what is wrong with this code?

#include <iostream>

    // add course to array
    Course course;
    course.courseCode = courseCode;
    course.creditHours = creditHours;

}

The issue with this code is that the cout statements in lines 12, 15, 18, 21, and 24 are missing the insertion operator (<<) before the string being output. They should be written as "cout << "Enter student ID: ";" instead of "cout ​0
Invalid citation
oaicite:{"index":0,"invalid_reason":"Malformed citation << "Enter student ID: ";\n cin >>"}​"}​ studentID;". The same applies to the other similar lines. This will prevent a compilation error and allow the program to run properly.
