Step by Step solution about How to resolve the algorithm Exponentiation operator step by step in the Julia programming language

The provided Julia code defines a function named pow that calculates the exponentiation of a given base raised to a given exponent. Here's a detailed explanation of the code:

1. function pow(base::Number, exp::Integer): This line defines a function named pow that takes two arguments: base and exp. The base argument is type-annotated as a Number, indicating that it must be a numeric value, while the exp argument is type-annotated as an Integer, indicating that it must be an integer (whole number).

2. r = one(base): This line initializes a variable r with the value of one for the given base. The one() function returns the multiplicative identity for a given type, which is 1 for numeric types. In this case, r is initialized to 1, regardless of the type of base.

3. for i = 1:exp: This line initiates a for-loop that iterates from 1 to exp. This loop repeats exp times.

4. r *= base: Inside the loop, r is multiplied by base. This action raises base to the power of i for each iteration.

5. return r: After the loop completes, the function returns the value of r, which represents base raised to the power of exp.

In summary, this code defines a function that calculates the exponentiation of a given base raised to a given integer exponent by iteratively multiplying the base by itself for the number of times specified by the exponent.

function pow(base::Number, exp::Integer)
  r = one(base)
  for i = 1:exp
    r *= base
  end
  return r
end
