Hi, i have been given a task to do ar school that must read three strings in, store the third string in dynamically allocated memory and print out the last 4 letters of the first word alphabetically. Here is the program i have so far but the strings are all stored in different variables, making them hard to sort. if anyone could give me a hand and help me finish this program i would be very grateful. thanks

    #include <stdio.h>
#include <stdlib.h>
#include <string.h>

int main()
{
 char word1[101];
 char word2[101];
 char* word3;
 char buffer[101];
 scanf("%s", word1);
 scanf("%s", word2);
 scanf("%s", buffer);
 word3 = (char *) malloc(strlen(buffer)+1);
 strcpy(word3, buffer);




 return 0;
}
