What's wrong in this code?

Question

#include<stdio.h>
void main()
{
int a,b,sum,difference;
int *c,*d;
scanf("%d %d",&a,&b);
printf("%d\n%d\n",a,b);
if(difference>0)
{
sum = a+b;
difference = a-b;
c = &sum;
d = &difference;
printf("%d\n%d",*c,*d);
}
else
{
sum = a+b;
difference = (-1)*(a-b);
c = &sum;
d = &difference;
printf("%d\n%d",*c,*d);
}
return 0;

}
When i run it on C coding in android its working but when i run in on sololearn its gives negative value on difference whereas i want the absolute value of the difference.
Please help.

#include<stdio.h>
void main()
{
int a,b,sum,difference;
int *c,*d;
scanf("%d %d",&a,&b);
printf("%d\n%d\n",a,b);
difference=a-b;
if(difference>0)
{
sum = a+b;
difference = a-b;
c = &sum;
d = &difference;
printf("%d\n%d",*c,*d);
}
else
{
sum = a+b;
difference = (-1)*(a-b);
c = &sum;
d = &difference;
printf("%d\n%d",*c,*d);
}
return 0;
}
//this should work

Maybe you just forgot to copy this short:
difference=a-b;
line???

Answer 3

I liled to help

Answer 4

ypu are using difference uninitialised... write :
difference=a-b before the if-clause

Answer 5

I did that too in C coding app but there it makes the code show the negative value and not the absolute.

Answer 6

Sorry i didn't see your code i was typing.

Answer 7

No i didn't write that.
