practice using printf() and scanf()
Assignment
Write a program that asks the user for the user's name and the user's height in inches. Your program then replies with the user's name and height in centimeters. A sample run of your program might look like this: (The user's response is in orange.)linux3[1]% gcc -Wall height.c -o height.out linux3[2]% ./height.out What is your name? Lancelot How tall are you in inches? 78 Hello, Lancelot. You are 198.120000 centimeters tall. linux3[3]%
Notes
- Please name your C program height.c
- You can use any of the programs we have seen in class as a starting point.
- Think about how many variables you might want for this program. What should their types be? int, double, ...?
- If you have extra time, consider the following
embellishments:
- Most people do not need to see their height with 6 digits after the decimal point (especially in centimeters). In printf(), you can use modifiers with %f to specify the precision. For example %8.3f, says to print a total of 8 characters (including the decimal point) and use 3 digits after the decimal point.
- Play around with the precision until you have a format that looks good to you.
- Suppose that you want to round the height to the nearest centimeter. E.g., you want to have 198.120000 reported as 198 and 198.621000 reported as 199. How can you do this?
Submitting the Program
For this assignment, you just submit your source code file,height.c (make sure you you this name).
To submit your project, type the following at the Unix prompt.
Note that the project name starts with uppercase
'H'.
