please answer fast

Answer 1

Answer:

When multiplying two integer values, the compiler will never by itself convert the result to a floating point type. That is, if you multiply two int values, the result too will be an int value.

So, what you're code is effectively doing is:

int a = 10;

int b = 20;

int tmp = a * b; // Result is actually an int

double c = (double)tmp; // Convert to a double.

Thus, the result would only overflow if it cannot be stored within an int. The conversion and assignment to a double is done only after the result is calculated.

hope it helps you!
