What value will the variable 'y' hold after executing cube(10) in the cube function provided?

The function 'cube' is likely designed to calculate the cube of a number, which is the result of raising that number to the power of three. In this case, when you call cube(10), you are asking the function to compute (10^3).

The calculation goes as follows:

[ 10 \times 10 \times 10 = 1000 ]

Thus, after executing cube(10), the variable 'y' will hold the value of 1000, which represents the cube of 10. This understanding is fundamental when working with functions that perform arithmetic operations, particularly exponentiation in this case. It illustrates how to apply the concept of powers in a practical programming scenario.
