I need help to complet this struct problem

here is the declaration for the struct

struct studentType
{
string name;
int credits;
float gpa;
string major;
char gender;
};
const int SIZE= 400;
studentType allStudents[SIZE];


1. I need to assign "Computer Science" as the major of all the students represented in array "allSudents"

2. write function definition of a value returning CountSophomore that counts the number of sophomore students in all the students. student considered sophomore if he has completed between 30-59 credits. the array allStudents and the number of students in the array are parameters of this function.

3. write complet definition of void function SwapStudents that exchanges the position of two students. the array "allSudents" and the index of the two students to be swapped are the parameters of this function

Explanation / Answer

Plz rate....

Note: This Program Runs Correctly on Borland Compiler and to Check the output of the program you should change the size of the array to 4 or 5 instead of 400 so that entry in the structure is easy, also Feel free to PM me if you have any problem in understanding.
