1. List the fundamental data types along with their ANSI-stipulated minimum sizes. Why are these sizes not fixed by ANSI?

2. Even though the size of the fundamental data types may vary across systems, the char data type is always one byte wide. Explain.

3. Name at least three sources of data that are available to a program.

4. Spot the valid variable names in the list: (i) bit-rate, (ii) upload_speed, (iii) __width, (iv) a1, (v) 2017_month.

5. When does it make sense for a constant to be stored in a variable? How does #define differ from the const keyword?
