Three types of expression have been introduced here;
- Arithmetic expressions are simple, but watch out for subtle type conversions. The
shorthand notations may save you a lot of typing.
- Comparison takes two numbers and produces a logical result. Comparisons are usually
found controlling if statements or loops.
- Logical connectors allow several comparisons to be combined into a single test. Lazy
evaluation can improve the efficiency of the program by reducing the amount of calculation
required.
C also provides bit manipulation operators. These are too specialised for the scope of
this course.
