右运算 [yòu yùn suàn]
right operation
- 而使用插入迭代器赋值时，则会在容器中添加一个新元素，其值等于赋值运算的右操作数的值。
When we assign through an insert iterator, a new element equal to the right-hand value is added to the container. - 例如，假定一个5×5的卷积内核需要分别选取当前像素的左、右、上、下的各2个像素，以保证运算的正常进行。
That is, consider that a 5x5 convolution kernel needs 2 pixels to the left, top, bottom and right of the current pixel in order to perform properly. - 二元运算符+和-具有相同的优先级，它们的优先级比运算符*、/和%的优先级低，而运算*、/和%的优先级又比一元运算符+和-的优先级低。算术运算符采用从左到右的结合规则。
The binary + and - operators have the same precedence, which is lower than the precedence of *, / and %, which is in turn lower than unary + and -. Arithmetic operators associate left to right.
