Write a C program to print character and digit.

#include <stdio.h>
#include <conio.h>
  main()
{
  char ch;
  clrscr();
  printf("\n Enter any character ");
  scanf("\n %c",&ch);

  if(ch>=65&&ch<=90)
{
  printf("\n Character entered is Capital letter");
}
  else
{
  if(ch>=97&&ch<=122)
{
  printf("\n Character entered is small letter");
}
  else
{
  if(ch>=48&&ch<=57)
{
  printf("\n character is digit");
}
  else
{
  printf("Character is special symbols");
}
}
}
  return(0);
}

 output:-
 enter the any character =50

 character is digit
 enter the character  =120
 character is small letter 
 

Write a c program to prints an ascii numbers.

#include <stdio.h>
#include <conio.h>
#define and &&
  main()
{
  int num=48;
  clrscr();
  while(num>=48&&num<=60)
{
  printf("\n ascii= %d character = %c",num,num);
  num++;
}
  return(0);
}

output:-
 ascii =48 character =0

 ascii =49 character =1

 ascii =50 character =2

 ascii =51 character =3

 ascii =52 character =4

 ascii =53 character =5

 ascii =54 character =6

 ascii =55 character =7

 ascii =56 character =8

 ascii =57 character =9

 ascii =58 character = :

 ascii =59 character = ;

 ascii =60 character = <
