Requirement: Use pointer pointer to output string. You first use a pointer array to create an array of strings, and then define a pointer pointer to the string array and use the string in its output array. At the same time, the contents of the array are sorted in ascending order.

#include <stdio.h>

#include <string.h>

void Ascsort (char **arr,int len)//Receive pointer type array, and length

{

for (int i=0;i<len-1;i++)

{

for (int j=0;j<len-1-i;j++)

{

if (strcmp (arr[j],arr[j+1]) >0)//Ascending sort

{

Char *temp = arr[j];

ARR[J] = arr[j+1];

ARR[J+1] = temp;

}

}

}

}

void PrintArray (char* arr[],int Len,char **p)

{

for (int i=0;i<4;i++)

{

printf ("%s", * (P+i));

}

printf ("\ n");

}

int main (int argc, const char * argv[])

{

char* str[]={"Jony", "Tom", "Smith", "Boy"}; //array of pointer types

Char **p;//defines pointer variables that point to pointers

p = str;

printf ("Before sorting:");

PrintArray (STR,4,P);

Ascsort (str,4);

printf ("After sorting:");

PrintArray (STR,4,P);

return 0;
