for loop

[Hakate]

Hello

i need to make a for loop that changes direction everytime a specific number is randomized, im not really familiar with that.

example: if number 4 is randomized the loop changes from ++ to -- also the values changes and if another 4 is the value the loop changes from -- to ++

any help appreciated

I of course don't understand your objective. Without it I can't make an accurate method of accomplishing what your wanting.

However, I'm great at guessing. I'm assuming that you want something to lower or heighten the value of a variable depending if it's lower or higher than a constant value. This can be accomplished using if / else statements:

if (myNumber > 10) std::cout << "myNumber is greater than 10!" << std::endl;
else if (myNumber >=0) std::cout << "myNumber is less than 10! NOOOOO" << std::endl;

No not really, i loop out something in a array in a order i type in like 0 to 5 but if i type in the number 4 i want it to loop from 4 to 0 aka backwards lets say i loop out 0 to 5

0 1 2 3 4 5

and when i type in 4 it shuld be like this

4 3 2 1 0

also i want it to do that in the same loop as the other

Like computerquip, I don't fully understand what you are trying to do

perhaps somthing along the lines of:

#include <iostream>

using namespace std;

int main()
{
    int step = 1;

    for (int i = 1; i > 0; i += step)
    {
        cout << i << endl;

        if(i == 5) step = -1;
    }
    return 0;
}

Edit:
from the above post, It looks like you want two loops the first to display, then get some input, then another to display the reverse.

ok the thing is i think i got an error in my code somewhere since when i try to step backwards the output becomes like this

Maybe you should post the code that you are having a problem with?

[S6k9GNh0]

I don't think I could get that output if I tried.

[z05DSL3A]

If, as you have previously said, you are outputting from an array, have you got guards to stop it going out of bounds?

[Hakate]

That was the problem actually i forgot it starts on 0 :/

is it possible to change a boolean from true to false and false to true in 1 if statement btw?

[z05DSL3A]

is it possible to change a boolean from true to false and false to true in 1 if statement btw?

Again I'm not entirely sure what you want, possibly:

bool test = true;
//...
test = !test; // set test to its opposite value 

[Mal Reynolds]

could a ternary statement be what you're looking for?

bool bVar = false;
bVar = ( /* some boolean expression */ ? true : false );

This is ridiculous. If we can't figure out what he wants, there's no point in wasting our wisdom on guessing.

sorry just noticed. :0)

#include <winuser.h>

// ...

BOOL  bDirection = TRUE;
int	  i = 0;

for(; /* set condition here*/; (bDirection ? i++ : i--))
{
  // do stuff
  
  if(IsFour())
    bDirection = TRUE;
  if(IsTen())
    bDirection = FALSE;
}

// if bDirection == TRUE, then i++
// if bDirection == FALSE, then i-- 

?

looks good to me..
