Consider the following program, which calls a function to merge the given command line arguments $($except the program name$)$ as a dynamically created single string. It inserts $\text{'}$:$\text{'}$ as the separator between the command line arguments in the new string. Finally, the program prints the returned string and then frees it$.$If we run this program as$>$ prog aaaa bbbb cccIt should simply create the following string and print it asaaaa :bbbb:ccc

Match the correct code to each line to implement the abovementioned function that dynamically creates a new string by merging the given command line arguments and separating them with $\text{'}$ : $\text{'}$ You can use any standard library functions if needed.
