不喜欢if-else的有福了（bushi)

#include <bits/stdc++.h>

int main(){
    int a, b;
    scanf("%d", &a);
    b = !(a % 2) + (a > 4 && a <= 12);
    printf("%d %d %d %d", b == 2, !!b, b == 1, !b);
}

简简单单打个表

AC代码：

#include <bits/stdc++.h>
using namespace std;
inline int read(){
	register int x = 0;
	register bool f = 0;
	register char c = getchar();
	while(c < '0' || c > '9'){
		if(c == '-') f = 1;
		c = getchar();
	}
	while(c>='0'&&c<='9'){
		x = (x << 3) + (x << 1) + c - 48;
		c = getchar();
	}
	return f ? -x : x;
}
int a,b;
int main(){
	a = read();
	if(a % 2 == 0) b++;
	if(a > 4 && a <= 12) b++;
	if(b == 2) cout << "1 1 0 0";
	if(b == 1) cout << "0 1 1 0";
	if(b == 0) cout << "0 0 0 1";
    return 0;
}

#include<bits/stdc++.h> using namespace std; int main() { int x; cin>>x; if(x%20 && (x>4 && x<=12)) { cout<<1<<" "; } else { cout<<0<<" "; } if(x%20 || (x>4 && x<=12)) { cout<<1<<" "; } else { cout<<0<<" "; } if((x%2==0 && (x<=4 || x>12)) || (x%2!=0 && (x>4 && x<=12))) { cout<<1<<" "; } else { cout<<0<<" "; } if(x%2!=0 && (x<=4 || x>12)) { cout<<1<<" "; } else { cout<<0<<" "; } return 0; }
