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. 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 ... WebJan 19, 2024 · byte datatype has a range from -128 to 127 and it requires very little memory (only 1 byte). It can be used in place of int where we are sure that the range will be very small. The compiler automatically promotes the byte variables to type int, if they are used in an expression and the value exceeds their range.
