Algorithm
-
Input:
- Accept the base (the number to be raised) and the exponent (the power to which the base is raised) as input.
-
Initialize result:
- Set a variable
result
to 1. This will be used to accumulate the result.
- Set a variable
-
Loop for exponent times:
- Use a loop to iterate from 1 to the exponent.
- In each iteration, multiply the
result
by the base.
-
Output:
- After the loop, the
result
contains the power of the number. - Print or return the result as the output.
- After the loop, the
