问题描述
有没有办法从一个函数返回一个数组?更具体地说,我创建了这个功能:
Is there any way to return an array from a function? More specifically, I've created this function:
char bin[8]; for(int i = 7; i >= 0; i--) { int ascii='a'; if(2^i-ascii >= 0) { bin[i]='1'; ascii=2^i-ascii; } else { bin[i]='0'; } }和我需要一种方法来返回斌[] 。
and I need a way to return bin[].
推荐答案您数组是在栈上分配局部变量。您应该使用新[] 分配它在堆上。然后,你可以说:收益斌; 。要注意的是,你必须与明确地释放它删除[] 当你用它做。
Your array is a local variable allocated on the stack. You should use new [] to allocate it on the heap. Then you can just say: return bin;. Beware that you will have to explicitly free it with delete [] when you are done with it.
