squeeze函数编写

#include <stdio.h>#include <stdlib.h>//编写squeeze函数（s1，s2），将字符串s1中任何与s2中字符匹配的字符都删除int test(char ch,char s2[]);void squeeze(char s1[],char s2[]);int main(){    char s1[] = {'a','b','2','3','5','d','\0'};    char s2[] = {'1','2','3','4','5','6','7','8','9','0','\0'};    squeeze(s1,s2);    //printf("%d",test('3',s2));    printf("%s",s1);    return 0;}void squeeze(char s1[],char s2[]){    int i,j;    for(i = j= 0;s1[i] != '\0';i++)        if(!test(s1[i],s2))            s1[j++] = s1[i];    s1[j] = '\0';}//用于监测某个char型变量是否包含在另一个char型数组中int test(char ch,char s2[]){    int i ,n = 0;    for(i = 0; s2[i] != '\0'; i ++)        if(ch == s2[i])        {            n = 1;            break;        }    return n;}
