Left shift and right shift c++
NettetAn important thing to keep in mind is that shifting by 1 to the left is the same as multiplying by 2, while shifting to the right by 1 is the same as dividing by 2 then rounding down. C doesn't have a >>> operator, and shifting of negative numbers is undefined in C.

Nettet23. mar. 2024 · When the specified number of bits of the operand are shifted to the left then the same number of bits on the right are filled with 0s. The left-shift operator is represented by the (<< ) sign. If variable a = 1111100110001001 then a << 5 will be: A = 1111100110001001. a << 5 = 0011000100100000.
