program help

[grunge man]

um i just starded macking a simple program and i want the user to input a number when it says enter a number then i want it to say that number *3 is, enter then the answer will appear here is what i have and i dont know whats wrong with it

#include
using namespace std;

int main(int argc, char **argv)

{
int k,n;
n = k*3;

cout << "type a number";
cout << k << "times three is";
cin>>n;
system ("pause"); /* execute M$-DOS' pause command */
return 0;
)

[Nedals]

n = k*3;
In this line, what are the values of n and k ?
Did you put that line in the right place?

You haven't even got the user input.

set up variables properly:

int k = 0;
int n = 0;

prompt the user:

cout << "type a freaking number --> ";

get the input

cin >> k;

multiply by three:

n = k*3;

then display the new result:

cout << endl << n;

o now i get it thanks yor trigering back my memory um but hey i have another question what does endl mean and what would happen if you put the values 4 to k and 5 to n

[grunge man]

also i changed it now and there is still errors here is the program curently and its errors i cant figure out how to correct the errors ok here bye the way i have a dev c++ compiler

#include
using namespace std;

int main(int argc, char **argv)

{
int k,n;
k = 0;
n = 0;
cout<<"type a number";
cin>>k;
n=k*3;
cout<

You haven't even got the user input.

set up variables properly:

int k = 0; int n = 0;

prompt the user: < "; <> k;

multiply by three: <

I don't think that compiles without errors?

Wow. Your stupidity becomes more prevalent with each post. I know you're still pissed about me letting you know how stupid your other post is, but that's not reason to carry over into someone elses thread. If you have a problem, then PM me and stop your fagish whining.

It's a joke my friend, I better stop becauseyour fagish whining is getting me and everyone else depressed.

Try this?

#include <iostream>
using namespace std;


int main()

{
int k,n;
k = 0;
n = 0;
cout<<"type a number";
cin>>k;
n=k*3;
cout<<endl<<n;

system ("pause"); /* execute M$-DOS' pause command */
return 0;
}

Okay children, stop the name calling!
grunge man, you forgot to iclude #include <cstdlib> // system()
#include <iostream> // cout, cin, endl

using namespace std;

int main()
{
int k, n;

cout<<"type a number: ";
cin >> k;
n = k*3;
cout << "\ntimes three = " << n << endl;

system("PAUSE");
return EXIT_SUCCESS; // optional with C++
}

[grunge man]

lol funny
Okay children, stop the name calling!
[/code] yep ene uran u are right but i figured that out b4 u replied by looking at the questions in the dev c++ help guide but hey thanks any ways um now my program looks like this

#include
using namespace std;
#include

int main(int argc, char **argv)

{
int k,n,d,e,l,y,t,o,m;
k = 0;
n = 0;
cout<<"type a number";
cin>>k;

n=k*3;
d=n*3;
e=d*3;
l=e*3;
y=l*3;
t=y*3;
o=t*3;
m=o*3;
cout<

Do you mind using code tags?

[grunge man]

what do u mean?

[SpS]

what do u mean?

Didn't I told you to read the rules before posting again. http://www.daniweb.com/techtalkforums/announcement8-2.html

[grunge man]

nvm i figured out what u were saying i read the second one but where would u use the code tags?

[Lerner]

use code tags anytime you are posting code to the board (or even text that you want to preserve indentation on as the board will eat it up otherwise)
