excuse me ,can anyone tell me why I got a WA?
because I can't find where I do wrong .
thanks in advance :)
and sorry for my poor English..




#include<stdio.h>
#include<math.h>
#include<string.h>
int main()
{

char word[21];
double sum=0;
int i,y,factor;




while(gets(word) != NULL ...

helloneo
thank you very much. :D
but this time I got WA ...
can anyone tell me why?
thanks!

this is my code:


#include <stdio.h>
#include <string.h>
int main()
{
int i;
int k;
int count;
char sl[2000];

while( gets(sl) != NULL )
{
k = strlen(sl);
count = 0;
for(i=0;i<k;i++)
{

if ...

excuse me , can't anyone tell me,why i got an OLE ?
and I don't know why I can't end this program when I enter"ctrl + z"
ah .. sorry for my poor English

this is my code:


#include <stdio.h>
#include <string.h>
int main()
{
int i;
int k;
int count;
char sl[2000];

while( gets(sl ...

this time I include math.h header file...
but I got an WA?
Can anyone tell me why?
and..gcc &g++ is what?
thx!! :D

this is my code:

#include <stdio.h>
#include <math.h>
#include <stdlib.h>
int main()
{
double a ,b ,c ,r ,s ,s2 ,area;

while (scanf("%lf %lf %lf",&a,&b,&c) != EOF)
{

s = ( a ...

int main()
{
double a ,b ,c ,r ,s ,s2 ,area;

while (scanf("%lf %lf %lf",&a,&b,&c) != EOF)
{

s = ( a + b + c ) / 2.0;
area = sqrt(s * (s-a) * (s-b) * (s-c));
s2 = a + b + c;
r = 2.0 * area * (1.0 / s2);
printf("The radius of the round table is: %.3lf\n",r);



}

return 0;
}

i ...

int main()
{
double a ,b;
double factorial(double);
double result;
double n;

while (scanf("%lf",&n) == 1)
{
if (n > 10000.)
break;
else
{
result = factorial(n);

if( fmod(result,10.) != 0.)
{
a = fmod(result,10.);
printf("%5lf -> %lf\n",n,a);
}
else
{
do
{
b = result / 10 ...

int main()
{
long long int num1 ,num2,answer;


while(scanf("%lld %lld",&num1,&num2) != EOF)
{
if(num1 > num2)
{
answer = num1 - num2;
printf("%lld\n",answer);
}
else
{
answer = num2 - num1;
printf("%lld\n",answer);
}

}


return 0;
}

I wrote this in C!
why I still got a WA ...
