Objective

In this challenge, you will write a program that concatenates two strings provided by arguments $1$ and $2$

Program Overview

Create a function that concatenates $2$ c$-$strings.

Pass arg$1$ and arg$2$ to the new function

Print out the concatenated strings

Steps to complete

Copy the string$\_$length function from level $1,$ by using cat on the main.c from the prior level, which is located at $../01/$main$.$c

Follow the CODE: instructions provided in main.c

Write a user test that tests the program's length function $($user$\_$tests$/$utest$3\mathrm{.}2.$json$)$

To use a double quote in the test case, it must be escaped, "which is done like $\backslash "$this$\backslash "."$

Run $/$challenge$/$tester to get the flag
