C++ :

#include<bits/stdc++.h>
using namespace std;
int main(){
	int n;
	cin>>n;
	if(n>0)cout<<n<<">0"<<endl;
	else if(n<0)cout<<n<<"<0"<<endl;
	else cout<<n<<"="<<"0"<<endl;
	return 0;
}

Java :

import java.util.Scanner;

public class Main {

	public static void main(String[] args) {
		// TODO Auto-generated method stub
		Scanner sc = new Scanner(System.in);
		int n = sc.nextInt();
		if(n > 0){
			System.out.println(n + ">" + 0);
		}else if(n == 0){
			System.out.println(n + "=" + 0);
		}else if(n < 0){
			System.out.println(n + "<" + 0);
		}
	}

}

Python :

a=int(input())
if a<0:
    print(str(a)+"<0")
elif a>0:
    print(str(a)+">0")
elif a==0:
    print(str(a)+"=0")
