Outputting Array
Hi,
I really new on C++, and I try to output an array (All possible output)
for example:
we have an array with 3 element, all possible answer would be 3! = 3 * 2 * 1 = 6
//
#include <iostream>
using namespace std;
int main()
{
int arr[3] = { 1, 2, 3 };
for (int i=0; i<3; i++)
{
for (int j=0; j<3; j++)
{
if (i != j)
{
for (int k=0; k<3; k++)
{
if ((k != i) && (k != j))
{
cout << arr[i] << "\t" << arr[j] << "\t" << arr[k] << "\n";
}
}
}
}
} // END For
return 0;
}
//
On example above I use 3 FOR loop and 2 IF. My question is if we have an array with 200 element, we will have 200 FOR loop and 199 IF.
Is there a better way to use (less using FOR and IF)? if yes how?
(As everyone in this forum know being C++ programmer means we have to solve problems by ourselves, but it's been 1 month I try to figure this out but I cannot, and I hope you guys can help me for that)
Thanks
Regards
