C$++$ please;

Assume the class Student has been declared and is structured as follows:

Three private members: a string field username, an unsigned long field id$,$ and a double field gpa.

A constructor that takes, in order, a string, an unsigned long, and a double parameter.

Write some code that initializes the variable students with an array of students. Assume the number of students has been assigned to the int constant NUMBER$\_$OF$\_$STUDENTS. The user should input the students' data one by one. Your code should not do input validation.

The format should follow carefully the example provided.

Sample Run $($Assume NUMBER$\_$OF$\_$STUDENTS is $2)$

Student #$1$ Username: student$\mathrm{.}1$

Student #$1$ Id: $11$

Student #$1$ Gpa: $2\mathrm{.}6$

Student #$2$ Username: student$\mathrm{.}2$

Student #$2$ Id: $925$

Student #$2$ Gpa: $1\mathrm{.}85$
