I got RE why? thanks everyone! :wink:


#include <stdio.h>
#include <stdlib.h>

int compare (const void * a, const void * b);

int compare (const void * a, const void * b) //compara inteiros
{
return ( *(int*)a - *(int*)b );
}

int main ()
{
int i,j,k,temp;
int quantidade = 0;
int vetor[55 ...

why WA?

#include<stdio.h>

int main()
{

double a,b,c;

while(scanf("%lf %lf" ,&a ,&b)==2)
{

if(a>b)
{
c = a - b;
printf("%0.lf\n",c);
}
if(a<b)
{
c = (b - a);
printf("%0.lf\n",c);
}

}
return 0;
}


it returns 4294967296 on 4294967296 0 and vice-versa.. :roll:
thanks!
