It should be None of these as there will be a lexical error
#include<stdio.h>
int main()
{
in/* hhehr*/t t1;
}
Tried this code on the compiler here is what I get
:~$ gcc t1.c
t1.c: In function ‘main’:
t1.c:4:1: error: unknown type name ‘in’
in/* hhehr*/t t1;
^
t1.c:4:15: error: expected ‘=’, ‘,’, ‘;’, ‘asm’ or ‘__attribute__’ before ‘t1’
in/* hhehr*/t t1;
^
Clearly it shows lexical error
