Runtime check

[fernandofranca]

The code runs perfectly, but when I press any button, for continuing the system Pause, it gives the error:

You need to break things into functions so its more readable. Also try this :

while (arquivo && getline(arquivo, arquivo_linha))

Same error =(

[fernandofranca]

The error was being caused because the double vector is limited with four positions, so it doesn´t have the null terminator,
after declarint

double parm[5]; it worked fine =)

Thanks!
