Answer 1

We can insert the string in a stack and when we extract the words, they will be in reverse order.

void ReverseWords(char Arr[])
{
    std::stack s;
    char *str;
    int length = strlen(Arr);
    str = new char[length+1];
    std::string ReversedArr;
    str = strtok(Arr," ");
    while(str!= NULL)
    {
        s.push(str);
        str = strtok(NULL," ");
    }
    while(!s.empty())
    {
        ReversedArr = s.top();
        cout << " " << ReversedArr;
        s.pop();
    }
}
