write a modular program to read four characters from the keyboard and determine the greatest character in terms of the ordering of the alphabets (a, b,..., x, y, z).

anonymous · Answer

you can have functions read(), cmp() and write.Read function would read the input from standard input.Compare function would be an O(N) procedure which will find the greatest character.And write would be a function which is called after compare and just writes the greatest character.

You haven't specified the language but I'll assume a 'C'-like one anyway. Pseudo-code might look like:

Get all four inputs
Call isGreatest, sending it all four characters
Return the greatest character

The isGreatest function will need to compare each of the characters to determine which is the greater. Using a variable to hold the greatest of each comparison will probably help. This is the fun part of learning to code: coming up with the algorthm :)
