An Introduction To Programming Through C++ || NPTEL Week-5 Programming Assignment 5.

 Write a function that takes a number b, and a number N, and returns true/false indicating whether N is a power of b, ie bk=N for some non negative integer k. The function returns true if N can be expressed as a power of b, and false otherwise.

Use the following function signature :

bool isPower(int b,int N).

The following code will be there, but won’t appear in your editor :

main_program{

int b,N;

cin>>b>>N;

if(isPower(b,N))

cout<<"Yes"<<endl;

else

cout<<"No"<<endl;

}

This invisible code will test your function. This code will read the values b and N from the test case and print out “Yes” if your function returns true and “No” otherwise.

You don’t need to write/copy the main program. You just need to write the isPower function, without the main_program or any of the header files.

Note : Ensure that the name of the function is isPower and it takes the two parameters and returns true or false without printing anything.

Explanation of Sample Testcase 1

Input : b=2, N=1024

Output : 1024 can be expressed as 210. So the function returns true and Yes gets printed out by

the invisible code.
