Set bit using macro
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 ...

WebThe trick is to create an 8–bit (1 byte) version of the table, then iterate over each byte in the integer to be checked and summing the table lookup results. 1 byte with all its bits set is 255 in decimal ( 11111111 in binary), and all bits unset is 0 in decimal ( 00000000 in binary). So, the lookup table should be of size 256 (0-255).
