Answer 1

It is changing each time because the value of 'a' is not defined : you didn't initialize the variable 'a'.

Answer 2

Because the C (and C++) language is not safe. It lets you declare variables without initialisation.

Here, 'a' contains some random values from the stack.

Answer 3

I was checking if the output will come or not?

But why the output is coming if i have not initialised the value of a?

Answer 4

Thanks Both of You👍
