I have a bug in my code I can't figure out. The bolded part is supposed to loop back to asking for the size of a vector if a non-integer is the input, and to the end if q or Q is for "quit". The code is working except for the q/Q part, when I input q/Q the output is the same as the other cin.fail() non-integer options where it asks for the vector size again, instead of jumping to the end of the main function and exiting. I have included the lab7functions.cpp below the main function if you want to test program but that is working fine.

#include

#include "lab7functions.h"

using namespace std;

int main()

{

int size;

int item;

while (true)

{

cout << "Please enter the size of the sequence (type 'Q' or 'q' to quit): " << endl;

cin >> size;

cin.ignore(256, ' '); // get rid of either 256 characters or till reach the end of line, which comes first

// check if the user input is not valid

// your code starts here...

if (cin.fail())

{

char quit;

cin >> quit;

if ((quit == 'q')||(quit == 'Q'))

{

cout << "test" << endl;

break;

}

else

{

cin.clear();

cin.ignore(256, ' ');

cout << "Invalid input, please try again..." << endl;

continue;

}

}

// valid user input size, store into the vector

vector nums;

srand(time(0));

for (int i = 0; i < size; i++)

{

item = rand() % RANGE + 1; // each item is in the range of [1, RANGE]

cout << "Inserting..." << item << endl;

insertAtFront(nums, item);

cout << "The sequence: " << endl;

for (int i = 0; i < nums.size(); i++)

cout << nums[i] << " " ;

cout << endl;

}

// calculate the length of the longest run in the vector created above

int length = run_length(nums);

cout << "The run length of the sequence is: " << length << endl;

}

cout << "Thank you. Bye..." << endl;

return 0;

}
