Question: Design an algorithm with a WHILE-loop for finding the mean of the elements in an array of the numeric type.

ANS:




Shouldnt there be a step 'Input item*' before 'sum = sum + item*' ?

*There should be a 'i' here. There is error it cant show.

Please post here if you know. Thank you!!!!!!

吾係好明你問咩,,不過都試下解一解,
我估你係問緊點解"i = i +1;" 吾可以響" sum = sum + i;" 前面,
其實好簡單,
如果你行左i果句先, 咁個sum就會係sum=sum+"2",
因為你個i 加左1;

其實你係問個array定係問緊個loop嫁!?

你可以當佢叫你寫一個procedure(唔係成個program), aim to find the mean of one element. 至於 item 既array 係咩呢,,就可以唔洗理喇. 所以答案冇錯. (如果你話要加 readln(item) 既,,咁 how about n? ,,所以唔洗加 Input item* ).
