Can we perform xor operation on this ? (xor operation on strings)

#1

#include
using namespace std;
int main() {
int t;
cin>>t;
while(t–)
{
string a,b,c="";
cin>>a>>b;
int n = a.length();
for(int i = 0 ; i<n;i++)
{
if (a[i] == b[i])
c += “0”;
else
c += “1”;
}
cout<<c<<endl;
}
return 0;
}

@aditya12679,
No, xor operator(^) requires integer arguments.
