C in CS1010

Banned in CS1010

• The ++ and -- operators

  Use i += 1 or i -= 1 instead.

• Skipping of curly braces for single statement conditional or loop body

  Always use {} even if the conditional or loop body contains only a single statement.

• Nested conditional operator ?:

  Use nested if-else loop

• Global variables

  Declare the variables as local, automatic variables, and pass them around.

• Using int and short

  Always use long, which is guaranteed to be at least 32 bits. Exception: If a function from a C library calls for the use of int and offers no long alternative, then we have to use int.

• The type float

  Always use double

• Using integer values for true/false

  Use the bool type, and the values true and false

• goto

  Use combinations of conditionals and loops

Discouraged in CS1010
