bool isPowerOfTwo(int n) { if (n == 0) return false;

return (ceil(log2(n)) == floor(log2(n))); }

void printHello(int n3) { for (int i = 0; i <= n3; i++) { if (isPowerOfTwo(i)) printf("HELLO"); else printf("%d", i); } printf(" "); } int main() // Testing the code {

printHello(3); printHello(7); printHello(10); printHello(1); }

Can someone explain each line of the C code?
