What is the meaning of compound operator '*=' in C? What function does it performs.

Question

Ex. int i=2, a;
a *= i;
printf("%d", a) ;

Answer 1

Since, the value of a is not assigned depending upon the compiler its value can be set to either 0 or some garbage value. So the new value of a is value of ("a" assigned) *(i)

Answer 2

With C you will get 16.
In Java it will be an error because 'a' don't have value.

Answer 3

most likely multiply

Answer 4

i *= 2;
is equal to
i = i * 2;

Answer 5

Ya. But what would be the output of my example code?

Answer 6

This means that a has been assigned the value 8?
