Programming Concepts

Program code can be organized through the use of functions. What are the criteria on creating functions?

The C/C++ language has two different types of conditional statements (if-else and switch-case). What do you see as the benefits and drawbacks of each conditional statement and when and why would you use one over the other?

Write a C program (Use Miracle C compiler)

Write a C program that displays a title, "Currency Conversion," and then write the names of five currencies and their equivalents to the US dollar. The conversions are hard coded equations. Insert comments in the program to document the program internally. Attach a design flow chart (in MS Word, not Visio).
