Answer:
p(x,n)
1. if(n==0) [if power is 0]
2. then result =1.
3.else
4. { result=1.
5. for i=1 to n.
6. { result = result * x. } [each time we multiply x once]
7. return result.
8. }
Let's count p(3,3)
30, so come to else part.
i=1: result = result *3 = 3
i=2: result = result *3 = 9
i=2: result = result *3 = 27
Explanation:
here the for loop at step 4 takes O(n) time and other steps take constant time. So overall time complexity = O(n)
Answer:
In a function prototype the heading is followed by a semicolon, whereas in a function definition the heading is followed by a function block.
Explanation:
As the function prototype only declares the function and the function definition defines the operations in the function.
e.g:
add(int x, int y); is the prototype
add(int x, int y)
{
int sum;
sum x
y;
} is the function definition.
