C conditional operator with assignments – behavior and output: Is there any error in this program, and what will it print? #include <stdio.h> int main() { int n = 0, y = 1; y == 1 ? n = 0 : n = 1; if (n) printf("Yes "); else printf("No "); return 0; }

Introduction / Context:
This question tests whether writing assignments inside the conditional operator is valid C and whether such code compiles without error. It also asks you to infer the resulting output of the program flow.

Given Data / Assumptions:

• y is 1; thus y == 1 is true.
• The conditional operator assigns to n either 0 or 1.
• An if prints “Yes” when n is nonzero, else prints “No”.

Concept / Approach:
The conditional operator ?: chooses one of two expressions. Using assignments as operands is legal. When the condition is true, the left operand executes; otherwise, the right operand executes. Since y == 1 is true, n is set to 0, and the subsequent if (n) evaluates as false, so “No” is printed. There is no declaration or syntax error here; the code is valid and well-formed.

Step-by-Step Solution:
Evaluate condition: y == 1 → true.Execute true branch: n = 0;Test if (n) → false → go to else.Print No.

Verification / Alternative check:
Parenthesizing for readability, y == 1 ? (n = 0) : (n = 1);, produces identical behavior.

Why Other Options Are Wrong:
None of the listed errors apply: the declaration is correct, syntax is valid, and assignments target a proper lvalue (n).

Common Pitfalls:
Assuming the conditional operator requires pure values; it can contain side effects like assignments. Another pitfall is expecting “Yes” because of the true condition, forgetting that the true branch explicitly forces n to 0.

Final Answer:
None of above
