I have a .txt file named "COP1334C.txt" and it has this inside:

And the next thing under this message is my C++ code, for some reason it does not open the .txt file and I would like to know why exactly it does not open the file.

#include <iostream>
#include <fstream>
#include <string>

using namespace std;

int main() {
    int choice = 0;

    while (choice != 2) 
    {
        // Display menu
        cout << "Menu:\n";
        cout << "1. Process Grades Summary report\n";
        cout << "2. Quit\n";
        cout << "Enter your choice (1 or 2): ";
        cin >> choice;

        if (choice == 1) 
        {
            string fileName;
            cout << "Enter the name of the file (COP1334C.txt): ";
            cin >> fileName;

            ifstream inFile(fileName);
            if (!inFile.is_open()) 
            {
                cout << "Error: Unable to open file " << fileName << ".\n";
                continue;
            }

            string studentName;
            int grade;
            int totalGrade = 0;  // Sum of grades
            int highest = -1;    // Initialize to a value lower than any possible grade
            int lowest = 101;    // Initialize to a value higher than any possible grade
            int studentCount = 0;

            // Read student data from the file
            while (getline(inFile, studentName) && inFile >> grade) {
                inFile.ignore(); // Ignore newline character

                // Display student name and grade
                cout << studentName << "\t\t" << grade << "\n";

                // Sum grades
                totalGrade += grade;

                // Find highest and lowest grades
                if (grade > highest) {
                    highest = grade;
                }

                if (grade < lowest) {
                    lowest = grade;
                }

                // Count students
                ++studentCount;
            }

            inFile.close();

            // Display summary
            if (studentCount == 0) 
            {
                cout << "No student data found.\n";
            }
            else {
                // Calculate and display highest, lowest, and average grades
                double average = static_cast<double>(totalGrade) / studentCount;

                cout << "\nHighest Grade: " << highest << "\n";
                cout << "Lowest Grade: " << lowest << "\n";
                cout << "Average Grade: " << average << "\n\n";
            }
        }
        else if (choice != 2) {
            cout << "\nInvalid choice. Please enter 1 or 2.\n";
        }
    }

    cout << "\nExiting the program.\n Goodbye!\n";
    return 0;
}

I am expecting this output:
