Types of Function

A function is a process or task that does some operation in the program. Some programming languages may contain built-in functions for certain commonly used tasks. Most programming languages also support user-defined functions, which means a user can write their own function to perform some operation. There are some libraries or header files that contain built-in functions for performing certain tasks.

1. Consider the following statements: DATAENDFLAG is off; ERROR equals 0; and SUM is less than 1024. Express the following sentences in symbolic notation: (i) DATAENDFLAG is off, ERROR equals 0, and SUM is less than 1024. (ii) (iii) (iv) DATAENDFLAG is off but ERROR is not equal to 0. DATAENDFLAG is off; however, ERROR is not 0 or SUM is greater than or equal to 1024. Either DATAENDFLAG is on or it is not the case that both ERROR equals 0 and SUM is less than 1024. (v) If DATAENDFLAG is off and SUM is less than 1024, then ERROR equals 0.
