Having an issue with my switch menu in a while loop - c++

Question

So I am working on a switch inside of a while loop. And it is not behaving properly. When I select 'l' and load the file it lets me select again, then when I try and press 'p' to print it, it just keeps looping over the selection prompt. I am pretty sure it is because choice != 'q', but don't know how to fix it.
Thank you for any help.
#include <iostream>
#include <fstream>
#include <string>

using namespace std;
//create a struct called Weather
struct Weather {
int month;
int date;
int high;
int avg;
int low;
double precip;
string event;
};
//function prototypes
int loadData(ifstream &file, Weather days[1000]);
void printData(Weather days[1000], int count);
int main() {
// declare variables
Weather days[1000];

string checker;
char choice = '0';
int month = 0, count;
string path;
cout << "Welcome to the weather analyzer!" << endl;
while (choice != 'q') {

cin >> choice;
cout << endl;
switch (choice) {
case 'l':
// promt user for file path

int i; //i varaiable keeps track of how many lines there are for the print function
for (i = 0; !inFile.eof(); i++) {
inFile >> days[i].date; // gets date and checks if it is 2017 with if loop
if (days[i].date == 2017) {
getline(inFile, checker);
getline(inFile, checker);
inFile >> days[i].date; //gets correct date value
month++;//increments month counter
}
days[i].month = month;//gets and stores data from file into days
inFile >> days[i].high

getline(inFile, days[i].event);
}
return i; //returns amount of days
}
// printing function
void printData(Weather days[1000], int count) {
for (int i = 0; i < count; i++) {
cout << days[i].month << " "

After reading the user input with cin, you probably want to flush the cin buffer:
cin.clear();
cin.ignore(INT_MAX);
