哪一个需要更少的内存？ [英] which one requires less memory?
问题描述
由于我们不想在计算字节数时出错，我们使用
代码
char * p;
...
p = malloc（strlen（" hello"）+ 1）;
strcpy（p，" hello"）;
而不是预期的
char * p;
...
p = malloc（ 6）;
strcpy（p，" hello"）;
i想要比较每个版本的内存要求：哪一个
需要更少的记忆？
Since we did not want to make an error in counting of bytes, we used
the code
char *p;
...
p = malloc(strlen("hello")+1);
strcpy(p,"hello");
instead of the intended
char *p;
...
p = malloc(6);
strcpy(p,"hello");
i want to compare the memory requirements of each version: which one
requires less memory?

您是否比较strlen（hello）+ 1到6？

Did you compare strlen("hello")+1 to 6?

是..
两者的评价都是6 ...但是这两个程序内部是否使用相同的内存？<
内存量？ br />
Yes..
Both evaluates to 6 ...but does these two programs internally use same
amount of memory?

请保留足够的上下文感觉。
当然他们这样做，他们都是malloc（6）。

Please retain enough context for your post to make sense.
Of course they do, they a both malloc(6).
