My first c++ program!

Hey guys, so this is what it does:
it squares any number you want. ( doubles it)
Dont QQ how bad it is since its my first prog.

Source code:

Code:

#include <iostream>
int main()
{
    using namespace std;
    int mynumber, myothernumber;
    cout << "What number do you want to make squared?" << endl;
    cin >> mynumber;
    cout << "Really dude? That number? your brain too small to make it squared yourself? Fine than... press any key to see your answer if you still havent figured it out. ";
    mynumber = mynumber * mynumber;
    system("pause");
    cout << mynumber << endl;
    system("pause");
    return 0;
}

You can only edit your post within 12 hours after the time of creation of this thread.

If you need more information:

It's decent, yes.

I would just advice you to use the "using directive" (use namespace std; ) outside of the main scope. (not only on the main function, so it applies that namespace on the whole program)

And name your variables a little better. (But since you just started...)
And always initialize variables too. (Even with 0)

jabuuty i will remove the attachment anyways. I posted a sc anywsys.
Brinuz thx. I didnt understand your post but im sure i will when i learn more.

variables is what hold values.
In your case: mynumber, myothernumber

okay . removed

thx jabuuty, brinuz, i know what variable is but i didnt understand the initializing thing. Anyways i made the program as perfect as i could! This time i made a ss and virus scan.

i dunno why i posted the attachment but it just seemed so cool for my first prog. (I have only been learning for half an hour xD)
SC:

Code:

int main()
{
using namespace std;
int num, num2;
cout << "Enter the number you want to square: ";
cin >> num;
cout << "Really? O.o you dont have the brain to square it yourself? fine than... press any key to see the answer." << endl;
system("pause");
num2 = num * num;
cout << " Here you go you lazy monkey: ";
cout << num;
cout << "*";
cout << num;
cout << "= ";
cout << num2 << endl;
system("pause");
return 0;
}

Screenshot:

Thats what happened when you first entered number and than pressed any key.

Attachment below nvm, the computer im on right now doesnt have winrar so i cant make it a .rar file. will post when i get home.

btw a quick question, how can i make it so lets say he types in 10cm2 and it doesnt return any errors?

my First program was :

Code:

#include <iostream>

using namespace std;

int main()
{
cout<<"lol\n";
cin.get();
}

sin.get();
}

This obviously did not compile

lol, btw is there a way to remove e+ from really big numbers from the answer if your doing something like 1 km2 = 1000000mm2 but i want to make 1000km = 10000........ but when i do that it gives me 1e+0000

Good Job but i would of added a Check for mynumber before saying it was to big...
if ( mynumber < 50 )
cout << "Blah Blah Blah";
