C Programming - Control Instructions - Discussion

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

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

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

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

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

So it will print 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.

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

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.

#include<stdio.h>
int main()
{
int k, num = 30;
k = (num < 10) ? 100 : 200;
printf("%d\n", num);
return 0;
}

Here in this program,

k = (num <10)?100:200;

The condition is false so the result is 200 but thus in the next statement printf("%d\n", num); we print the value of num so the result is 30. what is assigned it previously?
