Problem with Functions!

Code:

---

#include <iostream.h>

int x;
void input();
int main()
{
      input();
      cout << x;
      return 0;
}

void input()
{
        cin >> x;
        cout << x;
}

Is this what you are trying to accomplish?
If so, it works when compiled under visual C++...

it has to be set up like this

struct

inputFunction()

randomFunction()

outputFunction()

main()

Every variable must be sent to the structure and then retrieved from it

I am posting this because you did not use code tags on this thread. In the furture please use Code Tags. They make your code MUCH easier to read and people will be much more likely to help you if you do. And they'll be happier about helping you ;)

For example:

Without code tags:

for(int i=0;i<5;i++)
{
cout << "No code tags are bad";
}

With Code Tags:

Code:

---

for(int i=0;i<5;i++)
{
    cout << "This code is easy to read";
}

---

This is of course a basic example...more complicated code is even easier to read with code tags than without.

I've added code tags for you this time. They can be added by putting [code] at the beginning of your code and [/code] at the end. More information on code tags may be found on the code tag post at the top of every forum. I also suggest you take a look at the board guildlines if you have not done so already.

This is a common first post mistake, just remember to use [code] tags in the future and you'll get much more help.

If this is your first time posting here the welcome, and if there's anything I can do or any questions I can answer about these forums, or anything else, please feel free and welcome to PM me.


Good Luck with your program,

that was very nice kermi3 but why not give my problem a go?

Kermi: lol, haha, i forgot to type them in. I am new but I DID read your sticky...Thanks for doing it for me.

Is this what you're looking for?

Code:

---

#include<iostream.h>
#include<iomanip.h>
#include<conio.h>
#include<string.h>
#include<math.h>
#include<time.h>
#include<stdlib.h>

struct info
{
        int number;
};


void input(info& vars)
{
        cout<<"Enter a number: ";
        cin>>vars.number;
        /******************************************
                      IT WORKS HERE
        ******************************************/
        cout<<vars.number;
}

main()
{
        info vars;
        input(vars);
        cout<<endl;
        /******************************************
                      BUT NOT HERE
        ******************************************/
        cout<<vars.number;
        getch();
}

Sorry for doing the code tags wrong. But the code above should work for you now. The change is the:

Code:

---


void input(info& vars)

yes finally thank you!
