Can you tell me the reason behind output? It shows sololearn

Question

#include<stdio.h>
int main()
{
do{
printf("sololearn");
}while(5,3,0);
}

Answer 1

Jerry Hobby yes its not valid condition but if we will write any positive number or non zero numbers then its treat as a true like if i write like this
if(5) here 5 is non zero so it will be true and statement will be execute.
In case of a=(1,2,3) if we will print values of a it will print 3 right so same here do while loop execute atleast once so sololearn will be print once

Answer 2

That doesn't even compile. It doesn't show "sololearn" because it doesn't even run.

In case you edit the question, here is what I'm looking at now:
#includr<stdio.h>
int main()
{
printf("sololearn");
}while(5,3,0);
}

Here are the messages:
./Playground/file0.c:1:2: error: invalid preprocessing directive #includr; did you mean #include?

Why doesn't it compile?

Your while-loop condition is messed up. It needs to be an expression that can be evaluated to something representing true or false and "5,3,0" doesn't work.

It is "include" not "includr".

{} brackets are not balanced. You have more closing } than opening {.

A minor warning would be shown because your main function returns int but then you have no return statement.

What is the point of (5,3,0). That’s not a valid condition, logically.
