius to Fahrenheit conversion. The C++ program is successfully compiled and run on a Linux system. The program output is also shown below.

  1. /*
  2.  * C++ program to perform celsius to fahrenheit conversion
  3.  */
  4. #include<iostream>
  5. using namespace std;
  6.  
  7. int main()
  8. {
  9.     float fahrenheit, celsius;
  10.  
  11.     cout << "Enter the temperature in Celsius : ";
  12.     cin >> celsius;
  13.     fahrenheit = (celsius * 9.0) / 5.0 + 32;
  14.     cout << "The temperature in Celsius    : " << celsius << endl;
  15.     cout << "The temperature in Fahrenheit : " << fahrenheit << endl;
  16.     return 0;
  17. }

$ g++ main.cpp
$ ./a.out
Enter the temperature in Celsius : -40
The temperature in Celsius    : -40
The temperature in Fahrenheit : -40
