Splet03. nov. 2024 · Consider the code below which swaps nibbles in a byte: #include unsigned char swapNibbles(unsigned char x) { return ( (x & 0x0F)<<4 (x & 0xF0)>>4 ); } int main() { unsigned char x = 100; printf("%u", swapNibbles(x)); return 0; } Why is anding with 0x0F and 0xF0 necessary? Instead I can just write SpletGiven a number N, swap the two nibbles in it and find the resulting number. Input: N = 129 Output: 24 Explanation: 129 in binary is 10000001, two nibbles are (1000) and (0001) If we swap the two nibbles, we get 00011000 which is 24 in decimal. You don't need to read input or print anything.
A Program to Convert Two Nibble into A Byte - YouTube
SpletFor example 100 is to be represented as 01100100 in a byte (or 8 bits). The two nibbles are (0110) and (0100). If we swap the two nibbles, we get 01000110 which is 70 in decimal. But, for smaller numbers that are less than 8 bits, need to be added extra zeros in the front. I am strucked with how to push extra zeros after splitting the obtained ... Splet10. mar. 2008 · you could shift the top nibble 4 bits right and the lower nibble 4 bits left then OR them together, e.g. Expand Select Wrap Line Numbers y = ((x >> 4) & 0x0f) ((x << 4) & 0xf0); thats really an expert answer!! sum wave
Interchange 2 nibbles of byte - C / C++
SpletC program to swap two words/bytes. This program will swap two bytes/words of an integer number, here this operation is implemented using bitwise shifting and bit masking. Swapping two Bytes/Words using C program SpletI have to Write a C program that will swap any two nibbles of a long int x (64-bit integer).A nibble is a four-bit aggregation. There are two nibbles in a byte. For this problemthe index of the least significant nibble is 0, and the index of the most significantnibble is 15 (so 0 <= m, n <= 15). So, if x = 0x0123456789ABCDEF (a 64-bitinteger ... SpletLet’s see how we can swap the two nibbles of a byte: Perform bitwise AND operation with hexadecimal 0F to separate the lower nibble from the byte Perform bitwise AND operation with hexadecimal F0 to separate the upper nibble from the byte Take the right nibble and left shift << by 4 positions Take ... palliative care north east
