if x=X here then
output:

1201

because printing is done from right to left in printf and here,
x<30 means true and in c it is 1 , so output is 1

x=20 means x is assigned to 20 now and then itz value is printed and


x!=15 will give true becuz now the value is 20 and in c true means 1

Through Visual studio
int x=15;

printf("%d %d %d",x!=15,x=20,x<30);

gives : 1 20 1

Ans : 1 20 1
Reason : in printf() calculation is done from right to left so
step 1- x<30 is evaluated n its results will be 1(true) then
step 2- x=20 is is evaluated n its results will be 20 (as 20 is assign into x ) then
atep 3- x!=15 is evaluated n its results will be 1(true) since last values of x is 20 not 15
finally results of all steps are printed from left to right.

Note: printf works from right to left (r to L)

in first x<30 a test condition is there so output of dat test is true which means 1 in c so print 1

in second assingment is happing so it assing value n den print value of x which is equal to 20 now

in 3 condition is trueso it will print 1

o/p=1201

The behavior is undefined; the arguments to printf aren't guaranteed to be evaluated in any particular order. The *result* of each expression is guaranteed to be passed in the order specified, but that's not the same thing. Its not guaranteed that x!=15 will be evaluated before x=20, and its not guaranteed that x will be evaluated after x=20. The result could be "1 20 20" or "1 20 15" or "0 20 20" or something completely different.

It will give error!! X : undeclared identifier.
if both are small x then it give 1 20 1 as result
