Assignment operatorsare used to assign the value/result of the expression to a variable (constant – in case ofconstant declaration). While executing an assignment operator based statement, it assigns the value (or the result of the expression) which is written at the right side to the variable...
PORTC = 01001111// Now 5th bit is cleared It may seem unnecessary to use the NOT operator. We can as well write PORTC = PORTC & DF or even PORTC = 11011111. But it is easier to identify the bit in question in 00100000, rather than 11011111. Hence programmers generally prefer to ...
In C programming, assignment operators are used to assign values to variables. The simple assignment operator is =. C also supports shorthand assignment operators that combine an operation with assignment, making the code more concise. Key Topics: Simple Assignment Operator Shorthand Addition Assignment...

OperatorEquivalent &= and_eq |= or_eq ^= xor_eqC++ specifies these operator keywords as alternative spellings for the compound assignment operators. In C, the alternative spellings are provided as macros in the <iso646.h> header. In C++, the alternative spellings are keywords; use of <is...
You could delete the default copy constructor or default copy assignment operator for each base class, but that would be onerous and result in lots of duplicated code. Also, the deletion would get hidden among the base class methods.
