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...

In C language lvalue appears mainly at four cases as mentioned below: 在C语言中,左值主要出现在以下四种情况下: Left of assignment operator. 赋值运算符的左侧。 Left of member access (dot) operator (for structure and unions). 成员访问(点)运算符的左侧(用于结构和联合)。 Right of address-of...
MyClass& MyClass::operator=( const MyClass& other ) { x = other.x; c = other.c; s = other.s; return *this; } In general, any time you need to write your own custom copy constructor, you also need to write a custom assignment operator. What is meant by Exception Safe code?
OperatorEquivalent &=and_eq |=or_eq ^=xor_eq C++ 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 <iso64...

The simple assignment operator (=) causes the value of the second operand to be stored in the object specified by the first operand. If both objects are of arithmetic types, the right operand is converted to the type of the left, prior to storing the value. ...
