Title description

Determine whether a positive integer is two digits (that is, greater than or equal to 10 and less than or equal to 99).

Mr. Garlic: It's very simple, come and pass it!

Input format

Ideas

It feels like there is nothing to say, just to judge whether a number is a two-digit number.

C language code:

#include<stdio.h>
int main()
{
    
    
	int n;
	scanf("%d", &n);
	if(n / 100 == 0 && n / 10 != 0) printf("1");
	else printf("0");
	return 0;
}

C++ code:

#include<bits/stdc++.h>
using namespace std;
int main()
{
    
    
	int n;
	while(cin >> n)
		if(n >= 10 && n < 100) cout << "1" << endl;
		else cout << "0" << endl;
	return 0;
}
