This article is about how to use vbscript to calculate the sum of 1 to 100. The editor thinks it is very practical, so share it with you as a reference and follow the editor to have a look.

We seldom use new Array to define arrays. Unexpectedly, new Array has such a wonderful use. Through new Array (n), we can create n empty elements, and at the same time, there is a blank space among n elements. Through join, we can put something in the middle of these blanks to form a special string we need, which inspired me. This feature makes it easy for me to achieve a "continuous operation of regular elements" without a loop. For example, to calculate the sum of values from 1 to 100. In the past, we needed to loop from 1 to 100 and then sum, but with this feature of the array, we can do it with a simple line of code, as follows:

The copy code is as follows:

Var iMagne summation eval ('0'+new Array (101) .join (' + (+ I)'))

In addition, you can do many similar mathematical operations, such as the following

The copy code is as follows:

Eval ('0'+new Array (11). Join (' + Math.pow (+ + iMagne2)') / / calculate the sum of squares from 1 to 10

Eval ('0'+new Array (100 impulse 2). Join (' + (iTunes 2)') / / calculates the sum of 2'4'6'.. 100

These calculations, which we used to do through loops, can now be cleverly done with one line of code, and we have to marvel at the hidden dexterity of the programming language. there are always too many things waiting for us to discover in the programming world.

Change the above JavaScript code to VBS, which is the so-called ashes solution of the VBS exercise:

The copy code is as follows:

Dim a (101)

Execute (Join (a, "s=s+i:i=i+1:"))

MsgBox s
