This Post Contains A Mini Project :~ C Program To Perform Various Operations On Strings. [Such As : Find Length, Copy, Reverse, Palindrome, Concatenation, Sub-string] With Correct Source Code, Algorithm & Output. This Program Is Written, Compiled & Executed At Turbo C/C++3.0 Compiler & Will Help You To Understand The Concept Of 'String Operations', 'Character Arrays', 'Functions', 'Menu Driven Concept' From C++ Language. It Is A Well-Structured Program With Proper Comments Which Provides Step-By-Step Description Of Various Features Of The Language In A Simple & Easy-To-Understand Way.
# Note : You Can Simply Copy-Paste The Following Program Or Code Into Compiler For Direct Result.
