C++ Primer Plus Chapter 2 Exercise 4

c plus plusExercise 4 is slightly more involving, but provides all the information we need to convert temperatures.

4. Write a program that has main() call a user-defined function that takes a Celsius temperature
value as an argument and then returns the equivalent Fahrenheit value. The program
should request the Celsius value as input from the user and display the result, as
shown in the following code:
Please enter a Celsius value: 20
20 degrees Celsius is 68 degrees Fahrenheit.
For reference, here is the formula for making the conversion:
Fahrenheit = 1.8 × degrees Celsius + 32.0

 #include <iostream>

using namespace std;

float convert(float);
float celsius;

int main()
cout << "Please enter a celsius temperature: ";
cin >> celsius;

cout << celsius << " degrees celsius is " << convert(celsius) << " degrees fahrenheit" << endl;

return 0;

float convert(float celsius)
return (celsius * 1.8) + 32.0;
