#include <iostream>
using namespace std;

int a,b;

   int main()
{
    cin >>a,b;
    if (a%2==0,b%2==0)(a%2==1,b%2==1),
        cout <<"yes"<<endl;
    else
        cout<<"no"<<endl;
    return 0;
}
我其实想要弄一个a，b是否同奇偶的，可就是不行，请求帮助！

#include <iostream>
using namespace std;

int main()
{
    int a, b;
    cin >> a >> b;
    if( (a%2==0 && b%2==0) || (a%2==1 && b%2==1) )
        cout << "yes" << endl;
    else
        cout << "no" << endl;
    return 0;
}

#include <iostream>
using namespace std;

int main( void )
{
    int a, b;
    cin >> a >> b;
    cout << (a%2==b%2?"yes":"no") << endl;
}

谢谢

哪来的内容 搞得这么复杂

if(a%2!=b%2)
