我把你的發佈代碼儘可能地清理乾淨 - 這真是一團糟 - 如果你想讓人們花時間閱讀你的代碼並幫助你，請在代碼格式化方面加倍努力。 – 2010-12-09 11:26:16

arr1=(int*)memory_Malloc(di*sizeof(int)); 
    for (i=0;i<zj;i++){ 
     arr1[i]=0; 
    }

什麼是memory_Malloc？

如果zj比di時，你將在arr1

fgets(y,100,fp1); 
count=0; 
while (!feof(fp1)){ 
    fgets(y, 100, fp1);

外面寫拿到1 y從fp1，然後開始循環，然後得到另一y從fp1：你剛剛「丟失「第一個y
```
if(count>=zj) 
```
S這不是count>=n？數組arr有空間用於n元素。
```
memory_Free(arr,n*sizeof(int)); 
```
什麼是memory_Free()？
你爲什麼要傳遞2個參數？
arr大小不是n*sizeof(int)：如您在memory_Malloc寫道，這是n*sizeof(int*)

我想我已經得到了它。

arr大小不是n*sizeof(int) =他們是指針，所以應該是n*sizeof(int*)而不是。
