solved  for loop

Hakate (29)   Link to this post
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:

1
2
 
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:
1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
 
#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?

I don't think I could get that output if I tried.
Grey Wolf (1599)   Link to this post
If, as you have previously said, you are outputting from an array, have you got guards to stop it going out of bounds?

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?

Again I'm not entirely sure what you want, possibly:
1
2
3
 
bool test = true;
//...
test = !test; // set test to its opposite value

could a ternary statement be what you're looking for?
1
2
 
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.
