Expression? True(1):false(0)
In false condition it's always value is 0.
We don't modify it,
If can't assign the value n=1 in false condition.
In false condition it's always value is 0.
We don't modify it,
If can't assign the value n=1 in false condition.

In turbo c this prog gives error: "L-value required".
While in dev c++ its executes successfully and gives the o/p as: No

In grouping is required otherwise error as Lvalue required.
y == ? (n=0):(n=1);
Here you will not get error friends.
y == ? (n=0):(n=1);
Here you will not get error friends.

Here the ternary operator is used so that it will need the left-hand side value like in the form of ternary syntax.

I don't think there is an error in the program. It give No as output when executed on Dev C++;.

The syntax y == 1 ? n=0 : n=1; should be written as y==1?0:1;.

There is no error in program, but value of n is being 1, why;.

y == 1 ? n=0 : n=1; should be replaced by
n=(y==1)?0:1;
n=(y==1)?0:1;

What do you mean by ((y == 1) ? n) = 0 : n = 1;
