How to implement gcc realtime output?

Question

C++ / C#

Let me explain the question with the simplest example.
Let's say I do a loop to display the percentage of completion in the console.
for (i = 0; i < n; i++)
{
if (i%(n/10) == 0) printf("%d ", i);
}
In Visual Studio, the percentage of completion is displayed in real time, in Code:Blocks under gcc on Unix, the result is displayed all immediately after the loop has completed. How to fix it?

If I understand your problem correctly, then you need to do fflush(stdout) after each printf
