模拟实现库函数strstr

模拟实现库函数strstr
代码如下

#include<stdio.h>
const char* mystrstr(const char*src, const char *needle)
{

    for (int i = 0; src[i] != '\0'; i++)
    {
        int temp = i;
        int j = 0;
        while (src[i] == needle[j])
        {
            i++;
            j++;
            if (needle[j] == '\0')
            {
                return &needle[temp];
            }

        }
        i = temp;
    }
    return NULL;
}
int main()
{
    char arr[] = "aaaaabcdaaa";
    char brr[] = "abdc";
    const char *s=mystrstr(arr, brr);
    printf("%s", s);
    system("pause");
}
