我试图做二维动态字符串数组，并取得了一些成功，但由于某种原因，两个int变量，实际上是行数（指针数组）和字符串的大小（它们可以有多长），变成了一个神秘的值。

#include <stdio.h>
#include <stdlib.h>
#include <math.h>
#include <time.h>

void write (char ***p, int size_r, int size_c)
{
    int i;
    for (i = 0; i < size_r; i++)
    {
        printf("%s", p[i]);
    }
    return;
}

void arr_of_p (char*** p, int size_r, int size_c)
{
    int i;
    for (i = 0; i < size_r; i++)
    {
        p[i] = "helo\n";
    }
    return;
}


int main(void)
{
    int string_n; printf("How many strings: "); scanf("%d", &string_n);
    int string_l; printf("How long are the strings: "); scanf("%d", &string_l); 

    char **s_p = (char**) malloc(string_n*sizeof(char*));
    int i;
    for (i = 0; i < string_n; i++)
    {
        s_p[i] = (char*) malloc(string_l*sizeof(char));

    }
    arr_of_p(&s_p, string_n, string_l);
    printf("%d\n%d\n", string_n, string_l); // for debugging purpose, add breakpoint here. 
                                           //"string_n" and "string_l" will be identical to the value of "i" in "arr_of_p()" for some reason... 
    write(&s_p, string_n, string_l);
    return 0;
}
