After calling Macro SET(val,bit) , the bit number 2 (i.e. third bit) will be set/hight and the value of val will be "0001 0101" that will be 0x15 in Hexadecimal.
C program to Check if nth Bit in a 32-bit Integer is set or not
WebpossibleSubsets(A, N): for i = 0 to 2^N: for j = 0 to N: if jth bit is set in i: print A[j] print ‘\n’ Implementation: void possibleSubsets(char A[], int N) { for(int i = 0;i < (1 << N); ++i) { for(int j = 0;j < N;++j) if(i & (1 << j)) cout << A[j] << ‘ ‘; cout << endl; } } WebShift num to right n-1 times. Take bitwise and with 1 and the result is our answer. Code #include #include using namespace std; int main () { int num, n; cout << "Enter number\n"; cin >> num; cout << "Enter bit number you wish to obtain\n"; cin >> n; cout << "Answer:" << (1 & (num >> (n - 1))); } Output: neil emmison twitter
Define Macros to SET and CLEAR bit of a PIN in C - Includehelp.com
WebThe idea is to use bitwise << and & operators. Using the expression 1 << (k - 1), we get a number with all bits 0, except the k'th bit. If we do bitwise AND of this expression with n, i.e., n & (1 << (k - 1)), any non-zero value indicates that its k'th bit is set. For example, consider n = 20 and k = 3. 00010100 & (n = 20) 00000100 (1 << (3-1)) WebJan 6, 2024 · Problem statement: Write a C program to check if nth bit is set or not in a 32 bit integer. Solution: Pre-requisite: input no (32 bit longer), nth bit Algorithm Right shift by n times to get the nth bit at LSB Do a bitwise and with 1 (only LSB is set of 1, other bits 0). IF result is 1, then nth bit is set Else Bit not set Example with explanation: WebJan 24, 2016 · C program set n th bit of a given number if it is unset otherwise unset if it is set. Example Input Input number: 22 Input nth bit to toggle: 1 Output After toggling nth bit: … it lives cast
