I'm writing a program that makes huge amounts of calculations without user's interference.
So I wrote in the code some printf() just to know when it's doing what.
For example, when it's going to read some big matrix from a file, it was suposed to print on screen something like "Reading the matrix", but it don't really happen.
It prints everything at the end...
My question is: why those printf commands that comes before in the code runs after?
