WebFeb 6, 2024 · The signed shift n>>31 converts every negative number into -1 and every other into 0. When we do a -n>>31, if it is a positive number then it will return -1 as we are doing -n>>31 and the vice versa when we do for a negative number. But when we do for 0 then n>>31 and -n>>31 both returns 0, so we get a formula: 1 + (n>>31) – (-n>>31) WebNov 12, 2010 · 26 Using only bitwise operators ( , &, ~, ^, >>, <<) and other basic operators like +, -, and !, is it possible to replace the "==" below? int equal (int x, int y) { return x == y; } c binary bit-manipulation Share Improve this question Follow edited Nov 12, 2010 at 14:07 Roger Pate asked Nov 12, 2010 at 4:38 not_l33t 1,285 4 15 17 1

WebMar 8, 2024 · Bitwise and shift operators that perform bitwise or shift operations with operands of the integral types Equality operators that check if their operands are equal or not Typically, you can overload those operators, that is, specify the operator behavior for the operands of a user-defined type. WebUse the bitwise OR operator ( ) to set a bit. number = 1UL << n; That will set the n th bit of number. n should be zero, if you want to set the 1 st bit and so on upto n-1, if you want to set the n th bit.
