What is the difference between "+" and "&" operator when joining
strings?
加入两个真正的字符串时差别不大。
" aaa" +bbb会得到与aaa相同的结果。 &安培; " BBB"即aaabbb
但是，如果一个表达式是一个数字而一个是一个字符串，那么事情就不那么清楚了......
" 5" + 10将给出数字15.5。转换为
fly上的数字。
而5 &安培; 10将给出字符串510。 10在运行中转换为
字符串。
+应该只用于添加数字，&应该用来
连接字符串。
Not much difference when joining two real strings.
"aaa" + "bbb" would give the same result as "aaa" & "bbb" i.e. "aaabbb"
However, if one expression is a number and one a string then things are
less clear...
"5" + 10 will give the number 15. The "5" is converted to a number "on the
fly".
Whereas "5" & 10 will give the string "510". The 10 is converted to a
string "on the fly".
+ should really only be used to add numbers, and & should be used to
concatenate strings.
非常感谢！
