Instructor: Professor Hong
## Review & Questions
## Quiz #1 * 20 minutes
## Bitwise Operators
## Bitwise Operators * <code>&</code> -- bitwise AND * <code>|</code> -- bitwise inclusive OR * <code>^</code> -- bitwise exclusive OR * <code><<</code> -- left shift * <code>>></code> -- right shift * <code>~</code> -- one's complement (unary)
## Bitwise Operators Example ``` #include <stdio.h> int main() { printf("5 & 4 = %d\n", 5 & 4); printf("5 | 4 = %d\n", 5 | 4); printf("5 ^ 4 = %d\n", 5 ^ 4); printf("5 << 2 = %d\n", 5 << 2); printf("12 >> 2 = %d\n", 12 >> 2); printf("~5 = %d\n", ~5); // Note 2's complement // 5 is 0000...0101 // Doing on's complement, we have // ~5 is 1111...1010 // which is MIN+sum(2^n) where n excludes n=0 and n=2 // Or simpler: -8 + 0 + 2 + 0 return 0; } ```
