input output

why a blank line have such a output?
"is incorrect."

not " is incorrect."
(<space>is incorrect.)

Thanks a lot .
A blank line is truly a critical input !!!!

I modify my code

it is WA because of the sequence of figure




#include<iostream>

using namespace std;
int main(){
double rec[10][5];
double cir[10][4];
double tri[10][7];
bool fi[11];
double x,y;
char r;
int count, count2,fig,count3;;
bool in;
count=0;
count2=0;
count3=0;
int c2 ...

I use a different way

it is a kind of "Linear Programming Models"

and i have tried the data which is correct

but i still get WA

>_<



#include<iostream>

using namespace std;
int main(){
double rec[10][5];
double cir[10][4];
double tri[10][7];
double x,y;
char r;
int count, count2,fig ...

part of my code
I finally got AC :lol:

istringstream iss;

istringstream works !!!!
thanks a lot


#include<iostream>
#include<sstream>
#include<string>

using namespace std;
int pol(int,string);

void polf(string,string);

int main(){
int j,sum;
string po,k;

while(1){


if (!getline ...

Can you guys tall me why it is PE???


#include <iostream>
#include <string>
using namespace std;
int main(void){
int i,u,j;
string a;
while(getline(cin,a)){
if(a==""){continue;}
i=0;
//cout<<a.length()<<endl;
while(i<a.length()){

// cout<<a.length()<<endl;1
for(u=i;a[u]!=' ' && u<=a ...

Can U explain what lead to this result???

why did it gave me WA it is alright while num<100?
it seems logically right ,did it?



#include <iostream>
#include <cmath>
using namespace std;
int check(int);

int main(void){
unsigned long long int k,a,pa;
while(cin>>k){
pa=0;
a=2000000100;
if(k==0){break;
}
cout<<"The "<<k;
switch(k%10 ...

Excuese me but this time it turns out to be TLE. :-? :-?




#include <iostream>
#include <string>
#include <sstream>
using namespace std;
int t2w(string);
int main(void){
string a,b,d,e;
//char *c,d[11];

int sum;





while(1){
if (!getline(cin,b,'\n')) break;
if (!getline(cin,a,'\n')) break ...

It seems alright but I got WA.


#include <iostream>
#include <cmath>
//#include <ctype>
#include <iomanip>
using namespace std;
int gcd(int,int);
int main(void){
int a[50];
int k,u,j,t,m;
while(cin>>k){
if(k==0){
break;
}
m=0;
t=0;
for(u=0;u<k;cin>>a[u],u++);
// for(u=0;u<k;cout<<a[u ...

Here is my code.
This time is WA.

using namespace std;
int t2w(string);
int main(void){
string a,b,d,e;
//char *c,d[11];

int sum;





while(1){
if (!getline(cin,b)) break ...

the input which has two space.
it means a 0.

Thanks a lot.
May I ask u one more question???
in the following code
I can't correctlly get the input like "2 4 2 1 2"
how can i solve it??


.....

istringstream isss(a);
sum=0;
while(isss>>e){
sum=0;
istringstream iss(b);
while(iss>>d){
sum=sum*t2w(e)+t2w(d);
}
cout<<sum ...

but how can I get the input
i can't use "cin" it has " " space in the input?
my program is stuck so it is TLE.
isn't "getline" is used to "get a line"??
