[question] C++ multi application.

[GoshSpeed]

Hey,

i building on a project called multiapplication .

Question: if x = 2 , and i need the next number : so 2*2 = 4 , 2*4= 8 , 2*8 = 16 etc.
but its a long way to type on my keyboard, is there a faster way to program this?
this is the code that i have done now.

Code: Select all

#include <iostream>
using namespace std;
int main(void)
#define x 2

{
      cout<< "\n" << x*2;
      cout<<"\n" << x*4;
      cout<<"\n" << x*8;
      cout<<"\n" << x*16;
      cout<<"\n" << x*32;
      cout<<"\n" << x*64;
      cout<<"\n" << x*128;
      cout<<"\n" << x*256;
      cout<<"\n" << x*512;
       cout<<"\n" << x*1024;
       cout<<"\n" << x*2048;
      cout<<"\n" << x*4096;
      cout<<"\n" << x*8192;
      cout<<"\n" << x*16384;
      cout<<"\n" <<x*32768;
      cout<<"\n" <<x*65536;
      cout<<"\n" <<x*131072;
     
      cout <<"\n";
       system ("pause");
       }

Sorry , if my question isn't clear ,i got at the moment not a better explanation .
And sorry for my language, English is not my native language.

Thanx,

Im not sure if this is what you wanted but heres what I did.

Code: Select all

#include <iostream>
#include <math.h>
using namespace std;
int main()
{
   for(int counter = 1; counter <= 17; ++counter)
   {
      cout << pow(2.0, counter) << endl;
   }
}

multiapplication sounds like a pretty damn good program, but the question...

[mischief]

Code: Select all

#include <iostream>
#include <math.h>

int main() {
   for(int counter = 1; counter <= 17; counter <<= 1) {
      std::cout << counter << endl;<br>
   }
}

bitshifting is a faster operation than calling pow ._.
works great for powers of 2 ^^

GoshSpeed, I recommend you learn about looping in C++ or loops in general.
