I'm trying to Write a program, to allow users to Enter Student Records into an Array and means of Selection Sort from the Array. I am trying to sort by the Student Number.

your program is only allowing you to enter one student, then you are sorting. That doesnt make sense because one element is sorted.

for (int n = 0; n < N_STUDENT;n++)
{
        cout <<"Enter Student Number: ";
        cin >> record[n].student_number

        cout << "Enter Studnet  Name: ";
        cin >> record[n].studnetname;
        
        cout << "Enter Student Address: ";
        cin >> record[n].Address;
        
        cout << "Enter Course Code: ";
        cin >> record[n].CourseCode;
        
        cout << "Enter Course Name: ";
        cin >> record[n].CourseName;
}

selectsort(record, N_STUDENT);


this will loop through an allow you to enter all the student info

void selectSort( int x[] int n); needs to be void selectSort( int x[], int n); in both places.

start with that...

thanks for all the reply s

i had the

               selectSort(n < N_STUDENT);
    for(n= 0; n < N_STUDENT; n++)
      cout << "X at pos" << student[n] << endl;


at the end of the main,
cout << "X at pos" << student[n] << endl;
should be allowing me to give out the Sorted Student ID.
When i had
cout << "Enter Course Code: ";
cin >> record[n].CourseCode;

Xcode was giving me errors since that was an int. so i had to use
getline (cin, mysrt1);
which seem to work but not was not declared in the array

The Loop is Working Well allowing me to add 10 Students,
just wondering i can i call the

void selectSort( int x[], int n);
inside the

   else if ( choice == 2)
        
        {
