Correct use of the two assignment statements is very important for the design and simulation

4.1.4 Relational operatorsIn C + +, in addition to arithmetic operations that require arithmetic operators to subtraction the data, we sometimes need to manipulate the relationship between the data, that is, to compare the size of the two data to derive the size relationship between them. In the real world, comparisons of this size relationship are very common. For example, the tomato at this booth 5 yuan a catty, while the other one of the same tomato only sold 3 yuan a catty, 5 and 31 compared

Value Assignment: The value of the argument is assigned to the row parameter, and the modification of the row parameter does not affect the value of the argument.For example: root copy is the same. For example, I have one? H House, I give you building materials, you built a house that is identical to my house, what you do in your house will not affect me, what I do in my house will not affect you, independent of each other. The code is as

-called default assignment operation refers to all the fields in the stack that are in the object and replicate accordingly. However, if the object has a field on the heap, it does not allocate space on the heap for the copied object, but only points to the same address on the same heap.After performing the default assignment operation such as B=a, its memory allocation is as follows:Therefore, for the defa

Assignment related operations in Ruby programming and ruby programming assignment In earlier versions of Ruby, the return value of the value assignment statement is the return value of the method that sets this attribute. In Ruby1.8, the value of the value assignment statement is always the value of the parameter, and
