Help Please !!!!!!!!

:confused:

I am on the second part of the Tutorial on cpprogramming.com
and i tried the age program

Code:

---

#include <iostream.h>                       
                       
int main()                                //Most important part of the program!
{
  int age;                                //Need a variable...
 
  cout<<"Please input your age: ";        //Asks for age
  cin>>age;                                //The input is put in age
 
  if(age<100)                                //If the age is less than 100
  {
    cout<<"You are pretty young!";    //Just to show it works
  }
  else if(age==100)                //I use else just to show an example
  {
    cout<<"You are old";                //Just to show you it works...
  }
  else if(age>100)
  {
    cout<<"You are really old";        //Proof that it works for any condition
  }
  return 0;
}

---

I am using DEV-C++ Ver 4.9.9.1
and when ever i compile and run , a command screen pops up but when i enter the age and press ENTER it exits HELP please :confused:

nothing is working i even downloaded a chess game from one of the Threads but every time i try to run it , a black screen pops up and disappears really fast. :confused: HELP!!!!

it's not great programming using system, but can be useful when your starting out:
system ( "pause" ) ;
before you return, this runs "pause" through cmd.exe

i didnt really understand what you just said i am Newbie so you going to have to speak in details.thanks

OK NM i will try

THANK YOU SO MUCH YOU JUST MADE MY DAY

:D

COOLLLLLLLLL
Now i can continue the TUTORIAL. thanks again

You're program is working just fine, it's just that it displays its output and then exits so fast that you don't get a chance to read anything. Using system("pause") might work but a better alternative would probably be to put:

Code:

---

cin.get();

---

right before the return statement.

Thanks i was about the ask for help again

Code:

---

#include <iostream.h>

int mult(int x, int y);

int main()
{
  int x, y;
  cout<<"Please input two numbers to be multiplied: ";
  cin>>x>>y;
  cout<<"The product of your two numbers is "<<mult(x, y);
  return 0;
}

int mult(int x, int y)
{
  cin.get();
  return x*y;
}

---

Okay how do i work that program i tried typing a # then Pressing ENTER then typing another one then ENTER again < after that it just exits :confused:

Here is my answer to the multiplication program:

Code:

---

#include <iostream> //use iostream not iostream.h
using namespace std;//include this so you will be able to use cout not std::cout

int main()
{
  int num1,num2,answer;
 
 
  cout<<"Please input a number to be multiplied: " << endl;
  cin>>num1;
  cout << "Please input a second number to be multiplied:" << endl;
  cin >>num2;
  answer=num1*num2;
  cout<<"The product of your two numbers is " << answer << endl;
  system("PAUSE");
  cin.get();
  return 0;
}

the cin.get() is in the wrong place.. its suppose to be in the main function...
and put cin.ignore() after it..

Yours seem to work thanks
and i also made a Division version of that one .
^ i know its not that impressing but hey i started reading that tutorial today i didnt Know nothing about c++ before and i am only 15 years old and i am trying to absorb everything that is tought in that tutorial . THANKS again for all your help.

if you are going to be using system("PAUSE"); no need for cin.get().. :rolleyes:

It worked both ways but i understand that it is not needed

Code:

---

struct database
{
  int id_number;
  int age;
  float salary;
};

int main()
{
  database employee;  //There is now an employee variable that has modifiable
                            //variables inside it.
  employee.age=22;
  employee.id_number=1;
  employee.salary=12000.21;   
  return 0;
}

---

I need help again its show up and disappearing right away.
I tried using system("pause");AND ther other one. but its given me an error. "SYSTEM" UNDECLARED

HELP :confused:

#include <iostream>
using namspace std;

---

cin.ignore(); then cin.get();

First clear the stream.

Put this at the beginning of your program:

Code:

---

#include <iostream>
using namspace std;

---

Including iostream allows you to use cin and cout (input and output). The 'using namespace std' part is the block of code named std that cin and cout are located, but dont worry about that yet.

Then at the point you want it to pause (usually at the end of the program) put:

Code:

---

cin.ignore();
cin.get();

---

This leaves you with:

Code:

---

#include <iostream>
using namspace std;

struct database
{
  int id_number;
  int age;
  float salary;
};

int main()
{
  database employee;  /* There is now an object of the 'database' that allows you to edit the
variables inside of it, named employee. Object meaning a copy of it. */

  employee.age=22;
  employee.id_number=1;
  employee.salary=12000.21;   

  cin.ignore();
  cin.get();

  return 0;
}

---

Place those two together wherever you want to pause, I would forget about SYSTEM pause, but if you prefer to use it while learning its cool.

Oh by the way you seem to be going a little fast.. you might want to re-read the tutorials, take the quiz, and maybe try a few other site tutorials in order to get all the concepts. Tutorials are nothing compared to the depth and clarity taught in the books, so if youre only following a tutorial you may have to work harder and search around.

I am only 15 too. I've been going off the tutorials on this site for a little while, but got bored of them. So I switched to reading books, it's a lot more reliable, and informative. I am using C++ for dummies. It is quite good, but seems like it requires you to know a little C++ already. I just posted that code since it was the easiest to use and works with most of the mathmatical operations. Yours was a little too confusing, and didn't make much sense. I usually do things the easy way, but people end up making fun of my code. :rolleyes:

Just don't keep going off of other peoples examples, too much. In programming there is no set way of doing things, which makes it so fun. I made the mistake of basing my programs off of other peoples programs, and it started to become boring for awhile. Just remember, there is more than one way to make a program. If it doesn't work, just keep changing, and compiling, works for me:)

like others have said, forget about system. try to avoid it like the plague. if you need a pause at the end of your program, just use this:

Code:

---

int main()
{
    ...
    std::cin.get();
    return 0;
}

---

no need to use std::cin.ignore(1); there because you don't need the stream anymore, so there's no use in keeping it clean.

the reason your compiler is complaining about system() is because it's in <cstdlib>, so you'd need to include that too.
