How to set nth bit in c
WebSetting nth bit of a given number using bitwise operator. Logic to set nth bit of a number We use bitwise OR operator to set any bit of a number. Bitwise OR operator evaluate each bit … WebSetting a bit. Use the bitwise OR operator ( ) to set a bit.number = 1UL << n; That will set the nth bit of number.n should be zero, if you want to set the 1st bit and so on upto n-1, if you want to set the nth bit.. Use 1ULL if number is wider than unsigned long; promotion of 1UL << n doesn't happen until after evaluating 1UL << n where it's undefined behaviour to shift …

WebNov 8, 2024 · Any bit Set bit = Toggle which means, 0 ^ 1 = 1 1 ^ 1 = 0 So in order to toggle a bit, performing a bitwise XOR of the number with a reset bit is the best idea. n = n ^ 1 << k OR n ^= 1 << k where k is the bit that is to be cleared Below is the implementation of the above approach: C++ C Java Python3 C# Javascript WebThe nth bit of the number is zero. This approach is also called as bit masking. This is all about the C++ program to find the nth bit of number. You can implement the same logic in any other programming language like C, Python.

In this example, we are toggling bit number 2 (i.e. third bit of the val), initially bit 2 is 0, after calling TOGGLE (val, bit) first time, the bit 2 will be 1. Hence, the value of val will be "0001 0100" – thus, the output will be 0x15 in Hexadecimal. Now, the bit 2 is 1, after calling ...
