shift-expression << additive-expression shift-expression >> additive-expression

The bitwise shift operators shift their first operand left (<<) or right (>>) by the number of positions the second operand specifies.

Example

In the following example, the right shift operator moves the data bits two positions to the right, thus changing the value of nNumA:

// Example of the bitwise right shift operator

int nNumA=8;   // beginning value is 8

nNumA >> 2;    // ending value is 2
