SpletIn the C programming language, operations can be performed on a bit level using bitwise operators.. Bitwise operations are contrasted by byte-level operations which characterize the bitwise operators' logical counterparts, the AND, OR, NOT operators. Instead of performing on individual bits, byte-level operators perform on strings of eight bits (known …

Splet19. jul. 2005 · Need to swap the bits as: 40 in Hex => 64 in Dec => 0100.0000 in Binary What is the easiet way? Assuming that you want to use 8 bits of whatever bytes you have, you could use char swapbyte(unsigned char c) { unsigned char result=0; for(int i=0;i<8;++i) { result=result<<1; result =(c&1); c=c>>1; return result; Or, another possibility Splet27. jun. 2024 · Just use the appropriate masks (0x000F and 0xF000) and shifts (12) to swap the highest and lowest nibble of a 16 bit value. But don't forget to let the middle bits untouched (return them too): C++ #define swap (v) ( ( ( (v) & 0x000F) << 12) ( ( (v) & 0xF000) >> 12) ( (v) & 0x0FF0)) gentex dudley massachusetts
Swap bits in a given number - GeeksforGeeks
SpletTo perform bit-level operations in C programming, bitwise operators are used. Bitwise AND Operator & The output of bitwise AND is 1 if the corresponding bits of two operands is 1. If either bit of an operand is 0, the result of corresponding bit is evaluated to 0. In C Programming, the bitwise AND operator is denoted by &. SpletFirst shift the bit in given position to right-end. This can be achieved by the code below. for p’th bit – n & (1 << p)) >> p) for q’th bit – (n & (1 << q)) >> q) 3. Next step is to perform XOR operation. If the bits are the same, no need to swap. 4. If the bits are not the same, just toggle the bits. This can be achieved by the code below. Splet11. feb. 2024 · To set a bit, we'll need to use the bitwise OR operator − Example #include using namespace std; int main() { int i = 0, n; // Enter bit to be set: cin >> n; i = (1 << n); // Take OR of i and 1 shifted n positions cout << i; return 0; } Output If you enter 4, This will give the output − 16 because 16 is equivalent to 10000 in binary. gentex corporation - zeeland mi
