Practice Problem

• Problem:01

In this challenge, write a program that takes in three arguments, a start temperature (in Celsius), an end temperature (in Celsius) and a step size. Print out a table that goes from the start temperature to the end temperature, in steps of the step size; you do not actually need to print the final end temperature if the step size does not exactly match. You should perform input validation: do not accept start temperatures less than a lower limit (which your code should specify as a constant) or higher than an upper limit (which your code should also specify). You should not allow a step size greater than the difference in temperatures. (This exercise was based on a problem from C Programming Language).   

Sample run:

  Please give in a lower limit, limit >= 0: 10
  Please give in a higher limit, 10 > limit <= 50000: 20
  Please give in a step, 0 < step <= 10: 4

  Celsius         Fahrenheit
  -------         ----------
  10.000000       50.000000
  14.000000       57.200000
  18.000000       64.400000

Line Count Programming Challenge 

Here's a simple help free challenge to get you started: write a program that takes a file as an argument and counts the total number of lines. Lines are defined as ending with a newline character. Program usage should be count filename.txt and the output should be the line count.

File Size Challenge

 In this challenge, given the name of a file, print out the size of the file, in bytes. If no file is given, provide a help string to the user that indicates how to use the program. You might need help with taking parameters via the command line or file I/O in C++ (if you want to solve this problem in C, you might be interested in this article on C file I/O).
