Why is it printing t-1 line in output?

1 


#include <iostream>
#include <string.h>
#include <bits/stdc++.h>
#include <cstring>
using namespace std;

int main() 
{
	int t;
	cin>>t;
	while(t--)
	{
	 string str;
	 getline(cin,str);
	 int n=str.size();
	 char ch[n+1];
     strcpy(ch,str.c_str());
	 cout<<ch<<endl;
	}
	
	return 0;
}

What test input are you using?

Edit:

When using getline after reading an int, you need to skip the remainder of the line after the int:

#include <iostream>
#include <string.h>
#include <bits/stdc++.h>
#include <cstring>
using namespace std;

int main() 
{
    int t;
    cin>>t;
    cin.ignore(std::numeric_limits<streamsize>::max(), '\n');
    while(t--)
    {
        string str;
        getline(cin,str);
        int n=str.size();
        char ch[n+1];
        strcpy(ch,str.c_str());
        cout<<ch<<endl;
    }

    return 0;
}
