C ++新&删除和功能 [英] C++ new & delete and functions

问题描述

这有点不清楚我...所以，如果我有一个函数：

This is a bit unclear to me... So, if I have a function:

char *test(int ran){
    char *ret = new char[ran];
    // process...
    return ret;
}

，然后多次调用：

for(int i = 0; i < 100000000; i++){
   char *str = test(rand()%10000000+10000000);
   // process...

   // delete[] str; // do i have to delete it here?
}

$ b <

推荐答案

您不有。但是如果你不删除内存你保留与'新'，你将开始运行内存最终（内存泄漏）。

You don't have to. But if you don't delete memory you reserved with 'new' you will start running out of memory eventually (memory leak).
