so, all i have to do to use a c library is copy the *.c file into the directory where i have my .cpp and call it in the program with an #include "*.c" ?

i've inferred somewhere out there how to use fork() o c, but the program i'm running is in c++... so i would loooove to know if there is something similar in c++

i have to create a perent/children process in c++... is there any way to do it as in c?

did you try to run the program i posted? i mean, the second one... because when i run it, when it asks me for the first input (and by input i mean about data entry), i cannot see what i'm writing, and the program slows down completely... i don't know if it is because of the compiler i'm using (bloodshed dev-cpp) or what...
anyway, i'm still stuck in there...

thnx for your help. now, this library (windows.h) is completely new for me so i did what i understood was right, and the program runs almost to perfection...
i have already adapted the source code you gave me to my program. Though, now it presents a new problem... the inputs are not running like they should, i have turned all of the text to engish so you can understand what is the purpose of the program.

Hi...
I have been trying to figure this out, but it has been an impossible task 4 me...:rolleyes:
this is a gasoline pump counter, and i have developed an infinite cycle to print the gas counter and the cash counter...:mrgreen: the problem is, i need a stopper for the cycle, where the idea is that the user stops the flow of gas by pressing ENTER... but i'm done with trying everything to do this...:mad:
The lines are in spanish, but they are just junk...:cool:
Please help me... i'd really appreciate that...:)
Here's the code:
#include <iostream.h>
#include <stdio.h>
#include <conio.h>
#include <time.h>

float timer;
time_t seg, resta;
do{
cout<<"\n Bienvenido a la gasolinera LA GRAN ESTAFA\n";
cout<<"\n\nIngrese el tipo de carburante que desea dispensar\n\n-->";
cin>>carb;
comb=carb[0];
while (!((comb=='s')||(comb=='S')||(comb=='d')||(comb=='D')||(comb=='r')||(comb=='R'))){
cout<<"\n\nEl carburante ingresado es invalido\n\aPor favor ingreselo nuevamente\n\n-->";
cin>>carb;
comb=carb[0];
}do{
cout<<"Esta seguro que desea dispensar ";
if ((comb=='s')||(comb=='S')) printf("Super?\n\n-->");
if ((comb=='r')||(comb=='R')) printf("Regular?\n\n-->");
