Procedures, Parameters & Sub-Programs
In any modern programming language, procedures play a vital role in the construction of any new software. These days, procedures are used instead of the old constructs of GOTO and GOSUB, which have since become obsolete.
Procedures provide a number of important features for the modern software engineer:-
Programs are easier to write. Procedures save a large amount of time during software development as the programmer only needs to code a procedure once, but can …showed first 75 words of 1021 total…
