Q$3)(26$ pts$.)$ Write a $C++$ function to Bet $4$ strings as character pointers as input parameters as follows:

String$1$: first name

String$2$: middle name

String$3$:sumame

String$4$: outputstring firstname$-$middlename$-$surname sequence, If the optlon is $0$ the output string should have surnamemiddiename$-$firstname sequence, As if the option is different than o and $1,$ it should conv notavallable" to output string.

Q$4)(30$ pts$.)$ Consider the following structure:

struct stdi

int id;

char name$[30]$:

Istd$\_$array$[100]$:

Write a somplete $\frac{C}{C}++$ program that opens the files Iid,tit" and "name.txt$"$ that includes id's and names of the students. The program should load from the files to the array of structures, given above as std array. Then, the program should print the id's and names of the corresponding students to the output file "studentinfo.txt$".$

Ex:

$\backslash$table$[[$Id$.txt$
