{checks whether the input character is uppercase, lowercase, or digits}

Declaration

character : char

Description

read (character)

if (character >= 25 And character <= 90) then

write (Uppercase)

else if (character >= 97 And character <= 122) then

else if (character >= 47 And character <= 57) then

write (Digit)

Program C++

#include <iostream>
using namespace std;

class character_check{
	friend ostream& operator<<(ostream&, character_check&);
	friend istream& operator>>(istream&, character_check&);

	public :
		char character;
		void process();	
};

istream& operator>>(istream& in, character_check& input){
	cout<<"input character : ";
	in>>input.character;
	return in;
}

void character_check::process(){
	if (character >= 65 && character <= 90){
		cout<<"Uppercase";
	}else if (character >= 97 && character <= 122){
		cout<<"Lowercase";
	}else if (character >= 47 && character <= 57){
		cout<<"Digits";
	}
}

ostream& operator << (ostream& out, character_check& outp){
	outp.process();
	return out;
}

int main(){
	character_check x;
	
	cin>>x;
	cout<<x;

}
