Question: State which of the following are true and which are false. If a statement is false, explain why.
a) Experience has shown that the most difficult part of solving a problem on a computer is producing a working C program.
b) A sentinel value must be a value that cannot be confused with a legitimate data value.
c) Flow lines indicate the actions to be performed.
d) Conditions written inside decision symbols always contain arithmetic operators (i.e., +, -, *, /, and %). e) In top-down, stepwise refinement, each refinement is a complete representation of the algorithm. For Exercises 3.16-3.20, perform each of these steps:
1. Read the problem statement.
2. Formulate the algorithm using pseudocode and top-down, stepwise refinement.
3. Write a C program.
4. Test, debug and execute the C program.
