C Programming - Control Instructions - Discussion

Actually we don't have any use of K there, because it is asking for num value in print out statement.

Its a type of question to know the concentration of a user.

step 1: num = 30
step 2: k = 200
step 3: print the value of num i.e 30;

In the program we are printing the value of num. We are not printing the value of k. So the output is 30.

Step 1: int k, num=30; here variable num is initialized to'30',
variable k is declared, but not initialized.
Step 2: k = (num < 10) ? 100 : 200; is nothing but
if(30 < 10)
k=100 ;
else
k=200 ;
Hence this condition will be failed. And k value
becomes 200(k=200)
Step 3: printf("%d\n", num); here it is printing num value but
not asked about to print k value.
So finally will get output 30.

It have the value of num not of k % its 30.

So it will print 30.

I don't understand the k=(num< 100) 100:200

Here if condition is not satisfied so it assumes the garbage value.

Does not use ternary operator. Because simply say that declare vale 30. Just print out the declare value.

Thanx Meenu, I was not knowing the meaning of this statement. It really helped me.

Here num=30 is assigned the value when you compare proparly 30<10 it false No than he willbe stop and they cannot exicuted the next statment and than 30 will be print.
