WAP to input an alphabet in uppercase or in lowercase. Display the next alphabet accordingly.(i.e. 'a' follows 'b',......'z' follows 'a').

Here are some tips for computer applications.
If you find this incomplete please add up in the comments!


Do all the programs of the textbook prescribed by your school and learn the theory part cover to cover.
 
Some important programs which may turn up -
Sorting & Searching (All 4 algos)
Programs that calculate ticket cost or fare according to a table.
Programs involving usage of constructors.
Involving the design of a class with global/instance variables.
Function overloading
Patterns and Series. (Practice as much as you can because the board can give any of those)
Lastly, some trivial questions like primality testing, factorization, etc.
 
Study smart instead of studying hard by doing similar programs and not wandering out of scope!
 
All the best. :)
