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...
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...

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.
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...

The = (equal to) symbol is defined as assignment operator in Python. The value of Python expression on its right is assigned to a single variable on its left. The = symbol as in programming in general (and Python in particular) should not be confused with its usage in Mathematics, where...
