// Question 3. What will be displayed on the screen package main import "fmt" import "math" func main() { i := int32(math.Pow(2, 64)) fmt.Println(i) }

In this code, there is an attempt to calculate 2 to the power of 64 using math.Pow, which returns a float64, and then the result is cast to int32.

However, 2^64 = 18446744073709551616 — a number that does not fit into an int32 (maximum int32 is 2147483647). When casting a large number to int32, overflow occurs, and the result will be 0, because 2^64 is exactly 1 << 64, and int32 only stores 32 bits.

Thus, the program will output:

0

If you use int64, there would also be overflow, since 2^64 does not fit into int64 (maximum 2^63-1). math.Pow returns a float64, and casting to an integer type truncates and overflows.
