Question

Write a c program to find the power of a number without using * opeartor.

Answer 1

We can calculate power by using repeated addition.

For example to calculate 5^6.

1) First 5 times add 5, we get 25. (5^2)

2) Then 5 times add 25, we get 125. (5^3)

3) Then 5 time add 125, we get 625 (5^4)

4) Then 5 times add 625, we get 3125 (5^5)

5) Then 5 times add 3125, we get 15625 (5^6)
