请帮我解决内存损坏问题 [英] Please help me in memory corruption

问题描述

我有一个函数，其中使用new分配内存但未删除。功能如下：


void AddItem（char * buffer，char * items []，int& index）

{

char * temp = new char [strlen（buffer）+ 1];


strcpy（temp，buffer）;


items [ index] = temp;


index ++;

}


此函数AddItem（）被调用52次程序内部。

然后我认为这会导致一些内存问题或者它会减慢程序的速度。请让我知道我可采取哪些纠正措施。

谢谢。

在你的函数中使用它

在函数中使用此函数

展开 | 选择 | Wra p | 行号

< blockquote>

但是这里它将temp复制到item [index]。

如果我将删除函数内部的temp，它会将内存松散到item [index] ]。

请告诉我。

I have a function in which memory has been allocated using new and not being deleted. The function is as below:

void AddItem(char* buffer, char* items[], int& index)
{
char* temp = new char[strlen(buffer) + 1];

strcpy(temp, buffer);

items[index] = temp;

index++;
}

This function AddItem() has been called 52 times inside the program.
Then I think this is causing some memory issue or its slowing down the program. Please let me know what corrective action can I take.
Thanks.

Use this in your function

But here its copying temp to item[index].
if I will delete temp inside the function it will loose the memory to item[index].
Please let me know.
