$4]$ Write a program with an array of structures: Each structure should store: last name, first initial, GPA, and total number of credit hours taken by a student. $($Choose appropriate types for each!$)$ The array should be able to hold information for up to $100$ students. Initialize the first two array elements with the following info:o DoeJ $3\mathrm{.}5550$o Smith K $2\mathrm{.}8060$ Initialize the last array element with:o Aaaa B $3\mathrm{.}0570$ Display the three records above on the screen$\mathrm{.}7]$ Modify the program from #$4$ above $($array of structures$)$ by introducing a pointer to a stucture, named structPtr. Initialize structPtr to point to point to the first structure in the array. Print the first structure using structPtr instead of the array name. Move structPtr forward $($so it points to the second structure in the array$)$ usingo Array notationo Pointer notationWhich syntax is simpler? A: $\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_\_$Leave the simpler version in the code, and comment out the other. Print the second structure using structPtr instead of the array name.
