Let me give you an example:For example, you can return a function in these situations:1, the number greater than 02, less than 0 of the number3, equal to 0 of the number (that is, 0)4, False (when failed)If you want to catch failure, you must use = = =because = = except will match the 4th case, will also match the 3rd case, because 0 is also false!
The three equals sign represents the same type of comparison object. A two

Too many programmers don't have much mind to focus on the programming fonts they face every day, and then the coding work takes a long time to stare at the screen and read some very complex text. A good font can greatly improve the pleasure of reading code and increase productivity.
This article describes 10 equal-width fonts for programming, which are free and work well.1. Source Code Pro

If you need to enter a large number of expressions such as "3+7+9" in an Excel worksheet and ask the cells to display their calculations, you'll have to type an equal sign "=" before each formula, which is a bit cumbersome. Here, the author tells you a method that allows you to omit the equal sign of the input process, the method is:
1. On the Tools menu, click Options, and the system pops up the Options d

A is said to being coprime to B if A, B share no common positive divisors except 1.Input for each test case, there was a line containing a positive integer N (1≤n≤1000000000). A line containing a single 0

In php, the average is equal to the full expression. in simple terms, it is a simple equivalent. In other words, it is very precise. next I will introduce it to you.

We generally compare whether two File objects are in the same File. Generally, java. io. File. equal () is used (). The equal () mentioned here does not compare whether the file content is the same, but whether the two file objects point to the same file.
The File equal () method actually calls compareTo () of the current File system FileSystem ().

To determine whether two objects are equal, you need to use equal to determine whether the addresses of these two objects are identical. In some cases, to determine whether two objects are equal,

x equals y.
greater than 0
x greater than y. or y is a null reference (Nothing in Visual Basic).

x equals y.
False
x does not equal Y.
Char a = null, or char a = ' ' is all wrong to define a null value. The following methods
In the previous blog, I shared with you how to calculate the circumference rate. Both the approximate value and the accurate value result are in the 3. 14 ...... but you can see the following picture to deduce the circumference rate.
It means to first draw an external square of the circle, and then convert the square into the n-Edge Shape of the circumference according to the figure, that is, the square is infinitely folded until it is equal to the c

If you want to use C ++ to generate a random number between 0--n-1, what would you do? You may say that it is very simple. See:
Srand (unsigned) Time (null ));Rand () % N;
Think about it, is the result random (of course, we do not consider the pseudo-randomness of the Rand () function )?
No, because the upper limit of rand () is rand_max. Generally, rand_max is not an integer multiple of n. If rand_max % = r, the probability of a value between 0 and R is larger, while the probability of a value
=: 1. Compare whether the operands at both ends of the operator are the same object. 2. The operands at both ends must be of the same type (between parent and child classes) before compilation. 3. Compare the address. If it is a comparison of specific Arabic numbers, the value is true if it is equal, for example: int A = 10 and long B = 10l and double C = 10.0 are both the same (true), because they all point to the heap equals with the address 10: 1.
