noob help if /else

iam creating a program that the user will enter (upper/lower case) from A-H or (a-h)
how can i do that with an if statement this is what i did. but is not working

Code:

---

#include<stdio.h>
#include<conio.h>
#include<stdlib.h>


int main ()
{

      system("cls");
      float a;
      scanf("\n&#37;f",&a);
      if((a==A)||(a==H)&&(a==a)||(a==h));
      {   
          printf("hi");
      }
     
      else

      {
          printf("hello");
      }
 
      getch();
}

Firstly, declare it as

Code:

---

char c

---

not float a

You are just inviting trouble there.

Code:

---

if (((c >= 'A') && (c <= 'H')) || ((c >= 'a') && (c <= 'h'))) {

---

What that does is get an ASCII comparison

Also...

You are scanning it in wrong.

If it's a character, it should be %c not %f.

Also, use getchar() instead of scanf
