Shortest and longest string in array - arrays

Question

I have an assignment, I need to create a method that receives (char * * ch,site_t size).
ch is an array of addresses to char arrays, I need to make it so that the shortest element will be first (address and place) and longest will be last one (address and place). Here is what made so far although it doesn't work on array size 5 (tried only on size 4):
(Note: I used char * arr[] but I planned to changing it once I get the program working with this type of variable.)
void AdressSwitcher(char * arr[],size_t size){
char*shortest=arr[0];
char*shortestFollower=NULL;
char*longest=arr[1];
char*longestFollower=NULL;
for(size_t i=0;i<size;i++){
if(strlen(arr[i])<(strlen(shortest))){
shortest=arr[i];
arr[i]=arr[0];
}
arr[0]=shortest;
}
for(size_t i=1;i<size;i++){
if(strlen(arr[i])>(strlen(longest))){
longest=arr[i];
arr[i]=arr[size-1];
}
arr[size-1]=longest;
// }
for(size_t i=0;i<size;i++){
printf("%s %p", arr[i],arr[i]);
printf("\n");
}
}

Welcome to SO. This problem can be easily solved with the following method:
#include <stdio.h>
#include <string.h>
#include <stdlib.h>
char *escape_double_quotes(const char *s)
{
char *result = calloc((strlen(s) * 2) + 1, sizeof(char));
size_t resultIndex = 0;
for (size_t i = 0; s[i] != '\0'; i++)
{
if (s[i] == '"')
{
result[resultIndex] = '\\';
resultIndex++;
result[resultIndex] = '"';
resultIndex++;
continue;
}
result[resultIndex] = s[i];
resultIndex++;
}
return result;
}
void longestAndShortest(char **arr, const size_t size)
{
if (size <= 1)
return;
size_t shortIndex = 0;
size_t shortSize = strlen(arr[0]);
size_t longIndex;
size_t longSize = 0;
for (size_t i = 0; i < size; i++)
{
size_t b = strlen(arr[i]);
if (b > longSize)
{
longIndex = i;
longSize = b;
}
if (b < shortSize)
{
shortIndex = i;
shortSize = b;
}
}
printf("The shortest size of the array was %lu, the index of that being %lu and the contents of that being \"%s\".\n", shortSize, shortIndex, escape_double_quotes(arr[shortIndex]));
printf("The longest size of the array was %lu, the index of that being %lu and the contents of that being \"%s\".\n", longSize, longIndex, escape_double_quotes(arr[longIndex]));
return;
}
int main(void)
{
char **array = malloc(sizeof(char*) * 8);
array[0] = malloc(128);
strcpy(array[0], "World!");
array[1] = malloc(128);
strcpy(array[1], "Hello");
longestAndShortest(array, 2);
for (size_t i = 0; i < 2; i++)
free(array[i]);
free(array);
return 0;
}
From here you should be able to complete the rest.
Please work on writing more tidy code. Your future self will thank you.
Have a great day!
