getline isn't allowing input

[loganc123]

Hello! In my statement, if (userChoice == 'S'), the getline statement should be prompting the user for input asking for the students name, however it seems to automatically grab some data for this rather than prompting the user for input. Is there something I'm doing wrong here?

  #include "stdafx.h"
#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <cmath>

using namespace std;
struct myCourses //This struct in inside the one below it
{
	string myClass;
};

struct Records	//struct definition
{
	string name;
	int numCourses;
	myCourses courseCode[6];
};

int search(Records inventory[], string name, int size);
ifstream fin;

int main()
{
	fin.open("courses.txt");
	int size = 0; //size of dynamic array
	int count = 0; //counter for index
	char userChoice;

	fin >> size; //returns the first line of the document containing array size (12)
	Records* student = new Records[size]; //Dynamic allocation of array

	while (count < size) {						 //while array is not filled and file status is good, read/store the following:
		fin.ignore(1000, '\n');					 //clears buffer and ready for next line of text
		getline(fin, student[count].name, '\n'); //stops when it finds end of line

		fin >> student[count].numCourses;	     //reads in # of classes (keep simple)

		for (int ndx = 0; ndx < student[count].numCourses; ndx++)  //uses for loop to insert classes for student	
			fin >> student[count].courseCode[ndx].myClass;

		count++;
	}
	fin.close();

	cout << "Enter menu choice or Q to quit:" << endl << "D to display all students and courses" << endl << "S to display courses for a student" << endl << "C to display students taking a course" << endl << endl << endl;
	cin >> userChoice; //Prompts the user for their choice, while not "Q", do the following

	while (userChoice != 'Q') {
		if (userChoice == 'D') {		//display all students and courses
			cout << left;
			for (int i = 0; i < size; i++)
			{
				cout << setw(20) << student[i].name;

				for (int x = 0; x < student[i].numCourses; x++)
					cout << student[i].courseCode[x].myClass << " ";

				cout << endl;
			}
		}
		cout << endl << "Enter next choice: ";
		cin >> userChoice;

			getline(cin, theName, '\n');
			spotInArray = search(student, theName, count);
			cout << theName << " is taking: " << student[spotInArray].courseCode << endl;

			cout << endl << "Enter next choice: ";
			cin >> userChoice;
		}

		if (userChoice == 'C') {		//display all students enrolled in a class
			string theCourse;
			cout << "Enter course name: ";
			cin >> theCourse;
		}
	}

int search(Records record[], string name, int size) {

	for (int i = 0; i < size; i++)
		if (record[i].name == name)
			loc = i;
	return loc;
}

I fixed your problem with the input,now the input should work

the problem is that a /n is still left in the buffer from cin with the >> operator and when you call getline it consumes that /n basically giving you an empty string,what I did was I used cin.get() to get the \n character,

that should solve that problem but I don't think the program is finished

#include <iostream>
#include <iomanip>
#include <fstream>
#include <string>
#include <cmath>

using namespace std;
struct myCourses //This struct in inside the one below it
{
	string myClass;
};

struct Records	//struct definition
{
	string name;
	int numCourses;
	myCourses courseCode[6];
};

int search(Records inventory[], string name, int size);
ifstream fin;

int main()
{
	fin.open("courses.txt");
	int size = 0; //size of dynamic array
	int count = 0; //counter for index
	char userChoice;

	fin >> size; //returns the first line of the document containing array size (12)
	Records* student = new Records[size]; //Dynamic allocation of array

	while (count < size) {						 //while array is not filled and file status is good, read/store the following:
		fin.ignore(1000, '\n');					 //clears buffer and ready for next line of text
		getline(fin, student[count].name, '\n'); //stops when it finds end of line

		fin >> student[count].numCourses;	     //reads in # of classes (keep simple)

		for (int ndx = 0; ndx < student[count].numCourses; ndx++)  //uses for loop to insert classes for student
			fin >> student[count].courseCode[ndx].myClass;

		count++;
	}
	fin.close();

	cout << "Enter menu choice or Q to quit:" << endl << "D to display all students and courses" << endl << "S to display courses for a student" << endl << "C to display students taking a course" << endl << endl << endl;
	cin >> userChoice; //Prompts the user for their choice, while not "Q", do the following

	while (userChoice != 'Q') {
		if (userChoice == 'D') {		//display all students and courses
			cout << left;
			for (int i = 0; i < size; i++)
			{
				cout << setw(20) << student[i].name;

				for (int x = 0; x < student[i].numCourses; x++)
					cout << student[i].courseCode[x].myClass << " ";

				cout << endl;
			}
		}
		cout << endl << "Enter next choice: ";
		cin >> userChoice;
		if (userChoice == 'S') {		//display the courses a student is taking
			int spotInArray;
			string theName;
			cout << "Enter student name: " << endl;
			cin.get();
			getline(cin, theName, '\n');
			spotInArray = search(student, theName, count);
			cout << theName << " is taking: " << student[spotInArray].courseCode << endl;

			cout << endl << "Enter next choice: ";
			cin >> userChoice;
			cin.get();
		}

		if (userChoice == 'C') {		//display all students enrolled in a class
			string theCourse;
			cout << "Enter course name: ";
			cin >> theCourse;
			cin.get();
		}
	}


}


int search(Records record[], string name, int size) {
	int loc = -1;
	for (int i = 0; i < size; i++)
		if (record[i].name == name)
			loc = i;
	return loc;
}

PS cin.clear() isn't doing what you think its doing
