Note: There is no block-level scope in ecmascript, so variables defined inside the loop can also be accessed externally.eg1 var count=10; 2 for (var i=0;i) {3
. Generator:Only the corresponding data is generated during the call, and there is only one _ next _ () method.
If the list elements can be calculated by some algorithm, can we continue to calculate the subsequent elements in the loop process? In this way, you do not need to create a complete list to save a lot of space. In Python, this type of computing mechanism is called a Generator ).
Creation method:1) The simplest is to change [] of a list generation type to (), and a generator is created.

To get this topic, we will first think of using loops to complete.But not every operator is a "+" sign.Therefore, we are here to use (-1) of the I-side to do "+" "-" number control.The loop variable i is then treated as the denominator.Here we have the idea of the loop body is basically OK.It is important to note that the calculation results here are expressed in decimals, so it is not possible to define variables with int integers.The code is as follows:#include #includeintMain () {inti; floats

ENVI 5 of Service Pack 3 has the following features:1. sensor, data format, metadata
· ENVI reads and displays images from the following sensors:
· LANDSAT-8
· EO-1 Ali and Hyperion
· NPP viirs
· Dubaisat
Pleiades Level-1B
· RapidEye Level-1B geotiff file metadata; ENVI previously only supports nitf l1b data format.
· Radiation Correction tools for LANDSAT-8 and EO-1 data.
· When you open the NPP viirs file
1. In JavaScript, the arguments object is a more specific object, which is actually a built-in property of the current function. Arguments is very similar to an array, but is not actually an array instance. Can be confirmed by the following code (of course, in the function Funcarg, the call arguments is not necessarily written funcarg.arguments, write arguments directly).1 ARRAY.PROTOTYPE.TESTARG = "Test"; 2 function Funcarg () {3 alert (FUNCARG.A

Auto enables the compiler to automatically parse the type that an expression belongs to
Auto generally ignores the top-level const, preserves the underlying const, and if you want the inferred auto type to be a top-level const, you need to explicitly specify the const auto
