LIBRARY ROUTINES

LIBRARY ROUTINES

LIBRARY ROUTINES

• ​Procedure/Subroutine/Function

• Pre-written block of code that performs a specific task

• Stored in library and given names

• Designed to be used frequently.

• Using library routines make writing programs faster and easier as part of the work has already been done (and debugged).

LIBRARY ROUTINES

• ​DIV

• MOD

• RANDOM

• ROUND

​SYNTAX

​EXAMPLE:
Value3 <--- ROUND(6.97354, 2) returns 6.97

Value4 <--- RANDOM( ) returns 0.2

MAINTAINABLE PROGRAM

• ​Meaningful Identifier names for var,cons,array,procedures and functions

• Smaller task

• Comments

​A maintainable program is one that is easy to understand, modify, and debug over time.

SCENARIO

Write a pseudocode & python code to simulate a temperature conversion program. Your program should: -

• Prompt the user to enter a temperature in Celsius.

• Convert the temperature to Fahrenheit using the formula: F = (C * 9/5) + 32.

• Use the ROUND function to round the Fahrenheit temperature to two decimal places.

• Display the rounded Fahrenheit temperature.

• Use the MOD function to determine if the Fahrenheit temperature is an even or odd number. - Display whether the temperature is even or odd.
