What's wrong with my code?!! I checked every sample output from this post & my code generate correct ans. but got WA in uva. plz help me.
#include<stdio.h>
#include<math.h>
int main()
{
long int n,n1,rs;
int i,j,r;
bool chk,chk2;
while(scanf("%ld",&n)!=EOF)
{
chk=true;
if(n==0 || n==1)
chk ...

why I got WA? I was check every input set (including from here). but still WA?!! :x :x :x Help me frndz

#include<stdio.h>
#include<stdlib.h>
int main()
{
int n,i;
int dt1,mn1,yr1,dt2,mn2,yr2;
char a1,b1,a2,b2;
scanf("%d",&n);
for(i=1;i<=n;i++)
{
scanf("%d%c%d%c%d",&dt1,&a1,&mn1,&b1,&yr1 ...

Why i got WA?
#include<stdio.h>
#include<stdlib.h>

int main()
{
int a,rs=0,r,i,fs,b,n,count;

scanf("%d",&n);

for(i=1;i<=n;i++)
{
scanf("%d",&a);

rs=0;
count=0;

while(a!=0)
{
b=a;
rs=0;

while(a!=0)
{
r=a%10;
rs=rs*10+r;
a=a/10;
}

fs=b+rs;
a=fs;

if( b == rs )
break ...

Why I got compilation error?!!!
#include<stdio.h>
#include<stdlib.h>
#include<string.h>
int main()
{
char a[1000];
while(scanf("%s",&a)==1)
{
if(a[0]=='\n' || a[1]=='\n')
printf("\n");
else
printf("%s ",strrev(a));
}
return 0;
}

//why I got WA for this code?!!! plz help me.

while(gets(a))
{
count=0;
p=strtok(a," !.");
while(p!=NULL)
{
p=strtok(NULL," !.");
count++;
}
printf("%d\n",count);
}
return 0;
