error: expected ‘}’ at end of input -- when there is one [closed]

Question

I am getting this error when compiling:

project6.cpp: In function ‘int main()’:

project6.cpp:187: error: expected ‘}’ at end of input

However, there is clearly an end bracket to my int main () function at that line, so I am confused as to why I am getting this error. I also checked all of my other brackets and found none that were not closed. Any help would be much appreciated!

#include <iostream>

Answer 1

One of your else blocks does not have a closing brace... Look below:

     else
     {  cout << "Crashed after " << i << " seconds" << endl;
     printRace(grid);
     i = 500;

Due to this, the total number of closing braces is not equal to the opening braces, hence the error.
