Program 1- To check whether the inputed character is an alphabet or a digit

or a special symbol.

#include

#include

char char_is(char a);

void main()

{

clrscr();

char ch,ct;

printf("Enter a character= ");

ch=getchar();

ct=char_is(ch);

if(ct=='A')

printf("It is an Alphabet.");

else if(ct=='D')

printf("It is a Digit.");

else if(ct=='X')

printf("It is a Special Character.");

getch();

}

/* Function Declaration to determine character type*/

char char_is(char a)

{

if((a>='a' && a='A' && a='0'&&a

Program 2- To read a line of text and count the number of vowels,

consonants digits and blank spaces.
