guys i need help aswell ROFL. i just started c++ and this is wat i got.
| Code: | #include <iostream.h>
#include <string.h>
void main ()
{
char name[8];
short cost;
float amount;
float totalsale;
cout << "Name of the customer: ";
cin.getline(name, 8);
cout << "What does it cost: ";
cin >> cost;
cout << "What is the amount: ";
cin >> amount;
totalsale = (float)amount * (float)cost;
cout << endl;
cout << "Customer name: " << name << endl;
cout << "The amount wanted: " << amount << endl;
cout << "The cost of the item is: " << cost << endl;
cout << "The total sale is: $" << totalsale << endl;
} |
i dont get wat void main () is suppose to do
and and | Code: | char name[8] = " ";
short cost = 0;
float amount = 0.0;
float totalsale = 0.0;
char name[8];
short cost;
float amount;
float totalsale; |
whats the difference between these two codes?

void main() is the entry point of your program. (Console app.) It is the first thing to be called when its loaded. Without an entry point, your program will not do anything, and in most cases wont compile.
It is also suggested not to use void for the entry point but instead to use a returning type such as int or boolean.
| Code: | int main()
{
// your code here
} |

Well.. Wiccan answered the first part, I'll answer the second one; The first one initializes the variables with "reasonable" values, whereas the later one doesn't. If you try printing those last ones, you'll probably get some random values, like 1234... Print them and you will see.

My bad, too many C programming habits.
You know what I was getting at though. |

I don't remember windows having it's own sleep function inside iostream.. Isn't that only on linux?

sleep is linux (lowercase s, seconds, unistd.h)
Sleep is windows(uppercase s, milliseconds, winbase.h  )

Sleep for Windows is located in winbase.h just fyi. Auto included if you include windows.h if you need everything.
