    I think you are talking about the number system conversion programs...If you want to convert a decimal number into binary number system then here is the code..
    Code:
    #include<stdio.h>
    #include<conio.h>
    #include<math.h>
    
    void dec_bin(long int num)   // Function Definition
    {
    long int rem[50],i=0,length=0;
    while(num&gt;0)
     {
     rem[i]=num%2;
     num=num/2;
     i++;
     length++;
     }
    printf("\nBinary number : ");
         for(i=length-1;i&gt;=0;i--)
                 printf("%ld",rem[i]);
    }
    //================================================
    void main()
    {
    long int num;
    clrscr();
     
     printf("Enter the decimal number : ");
     scanf("%ld",&amp;num);
    
        dec_bin(num);   // Calling function
    
     getch();
    }
