为什么在职能之后,某个点人所分配的记忆继续存在,但不是阵列?
原标题:Why does a pointer s allocated memory persist after a function, but not an array?

因此,在基本案文投入职能方面,我提出这个问题,见C++书:

char *getString()
{
    char temp[80];
    cin >> temp;
    char * pn = new char[strlen(temp + 1)];
    strcpy(pn, temp);
    return pn;
}

因此,温室宣布有80个果园,即一个自动变数,其记忆将在<条码>植被(回归后释放。 据悉,如果你出于某种原因返回<代码>temp,则在职能之外使用该密码是不可靠的,因为这一记忆在功能完成后即被释放。 但是,由于Im还宣布pn<>pn>/code>,因此,其记忆如何也没有得到抛弃?

问题回答

由于你标有<代码>新的物体在跃式上分配,而诸如<代码>temp等变数则在栏目上。

当你恢复职务时,其分界线被分配,但差距不大。
