Q. Input a alphabet & print next one ?

THE OUTPUT WOULD BE

#include<stdio.h>
#include<conio.h>
  void main( )
  {   clrscr( );
  char ch;
  printf("Enter a Alphabet=");
  scanf("%c",&ch);
  if(ch>=65&&ch<=90)
  { ch=ch+1;
     printf("Next Alphabet=%c",ch);
  }
  else if(ch>=97&&ch<=122)
  { ch=ch+1;
     printf("Next Alphabet=%c",ch);
  }
  else
  printf("Wrong enter");
  getch( );
  }
