WebFeb 7, 2024 · The & operator computes the bitwise logical AND of its integral operands: C# uint a = 0b_1111_1000; uint b = 0b_1001_1101; uint c = a & b; Console.WriteLine (Convert.ToString (c, toBase: 2)); // Output: // 10011000 For bool operands, the & operator computes the logical AND of its operands. The unary & operator is the address-of operator. WebBit Fields in C In C language, we have union and struct data types where we can declare user-defined data types. The size of the struct depends on data members. But sometimes, we do not need such a huge size of the data type, because it occupies memory, and it creates a waste of memory. Example 1: #include struct dob { int date;
