The task is follow:
Implement function char* int2bin(int x) which would return a string representation of int x in binary form. I.e.: 00001001 10001110 11011011 10011011
How Can I make my code output that ? So far I have decimal number returned as binary but not as the display way of what the task wants.

#include <stdio.h>
#include <math.h>

int n=5;
void getbits(unsigned int x)
{
for(int i=(sizeof(int)*n)-1; i>=0; i--)
(x&(1<<i))?putchar('1'):putchar('0');

printf("\n");
}

int main()
{
int j = 3567;
printf("Decimal: %d Binary: ", j);
getbits(j);
return 0;
}

Thank you

I do not understand what this magic definition

 
 int n=5; 
 

means in your code.

As for the question then you need to allocate dynamically a character array and write character representations of bits into the array instead of the standard output stream as you do in your code.
