C programming

Question

#include<stdio.h>

int main()

{ int a=10,b=20,c=30;

c==a==b;

Printf("%d%d%d",a,b,c);

return0;}

Answer 1

Output: 102030

Explanation: Since "==" is a relational operator and not an assignment operator, value of none is changed.

                     It's just evaluating whether they are equal or not without performing any assignment.

NOTE: This code isnt properly formatted so might not produce output.

what is the associativity of equality operator??

---

@ Shubhanshu  Both == and != have the same precedence with associativity left to right.

Answer 2

a == b is checked if they are equal .... they are not equal

 therefore returns 0 which is assigned to c

therefore a=10 b =20 c =0

ANS - 10 20 0

Comments

But the output is 102030 please explain

---

Although comparison of A and B returns 0 but that in fact is not assigned to C. So C remains unchanged.

got it :)

if it was c = a == b then my logic was correct

Answer 3

10 20 30
== is relational operator not the assignment operator. So value of a.b.c has not changed
