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
解析 = 在C语言中,赋值运算符用于将右操作数的值赋予左操作数,语法形式为`=`。例如`int a = 10;`中`=`表示将`10`赋给变量`a`。混淆点可能包括比较运算符`==`(判断相等),但题目明确询问的是赋值运算符,因此正确答案是`=`。题目结构完整且无歧义,直接对应知识点即可确定答案。
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, the Bitwise OR Assignment |= operator is a compound assignment operator that performs a bitwise OR operation between two operands and assigns the result

In the example below, we use the assignment operator (=) to assign the value 10 to a variable called x:Example int x = 10; Try it Yourself » The addition assignment operator (+=) adds a value to a variable:Example int x = 10;x += 5; Try it Yourself » A list of all...
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...
而assignment operator呢? Foo foo1; Foo foo2; foo2 = foo1; 以上會執行foo2的assignment operator。 所以簡單的說,copy constructor和assignment operator都在做『copy』的動作,當資料是pointer,也就是動態資料時,就必須重新改寫,否則只會copy pointer,而不是copy data。
