Thread: Generate Possible combination of 6-bit Binary number

Can you post your code? It will be easier to comment on that, rather than try to give hints while not giving too much away.

In short we have to print Truth Table of 6 bit binary digits as truth table covers all possible combinations.

Exactly, so you will need no variables except the index variable in your for loop!

What are index variables?

The outer for loop should go from 0 to 64 so:

for(i = 0; i < 64; i++)

The inner loop would print 'i' as binary. If you do not know how to do that, then create a separate program to experiment with that. In this case it does not matter if it's printed from left or right since you are not interested in the actual values.

I'm assuming that interpretation myself. In that case you need 6 index variables and each goes from 0 to 1.

I did, but it does not mention that it has to be 6 nested loops. It could also be solved with 2 nested loops.

it is mandatory to use nested for() loop. I am not allowed to use any decimal to binary conversion.

The output Should be like this:

Code:

#include<stdio.h>
int main(void)
{
    int a,b,c,d,e,f,i;
    for(i=1; i<=64; i++)
    {
        for(a=0; a<=0; ++a)
        {
            printf("%d",a);


        }
        printf("\n");


    }
    return 0;
}

This program is for first column & i know it is incorrect

ok got it

The question is whether it can be solved "any way," for whether there is a specific implementation that is expected. oogabooga and I are assuming the latter (which would require six nested loops).

@OP: There are actually a lot of hints in these posts that might give you a more clear idea of what we're talking about.
