> operator (c reference).

The Shift Right operator (> moves the first operand to the right by the number of bits specified by the second operand.

Remark. If the first operand is int or uint (32 digits), the shift number is given by the lower five bits of the second operand (second operand & 0x1f).

If the first operand is long or ulong (64 digits), the shift is given by the lower six bits of the second operand (second operand & 0x3f).

If the first operand is int or long, the right shift is an arithmetic shift (the high-order vacancy is set to the sign bit). If the first operand is of type uint or ulong, then the right shift is a logical shift (the high bit is padded with 0).

User-defined types can override >> operators; The first operand must be of type user-defined, and the second operand must be of type int. For more information, see Operator. When you overload a binary operator, the corresponding assignment operator, if any, is also implicitly overloaded.

Example. / cs_operator_right_

using system;

class mainclass

static void main()

int i = -1000;

Output: -125

You can't overload the AND >> operators in C.

There is no <<> such a symbol in C, you are an illegal operator. c doesn't seem to have such a thing as an overloaded operator.

That's how I fell in love with you.

Operator "also needs to be changed. Because you declare with & in class, and you don't have it in the implementation, this makes the compiler embarrassed.

c There are three forms of readout.

Most of the means of implementing input are with readline() example int i;

string s=;

i = ;or i = ; Obtain the required data by string conversion.

OOP is a way of thinking, regardless of the language.

It's just that different languages have different levels of support.

You seem to know the OOP perfectly.

You can refer to the blog in my space, there is an example of a fractional class under the C++ classification, I hope it can help.

Overloading is the arithmetic function of the actual operator, for example, class a and class b, class a has the variable aa, class b has the variable bb, the usual way is + = xx, after overloading it is a + b = xx,

Let's review it more, it's not difficult, the knowledge you learn is your own, and no one can take it away.

Study hard and stop fooling the teacher.
