Printf() and Scanf() functions are used for print the sentence in console and input any sentence or value in console respectively. While fread() and fwrite() are used for the file. So there is no common action or event between them. They are totally different things.

You are right. This is the perfect code for terminating input. You declared and throw exception at right time and proper place. There is no error. It will work well.

I think you have to manage CPU scheduling. It will help to improve the speed of execution.

I think you should recheck this part of your code. In that, there is some mistakes.
int maxSubseqSum(int seq[], int n);

int main(void)
{
int n, total;
ifstream fin("e.in");

assert(fin);

while (fin >> n) {
if (n == 0) break;

for (int i = 0; i < n; i++)
fin >> bet ;

total = maxSubseqSum ...
