A local variable is a type of variable declared within programming block or subroutines. It can only be used only inside that subroutine or code block in which they were declared. The local variable exists until the block of the function is in under execution. After that, it will be destroyed automatically.

Global variables are defined outside of a subroutine or function. The global variable will hold its value throughout the lifetime of a program. They can be accessed within any function defined for the program.

Your school has a document enlisting names of school students who have pass this year and taken admission in further courses. You have to edit the documents with the following changes: a) Find the word ‘utilitarian‘ and replace it with the word ‘pragmatic’ (Take care not to replace the word utilitarianism). b) The word college as it occurs in the text should be capitalize. Replace the word college with the correct capitalization i.e with College throughout the text using the appropriate option.
