问题描述
以下实际上是模式匹配程序的一部分
i尝试过，memset没有用
-1
#include< string.h>
#include< stdio.h>
#include< stdlib.h>
int main（无效）
{
int maxpat [80];
memset（maxpat，-1,80）;
for（i = 0; i< 80; i ++）
printf（"％d \ t"，maxpat [i]）;
返回EXIT_SUCCESS;
}
但是我得到了o / p
-1 -1 -1 -1 -1 -1 -1 -1
-1 -1
-1 -1 -1 -1 -1 -1 -1 -1
-1 -1

Hi,
the following is actually a part of the pattern matching program which
i tried ,memset is not setting the entire integer array with
-1
#include <string.h>
#include <stdio.h>
#include <stdlib.h>
int main(void)
{
int maxpat[80];
memset(maxpat,-1,80);
for(i=0;i<80;i++)
printf("%d\t",maxpat[i]);
return EXIT_SUCCESS;
}
but i am getting o/p as
-1 -1 -1 -1 -1 -1 -1 -1
-1 -1
-1 -1 -1 -1 -1 -1 -1 -1
-1 -1

why is this so..????
推荐答案
抱歉，我忘了申报i，但o / p仍然相同
sorry I forgot to declare i, but still the o/p is same
您只设置数组的前80个字节，而不是80个整数。 br />

You are only setting the first 80 bytes of the the array, not 80 ints.
