WebNov 27, 2024 · In C++, there are a total of six bitwise operators. The six bitwise operators are bitwise AND (&), bitwise OR ( ), bitwise XOR (^), left shift (<<), right shift (>>), and bitwise NOT (~). The & (bitwise AND) in C++ takes two numbers as operands and does AND on every bit of two numbers. The result of AND is 1 only if both bits are 1.

Say you want to hold the number 1.23 (and bit-shift it later). You would store 123 in an int, and every time you accessed the variable you would divide the value by 100: Code: ? 1 2 3 int i = 123; i = i << 3; printf("%f", i/100.0); I hope this helps. 05-24-2005 #3
