写出在母串中查找子串出现次数的代码

#include<stdio.h>

int count1(char* s1,  char* s2)

{

    int count = 0;

    while(*s1!=‘\0‘)

    {

        while(*s2 == *s1&&(*s2!=‘\0‘)&&(*s1!=‘\0‘))

        {

            s2++;

            s1++;

        }

        if(*s2 == ‘\0‘)

            count++;

        s1++;

    }

    return count;

}

main()

{

         char* s1="zhousenshan";

           char* s2="o";

printf("%d",count1(s1, s2));

}
