我開始磅=（INT **）...線大約堆是這樣得到錯誤：內存分配問題

「Windows已經引發了TestProj.exe一個斷點。

這可能是由於堆，這表明在TestProj.exe或任何它已加載的DLL的一個錯誤的損壞。

這也可能是由於用戶按F12而TestProj.exe有重點。

輸出窗口可能有更多診斷信息。「

你打F12了嗎？ – Pubby

你可以把你的問題歸結爲一個更簡短的例子嗎？ – arne

pi = (double*)calloc(MAXSTATES, sizeof(double*));

我想你應該有sizeof（double）不是指針，因爲它是一個double值的數組。

按如下方式分配內存可以避免在整個地方重複使用類型名稱，因此您不會錯配它。

double* pi = calloc(MAXSTATES, sizeof(*pi));

int **psi , i; 

    psi = malloc(MAXROWS * sizeof(int*)); 

    for(i = 0 ; i < MAXROWS ; i++) 
    { 
     psi[i] = calloc (MAXSTATES, sizeof(int)); 
    }

嘗試這樣做，和一個小檢查，如果PSI不爲空可能是巨大的^^。
