Answer in C language, add comments to code, three files included main.c, Stringstr.c, Stringstr.h each file indicated in bold, NOTE: Must be a deep copy

Provide screenshot of implemented code and output, task description located in main

/* Add an append function for the StringString object . Functions already implemented : Create, Delete, printing

Add the implementation for a function void SStr_Append(SSTRING* str, SSTRING* str_to_append)

The first argument is the string that will be appended to. The second argument is the string to append.

For example, // str1 contains "Chocolate" // str2 contains "Cookie" SStr_Append(str1, str2); // str1 now contains "Chocolatecookie"

NOTE: deep copy of the str_to_append */
