char variable

[priyanshm]

how do i use a char variable in an if statement

for eg.

#include<iostream.h>
#include<conio.h>
void main()
{
clrscr();
char a;
cin>>a;

after this I have to check whether the character is a digit or a character.
i havent been taught arrays and i cannot use #include<ctype.h>

Please tell me how to use the char variable in an if statement.
Thank you in advance.

the character a is represented as 'a', which just translates into the integer value 97.

if (a >= 'a' && a <= 'z') //if the char in variable a is between lowercase a and lowercase z 

you can do the same with '0' and '9', 'A' and 'Z', etc
