初学c，squeeze(s1,s2)练习出错，请指导
squeeze（s1, s2),将字符串s1中任何以字符串s2中字符匹配的字符都删掉
#include <stdio.h>
void squeeze(char s1[], char s2[])
{
int i, j, k;
for (i = k = 0; s1[i] != '\0'; i++){
for (j = 0; s2[j] != '\0' && s2[j] != s1[j]; j++)
;
if (s2[j] == '\0')
s1[k++] = s1[i];
}
s1[k] = '\0';
}
main()
{
char s1[], s2[];
s1 = "1234567";
s2 = "345";
squeeze(s1, s2);
printf ("%s, %s" s1, s2);
}
出错显示

squeeze_12.c:18:7: error: array size missing in ‘s1’
