我面臨的一個新問題,一些與內存分配和泄漏這裏是我的錯誤日誌:我的內存泄漏在C++程序

結構:
const int days=31;
const int exp=6;
struct Arr{
int days;
int exp;
int **M;
};
typedef Arr* Array;
構造:
void constr(Array &loc){
//Construct of 31*6 Matrix, were 31 nr. of days and 6 specific types:
//0-HouseKeeping, 1-Food, 2-Transport, 3-Clothing, 4-TelNet, 5-others
loc=new Arr;
loc->days = days;
loc->exp = exp;
loc->M = new int*[loc->days];
for(int i=0; i<loc->days;i++){
loc->M[i] = new int[loc->exp];
for (int j = 0; j < loc->exp; j++){
loc->M[i][j] = 0;
}
}
}
程序錯誤我只對一些功能ti例如功能:
void maxDay(Array &M){
//Output the day with highest value
cout<<"test";
int hD = 0;
int s1 = 0;
int s2 = 0;
cout<<"test";
for(int i = 0; i<30;i++){
s1=0;
for (int j=0; i<5; j++){
s1 = s1 + M->M[i][j];
if(s2 <= s1){
s2 = s1;
hD = i;
cout<<"test";
}
}
}
}
這麼短,我有一個結構Arr
(矩陣31 * 6)是我存儲整數(不同類型的開銷),但是當我使用我的一些函數時,我得到分段錯誤。我沒有這種錯誤的經驗,所以任何建議都很有用。
編輯:
void destruc(Array &loc){
for(int i=0; i<loc->days;i++){
delete[] loc->M[i];
for (int j = 0; j < loc->exp; j++){
delete[] loc->M[i][j];
}
}
}
我看到'new',而不是'delete'。 – Pubby 2012-04-04 04:12:01
我建議你用'std :: vector>'替換'int ** M'。實際上,有更好的方法,但這對現有解決方案影響最小。 –

事情是我必須使用我自己的結構:| – 2012-04-04 04:21:45
