When given input, my while loops print one time extra before closing its loop. For example, 8 7 38 3 -5 -1 q is my input that prints out

Provide 6 integer coefficients for the brute force equation solver:
Solution found: x = 3, y = 2

Run program again? Type 'q' to quit or any other key to continue:

When it should end after the first iteration. Can anyone help me out on this? My code is pasted below

```
#include <stdio.h>
#include <math.h>
#include <stdbool.h>

int main(void) 
{
   //Equations should be a1x + b1y = c2 and a2x + b2y = c2
   int a1, b1, c1, a2, b2, c2, x, y;
   char input;
   bool solFound = false;
   bool runAgain = true;

   //brute force x and y [-10, 10]
   while (runAgain == true) 
   {
      printf("Provide 6 integer coefficients for the brute force equation solver: ");
      scanf("%d %d %d %d %d %d", &a1, &b1, &c1, &a2, &b2, &c2);
      for (x = -10; x<=10; x++)
      {
         for (y = -10; y<=10; y++)
         {
            if (a1*x + b1*y == c1 && a2*x + b2*y == c2)
            {
                  printf("\nSolution found: x = %d, y = %d\n\n", x, y);
                  solFound = true;
                  runAgain = false;
            }
         }
      }
      if (solFound != true)
      {
         printf("No solution found\n\n");
         runAgain = false;
      }
      scanf("%c", &input);
      printf("Run program again? Type 'q' to quit or any other key to continue:");
      if (input != 'q')
      {
         runAgain = true;
      }
      printf("\n\n");
   }
} ```
