Trying to do Matrixy Text in C++

[Sam-U-Rai]

While we were doing loop demos in class (HS C++ Half-year course), me and my friend found that if you set the loop number (middle section) to more than a couple thousand, it'll keep running text over the screen up and down.


Well, I was just trying to do this at home and Idk if I did it right. It'll just print it once. The main thing I'm getting at is that I want a constant flow of numbers and letters just for kicks to look cool.


Here's the code I just made in Visual C++:
I think I got some of the Loop code wrong. Help me out if you can guys .

#include(Iostream Library in C++, Forum won't show)
#include(Iomanip.h Library in C++, Forums won't show)

int main (void)
{
int x;

{
for (x=1 ; x>=2000000; x+=1);

cout<<"1 2 3 4 5 "<<(endl; I CAN"T DO THIS ON FORUMS CAUSE IT JUST SKIPS LINE -->BASICALLY ENDL
}




return 0;


}

The for loop should have its own scope - you have the starting bracket before the for statement. In short, it should be something like:

PHP Code:

for (x=1; x>=2000000; x++)
{    cout << 12345 << endl;
} 


Try cleaning up the code a bit and see what happens.

I believe this is what your trying to do. I made 2 loops. Just pick one. Though the "for" loop will eventually end, the "while (true)" will continue on until you close the window. btw, i commented out the loops so just remove the "//" when you write it. And just a note, you should not put "void" in the parameters for "main", and try not to use any includes if you dont need them...iomanip for example. Also, you can scrap the "return 0;" and finally, when you using a "for" loop it makes for cleaner code to make and initialize the variable in the parameters of the loop.

Edit: one more thing (sorry if im a little to much, just want to try to help with your code.) you dont need the "{" blocks in a loop unless its more then one line (though its fine if you do have them), and scrap the ";" at the end of the "for" loop. Finally, you have one the blocks in the wrong place. You would need one to open main and one to close, if you used it on the "for" loop you would need one right after the ")" on the "for" and one at the end of the loop.

errrr...........

I think u got the condition wrong in the "for loop" with
x>=20000000 <------loop stops at printing one line because condition is met!

should be
x<=20000000 instead. <-----will print 20000000 lines before ending.

however, it would look better if the program runs infintely until a input is read, much like FLG's infinte while loop, one post above this post.
