Javac wa

[anitraj]

Hi all,
I am trying out with this Java vs C++ for a long time and i am getting WA. I have already checked out all related topics in forum and my program seems to give correct output. Can anyone Please help me with this?

#include<iostream>
using namespace std;
bool error;
bool c,java;
void checkc(char *a)
{
	int i,n=strlen(a);
	if(a[0]=='_' || a[n-1]=='_')
	{
		error=true;
		return;
	}	
	for(i=0;i<n;i++)
	{
		if(isupper(a[i])!=0)
		{		
			c=false;
			return;
		}	
		if(a[i]=='_' && a[i+1]=='_')
		{	
			error=true;
			return;
		}
	}
	c=true;
}
char* convertc(char *a)
{
	char *b=new char[110];
	char c;
	int i=0,j=0,n=strlen(a);
	bool d=false;
	for(i=0;i<n;i++)
	{
		c=a[i];
		if(c=='_')
		{			
			d=true;
			continue;
		}	
		if(d==true)
		{		
			b[j++]=toupper(c);	
			d=false;
			continue;
		}	
		b[j++]=c;
	}	b[j]='\0';	
	return b;
}
void checkjava(char *a)
{
	int i,n=strlen(a);
	int count=0;	
	bool b=false;	
	for(i=0;i<n;i++)	
		if(isupper(a[i])!=0)
			count++;
		else	
			if(a[i]=='_')
			{
				error=true;		
				return;
			}
			if(count==n)
			{		
				error=true;
				return;
			}
			java=true;
}
bool tmperror(char* a)
{
	int i,err=0;
	if(!isupper(a[0]))
     return false;
	for(i=1;i<strlen(a);i++)
		if(isupper(a[i]))
			return false;
	return true;
}
char* convertjava(char *a)
{
	int i,n=strlen(a),j=0;
	char *b=new char[110];
	char c;
	for(i=0;i<n;i++)
	{
		c=a[i];		
		if(isupper(c)!=0 && i!=0)
		{		
			b[j++]='_';
			b[j++]=tolower(c);
			//i++;
			continue;
		}
		if(isupper(c)!=0 && i==0)
		{			
			b[j++]=tolower(c);	
			continue;
		}
		b[j++]=c;
	}
	b[j]='\0';
	return b;
}
int main()
{
	char *a=new char[110];	
	char *b=new char[110];	
	memset(a,' ',110);	
	while(cin.getline(a,110))
	{		
		error=c=java=false;
		if(tmperror(a))
		{
			cout<<"Error!"<<endl;
			continue;
		}
		checkc(a);
		if(c!=true && error!=true)
			checkjava(a);	
		if(c==true)
		{	
			b=convertc(a);
			cout<<b<<endl;
		}		
		else	
			if(java==true)
			{			
				b=convertjava(a);	
				cout<<b<<endl;
			}		
			else
				if(error==true)
				{
					cout<<"Error!"<<endl;			
					b=false;
					continue;
				}
			memset(a,' ',110);
	}
	exit(0);
	return 0;
}

Thanks in advance

Why 110 should be sufficient for this problem?

like;
aAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA..........( total length 100, not shown here)
the solution will be over 200 size.

Thanks Hasan
But even after changing the length of string i am getting WA

Hi,
I ve tried to implement all the test cases given in the forums , yet i get WA ..
I have attached my code, Please Help me spot my mistake.
Thanks a lot,
Vidya Sagar S

#include<iostream>
#include<string>
using namespace std;
int checkj(string a){
	int n=a.size();
	for(int i=0;i<n-1;++i) {
		if(!isalpha(a[i]) && a[i] !='_') return 0;
		if(a[i]=='_' && (isupper(a[i+1]) || a[i+1]=='_')) return 0;
		}
	return 1;
}
int main() {
	string a,re;
	int n,i;
	while(cin >> a) {
		n = a.size();
		re = "";
		if(isupper(a[0])||a[0]=='_'||a[a.size()-1]=='_') {cout<<"Error!\n";continue;}
		if(a.find('_')==string::npos) { // Camel Notation -> Mnemonic
			for(i=0;i<n-1;++i) {
				re+=a[i];
				if(islower(a[i]) && isupper(a[i+1])) {
					a[i+1] = tolower(a[i+1]);
					re+='_';
					}
				}
			re += a[i];
			}
		else { // To Camel
			if( !checkj(a)) {cout<<"Error!\n";continue;}
			for(i =0;i<n-1;++i) {
				if(a[i]=='_' && islower(a[i+1]) ) {a[i+1]=toupper(a[i+1]);continue;}
				re += a[i];
				}
			re +=a[i];	
			}		
		cout << re << endl;
		}
	}

Read the problem statement. You've missed a very important detail.

[mohit30]

i have tried almost everycase even then wa is there please help.

[leppyr64]

Here's the problem:
aA

[mohit30]

my answer is coming out to be a_a, is that wrong????

[leppyr64]

Print your result to a file and then view it in a text editor that shows unprintable characters such as Notepad++.

Tou actually output more than just a_a.

Hey,please help me ..I'm getting WA
here is my code.. give me a test case where my code goes wrong please
