這樣做有利於對一個朋友，一個基本的程序，它從一個文本文件中讀取行，並將其轉換成存儲在malloc的整數給我一個運行時堆棧溢出分配的數組（文本中也給出了大小）。問題在於，很長一段時間沒有C.調試這個美麗，它給了我一個堆棧溢出的錯誤信息，在我評論你的現場。嘗試了函數參數的不同變體：int * A []，int * A [N] ..仍然讓我在運行時跳起來。

Answer 1

你在read_file_successful()分配N * LINE_LENGTH堆棧空間。算一算。那是10 * 65537 * 6或3932220字節。從而吹你的堆棧。

char line[LINE_LENGTH*N]; 

其中LINE_LENGTH是65537 * 6，N是10
