通过代码：

#include<iostream>
using namespace std;

int main()
{
long long *a,*b,*c;
int n;
cin>>n;
a=new long long [n];
b=new long long [n];
c=new long long [n];

for(int i=0;i<n;i++)
{
cin>>a[i]>>b[i]>>c[i];
if(a[i]+b[i]>c[i])
{
cout<<"Case #"<<i+1<<": true"<<endl;
}
else
{
cout<<"Case #"<<i+1<<": false"<<endl;
}
}

return 0;
}
