if(stra[x]==0x00){
aout=true;
}
if(strb[x]==0x00){
bout=true;
}

This is wrong.

A correct way to implement this check:
aout=!(x<stra.size());
bout=!(x<strb.size());



I change my code as those codes above and got AC. But I compiled the old codes and new coeds for comparison and there ...

i got WA but i think my last line should be right. can anyone tell me what's wrong with my code? thanks.

I got WA on 639, and I have tried a lot of cases. Can anyone help me with my problem or provide me inputs?


#include<iostream>

using namespace std;

const int mmax=5;

thanks....I fixed the code and submitted it again, and I got AC!

(No array)


#include<iostream>

using namespace std;

bool isv(char);

int head;

int main(){
char w,wal;

while(cin.get(w)){
if((w>=0x41 && w<=0x5A) || (w>=0x61 && w<=0x7A)){
if(head==0){
if(isv(w)){
head=1;
cout<<w ...

why I got WA? I had tried all the cases....
