C – Shift Operators

Shift Operators:

• These operators are used to shift binary bits either to Left or Right
• The operators are,
  • Left Shift (<<)
  • Right Shift(>>)

Theoretical formulas:

• For Right Shift:  n/2^s
• For Left Shift:  n*2^s
  • Where ‘n’ is the data and ‘s’ is the number of bits to shift

Right Shift operator(>>):

int main() {             int x=32;             int y=x>>2;             printf(“y val : %d\n”, y);             return 0; }

32/22 32/4 8

Left Shift operator(<<):

int main() {             int x=2;             int y=x<<3;             printf(“y val : %d\n”, y);             return 0; }

2*23 2*8 16
