PRACTICAL-4

Aim of the practical:-

Write a program (WAP) to check the input from keyboard is a alphabet or number or a special character.

Header files used:-

#include <iostream.h>

#include <stdlib.h>

Conditional statements/Loops used:-

i.                   If– else –if ladder

Procedures followed:-

The user will be asked to press any key from the keyboard. Then the input will be compared with its range of ASCII values in successive if- else if () statements to identify which particular category it belongs to (alphabets/numbers/special characters).And finally the condition which it will satisfy will be shown as the output.

The details of range of ASCII values are:-

Characters	ASCII values
A… Z (Upper case alphabets)	65 to 90
a… z  (Lower case alphabets)	97 to 122
0…9   (Numbers)	48 to 57
