c++ - crt detected that the application wrote to memory after end of heap buffer

char* SequenceTokenAnalizer::NextToken(char delim)

    char* helpSequence;
    helpSequence = st1.NextToken();
    cout << helpSequence << endl;
    delete[]  helpSequence;
}

int i = currentindex, i2 = currentindex, cnt = 0, j = 0;

char *token=NULL;

if (Sequence[i2] == delim)
{
    while (Sequence[i2] == delim&& Sequence[i2] != '\0')
    {
        i2++;

    }
    while (Sequence[i2] != delim&& Sequence[i2]!='\0')

    }

        while (Sequence[i] == delim)
        {
            i++;


        }
        while (Sequence[i] != delim&& Sequence[i2] != '\0')

        token[j] = '\0';
        currentindex = i;

        return token;

        token = new char[cnt];


        if (Sequence[i] == delim)

                i++;
                j++;
            }
            token[j] = '\0';
            currentindex = i;
            return token;
        }

        else
        {
            while (Sequence[i] != delim)
            {

                i++;

            currentindex = i;

            return token;
        }
    }

class:

#include

using namespace std;

const int SIZE = 80;

class SequenceTokenAnalizer {

char Sequence[SIZE];
char delimiter;
int currentindex;

public:

SequenceTokenAnalizer(char str[]);

SequenceTokenAnalizer(char str[], char delim);

int LengthSequence();


int CountAllTokens();
void ResetTokens();
int CountTokens();
bool HasMoreTokens();
bool HasMoreTokens(char delim);
char* NextToken();
char* NextToken(char delim);
bool Equals(SequenceTokenAnalizer other);
bool NotEquals(SequenceTokenAnalizer other);
bool isCommonToken(SequenceTokenAnalizer other);

void PrintCommonTokens(SequenceTokenAnalizer other);

};

after using delete[] in main I get crt detected that the application wrote to memory after end of heap buffer please helppppp here i have sequences and have to return next tokken from current index
