C++ Streams Should Not create New Line

Question

i try to make program that write timestamp to file with c++ here is my code :

#include <time.h>
#include <iostream>
#include <unistd.h>
#include <fstream>
using namespace std;
int main()
{
    fstream outfile;
    outfile.open("time.txt",ios::out|ios::app);
    string savetime;
    for(;;){
        time_t t = time(NULL);
        savetime=asctime(localtime(&t));
        cout<<savetime;
        outfile << savetime << endl;
        sleep(1);
    }
    
}

result of this code is

Sun Dec 06 01:28:17 2020

Sun Dec 06 01:28:18 2020

Sun Dec 06 01:28:19 2020

Sun Dec 06 01:28:20 2020

it has new line every lines. i have try to remove endl at outfile << savetime << endl; to remove new lines but file wont save new timestamp. my goal is to make output like this

Sun Dec 06 01:28:17 2020
Sun Dec 06 01:28:18 2020
Sun Dec 06 01:28:19 2020
Sun Dec 06 01:28:20 2020

thanks in advance.

#include <iostream>
#include <fstream>
#include <ctime>
#include <unistd.h>
using namespace std;
int main()
{
    fstream outfile;
    outfile.open("time.txt",ios::out|ios::app);
    char savetime[100];
    for(;;){
        time_t t = time(NULL);
        strftime(savetime, sizeof(savetime), "%A %c", localtime(&t));
        cout<<savetime;
        outfile << savetime<<endl;
        sleep(1);
    }
}

thanks to user4581301

from savetime=asctime(localtime(&t)); to strftime(savetime, sizeof(savetime), "%A %c", localtime(&t));
