i want to store binary equivalent of decimal number in char array by applying below code, but the problem is i'm not able to hold the last bit of the decimal number. I am getting garbage values

   int k,j;
  char c[40];
  j=32;
while(k)
    {    
     k=k>>1;
     c[j]=k|1;
     j--;
     }

     puts("number is");
     puts(c);

Whad do you exactly want? Store each bit in own character, or store each byte in own character (which exactly the size of byte)?

what i want to convert a decimal to its binary equivalent and store in a char array
the size of byte should be 4(int) bytes

What you want to see if you output your char arry? String of 0s and 1s or 4 characters (possibly invisible) with values corresponding to individual byte of integer?

Yes. Integer 0 and chracter '0' are different. integer 0 is used to denote end of string.
