I can't find my mistake, if someone know suggest me my mistake please:
#include <iostream>
#include <string>
#include <string.h>
using namespace std;

char* reverse(char* str)
{
    char* temp = new char[strlen(str) + 1];
    int i, n = strlen(str);
    if(str[n-1] == ',' || str[n-1] == '-' || str[n-1] == '.' || str[n-1] == '?' || str[n-1] == ':' || str[n-1] == ';')
    {
        temp[n-1] = str[n-1];
        n-=1;
    }

    for(i = 0; i<n; i++)
    {
        temp[i] = str[n - i - 1];
    }
    if(n == strlen(str) - 1)
        temp[i+1] = '\0';
    else temp[i] = '\0';
    return temp;
}


int main()
{
    string *as = new string[1000];
    int i = 0;

    #ifndef ONLINE_JUDGE
        freopen("input.txt", "rt", stdin);
        freopen("output.txt", "wt", stdout);
    #endif

    while(getline(cin,as[i++]))
    {

    }

    for(int j = 0; j<i-1; j++)
    {
        const char* str = as[j].c_str();
        char* ch = new char[strlen(str) + 1];
        strcpy(ch,str);
        //ch[strlen(str)] = '\0';
        //cout<<ch;
        char* temp = strtok(ch," ");
        cout<<reverse(temp);
        while(temp != NULL)
        {
            temp = strtok(NULL," ");
            if(temp != NULL)
                cout<<" "<<reverse(temp);
        }
        cout<<endl;
    }

    return 0;
}
