Write a C program to input a character, then check if the input character is digit, letter, or other character.

// CPP program to find type of input character

#include <iostream>

using namespace std;

void charCheck(char input_char)

{

// CHECKING FOR ALPHABET

if ((input_char >= 65 && input_char <= 90)

|| (input_char >= 97 && input_char <= 122))

cout << " Alphabet ";

// CHECKING FOR DIGITS

else if (input_char >= 48 && input_char <= 57)

cout << " Digit ";

// OTHERWISE SPECIAL CHARACTER

else

cout << " Special Character ";

}

// Driver Code

int main()

{

char input_char = '$';

charCheck(input_char);

return 0;

}
