c++ - Garbage Value with cin.getline()

Question

My Aim: I am making a Course Management System. Here the query I am sharing is related to the component of the program that adds details about the new degree program user wishes to enter. Problem: I am using cin.getline() to take the input from the user as it also takes in space which I need to write the complete name of the program for example: Software Engineering. Therefore I cannot use cin >> here.

Terminal Output with Garbage Values

I understand it is because of the fact my array size id 50 and I am entering less characters that is why it is prining out garbage value. How should I solve it

void admin() {
system("CLS");
title();
char wish;
int i(1);
string buffer;
ofstream fbout;
ifstream fbin;
fbout.open("program.txt", ios::out | ios::app| ios::binary);
fbin.open("program.txt", ios::in | ios::binary);
program degree;
if (!fbout) {
    cerr << "Error in openning file" << endl;
    }
else{
    while (fbin.read((char*)&degree, sizeof(degree))) {
        
        cout << i <<". "<< degree.category <<" " <<degree.name <<" (" <<degree.callName << ")" << "" <<degree.school<<endl;
        i++;
    }
    cout << "Enter new program (Y/N)" << endl;
    cin >> wish;
    if (wish == 'Y') {
        cin.ignore(numeric_limits<streamsize>::max(), '
');
        cout << "Program Name : "; cin.getline(degree.name,50);
        cout << "School Name : "; cin.getline(degree.school,50);
        cout << "Degree Type : "; cin.getline(degree.category,50);
        cout << "Acronym : "; cin.getline(degree.callName,10);

        fbout.write((char*)&degree, sizeof(degree));
        fbout.close();
        admin();
    }
