WebNov 21, 2024 · The result is a bit-field if the left operand is a bit-field. For non-class types, the right operand is first implicitly converted to the cv-unqualified type of the left operand, and then its value is copied into the object identified by left operand. When the left operand has reference type, the assignment operator modifies the referred-to object. hershey figure skating club campWeb1 day ago · Usually what we want for the initial element is some identity element for the value type of the range with respect to the given binary operator.
