To take sentence as a input in c++

I am trying to take the input of the two sentences one after the other,but while printing it is printing a blank space and in the next line it is printing the first sentence and the loop is exiting.

Here is my code:

int main() {

char b[100000];
char c[100000];
int t;
cin>>t;
while(t--)
{
    cin.getline(b,100000);
    cin.getline(c,100000);
    cout<<b<<"\n"<<c<<"\n";
}}

The input:

1

run run

good sentence

The output:

Blankspace

run run
