Loop counter

[Parul Bagadia]

I have written a function for converting a decimal no. in binary no.
Here what happens is in convert function my j turns out to be 1244860..which i got to know by debugger. Before going in for loop;its value is 0, in for loop value of i-1 is 3...but value of j randomly becomes 1224860.
Hows that happening?
I did the program in Microsoft Visual Studio C++ 6.0

#include<stdio.h>
conv(int d1,int d2)
{
int rem=0,qut=1,i=0,j=0;
int store[20]={0};
while(qut!=0)
{
rem=d1%2;
qut=d1/2;
d1=qut;
store[i]=rem;
i++;
}
for(j=i-1;j>0,i>0;j--,i--)
{
printf("\n%d",store[i]);
}
}
void main()
{
int no1=0,no2=0;
printf("\nEnter first decimal no.\n");
scanf("\n%d",&no1);
printf("\nEnter second decimal no.\n");
scanf("\n%d",&no2);
conv(no1,no2);
}

Why not just:

for(j = 0; j < i; ++j)
{
     printf("\n%d",store[j]);
}
 

?

BTW: I assume this printf is a debug display. If it is, stop doing that because you have to change the code to take the display out and then you are no longer sure the code still works. Use your debugger only.

If it is not a debug display, then take the display out and return a string with the binary values.
