RE: How to write a C program to find the power of 2 in...
That's actually logical ANDingThe actual to determine whether a number is a power of 2 or not is --> bit wise AND the number under consideration with its previous number. if the result is zero then the number under consideration is power of 2Code: if (x & (x-1) == 0) number is a power of 2else number is NOT a power of two.
RE: How to write a C program to find the power of 2 in...
You are right. We should first check whether the given number is larger than 0. If it is larger than 0, we can use (x && (x-1) == 0) to determine whether x is power of 2 or not. If it is 0, then return 0. If x is smaller than 0, what should we do?
RE: How to write a C program to find the power of 2 in a normal way and in single step?
# include <stdio.h> # include <conio.h> void main() { int x; printf("Enter the value of x: "); scanf(" %d", &x); if((x & (x-1)) ==0) printf(" no. is power of 2"); else printf(" no. is not power of 2");
