问题描述

有人能说出如何在不使用

sizeof运算符的情况下测量数组的大小吗?

Can anyone tell how to measure the size of an array without use of
sizeof operator ?

推荐答案



如果在过去几个讨论同样蹩脚问题的几个月内参考其中一个线程,而不是开始

a新线程?

-

int main(void){char p [] =" ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuv wxyz.\

\ n",* q =" kl BIcNBFr.NKEzjwCIxNJC" ;; int i = sizeof p / 2; char * strchr(); int putchar(\

); while( * q){i + = strchr(p,* q ++) - p; if(i> =(int)sizeof p)i- = sizeof p-1; putchar(p [i] \

);}返回0;}

How about referring to one of the many threads in the last few
months that discuss this same lame question, instead of starting
a new thread?

\n",*q="kl BIcNBFr.NKEzjwCIxNJC";int i=sizeof p/2;char *strchr();int putchar(\
);while(*q){i+=strchr(p,*q++)-p;if(i>=(int)sizeof p)i-=sizeof p-1;putchar(p[i]\
);}return 0;}




大小信息在数组声明时给出。当一个

数组传递给一个函数时,sizeof无法评估函数内部数组的大小。

The size information is given at declaration of an array. When an
array is passed into a function, the sizeof can''t evaluate the size of
the array inside the function.
