各位前輩,我要如何才能使這個while一直讀,每次32個字,然後把全部的值寫回去.

我並沒有認真去看你的程式在做啥(看起來好像是從檔案讀取資料然後處裡,而每筆資料的長度32Byte)?而且這個題目看起來像作業
不過我還是提供一些方向給你,
假設你每筆資料長度一樣時,對於此資料可利用struct來定義各欄位
而各欄位用陣列定義其大小,不用每個元素都單獨定義
讀檔時就一次讀一筆資料(struct),一直到file eof為止
還有許多許多的讀檔處理方式,端看你如何運用而已

引言:
我要如何才能使這個while一直讀,每次32個字,然後把全部的值寫回去.
FILE *charFile,*newCharFile;
char in[100];
char input[100]; charFile = fopen("TEST.c", "rb");
if (charFile == NULL) return; //開啟檔案失敗時離開 newCharFile = fopen("REPORT.c", "wb");
if (charFile == NULL)
{
fclose(charFile);
return;
} while(fread(input, 32,1,charFile)==1) //每次讀32bytes,不足32bytes離開
{ // 在這裡放你資料轉換的程式 fwrite(in, 32, 1,newCharFile); //寫32bytes到新檔
} fclose(charFile);
fclose(newCharFile);
