For example: const PI=3. 1415926 AP
The brand "NAME= const memory”

the data type conversion:
AP 1)

AP 2)
The brand
Dim a, B, C
The brand
a=inputbox ("A:”,
z，input radius")
The brand
b=Inputbox ("B:”,
z，input radius")
Which was c=
(a+b) *2
Which was Msgbox (c)
Which was 1 and 2 when this input is 24
为什么会不一样呢？在数学上c=(a+b)*2和c=a*2+b*2是等 价的，〃+〃上，在VBS中，+不仅仅是加 号的意思还表示把两个字符串连接起来，例如 "Hello"+"World"="HelloWorld" have you understood?你还记得 InoutBox函数的返回值吗？是字符串！这就看出问题了吧，在编程 中〃 1〃不等于(0)1, 〃1〃是一个字符，而1是一个数，所以a, b都是 字符串变量，〃1〃+〃2〃二〃12〃，这就好像我们小时跟伙伴开玩笑问他 们1+1二?一样，我们总是笑着说〃错啦，应该是11〃.但为什么，a可以 *2却不发生错误呢？这时VBS比较智能的一个表现，如果这个字符 串的内容是一个数且对他进行数学运算，则把字符串强制转换A number of participating in operation, if the string representation of a number, but not in math, but in string operations (merger) as string processing, so you see the a+b=12, then the results of
