3. Operators and Control Flow
In this chapter, you will learn about operators, control flow statements, and the C# preprocessor. Operators provide syntax for performing different calculations or actions appropriate for the operands within the calculation. Control flow statements provide the means for conditional logic within a program or looping over a section of code multiple times. After introducing the
if control flow statement, the chapter looks at the concept of Boolean expressions, which are embedded within many control flow statements. Included is mention of how integers cannot be converted (even explicitly) to
bool and the advantages of this restriction. The chapter ends with a discussion of the C# preprocessor directives.
