Practice: Fahrenheit

Converting temperature…

Converting Temperature

Write a C program that converts degrees Celsius to Fahrenheit, like so:

$ ./fahrenheit
C: 0
F: 32.0

Implementation Details

Create a file called fahrenheit.c. Your program must do the following:

• Accept as input a value in Celsius
• Output the equivalent temperature in Fahrenheit to exactly one decimal place.

Hints

• Don’t forget about truncation!
• If you don’t remember the conversion formula:

F = ((C * 9) / 5) + 32

• When using printf() to print a floating point number, you can specify how many decimal places to display. For example:

#include <stdio.h>

int main(void)
{
   float pi = 3.1415926535;
   printf("%.2f\n", pi);
}

The above code would output 3.14 because the %.2f specifies 2 decimal places in the float placeholder.

How to Test Your Code

Does your code work as prescribed when you input

• -1.00 (or any other negative numbers)?
• 0.00?
• 0.01 (or any other positive numbers)?

You can also execute the below to evaluate the correctness of your code using check50. But be sure to compile and test it yourself as well!
