What does the following program output?

#include

#include

using namespace std;

void outodd$()\{$

for $($int i $=1,$ i $<100$; i$+=2)$

cout $<<$ i $<<$ endl;

$\}$

void outeven$()\{$

for $($int i $=2$; i $<101$; i$+=2)$

cout $<<$ i $<<$ endl;

$\}$

int main$()\{$

thread t$1($outodd$)$;

thread t$2($outeven$)$;

t$1.$join$()$;

t$2.$join$()$;

$\}$

choose the correct answer

The odd numbers and even numbers are mixed in an unpredictable manner.

The odd and even umbers alternate, because the threads take turns

All the odd numbers $1-99,$ followed by all the even numbers $2-100($always$).$ Because the odd thread is started first

The program crashes, because the threads conflict with each other
