测试_StringFind_IntArrFind

需求:

1000000个数, 

存在char*里strstr("9999,")　　快?  

存在IntArr里for循环查找　　快?

void testarr_init(int testnum, int **intarr, char **stringarr)
{
    *intarr        =    (int *)calloc(testnum, sizeof(int));
    *stringarr     =    (char *)calloc(testnum, sizeof(char)*8);

    int *pIntarr    =    *intarr;

    char temp[16];

    for (int i= 0; i< testnum; i++)
    {
        *pIntarr++    =    i;

        itoa(i, temp, 10);
        strcat(temp, ",");
        strcat(*stringarr, temp);
    }
}

void compare_intarr_string_find()
{
    int testnum        =    100000;

    int *intarr_head;
    char *stringarr_head;

    testarr_init(testnum, &intarr_head, &stringarr_head);

    int iKey    = intarr_find(99999, intarr_head, testnum);
    char *pKey    = string_find("99999,", stringarr_head);

    printf("%d\n", intarr_head[iKey]);
    printf("%s\n", pKey);

    free(stringarr_head);
    free(intarr_head);
}

结论:

intarr查找较快.
