how do I convert a string to char array to find a substring within a string?

[red222]

I am trying to find a string within a substring using strstr. This only works with char arrays. I have an array of objects of which I am searching a particular property which is a string.

char *strPtr;
 
    int index = 0;
    bool located = false;
 
    do
    {
        for(index = 0; index <NUM_BOOKS; index ++)
        {
            strPtr = strstr(bookList[index].getTitle(), book);//str1, str2);
            if(strPtr == NULL)
            {
                cout << "No matching titles were found.\n";
            }
            else
            {
                located = true;
                found.push_back(index);
            }
        }
 
    }while(index < NUM_BOOKS && !located);
 

I am using C++

If you declare string s you can then use getline(cin,s) to load a string to s from the keyboard.
You can print the string with cout<<s;
string s1;//declare s1.
You can get a substring from s with for example s1=s.substr(5,14) s1 gets the 6th element in the array s[] plus the next 13 characters including spaces.
cout<<s1;//prints s1 which is 14 characters long starting with the 6th element in array s.

This is C++ and not C so don't use strstr.

What you want is the find_first_of algorithm. You pass in your collection of objects plus a function pointer to a function that returns a bool if your search criteria are met or not.

Do you have any examples you could show me? I'm not exactly sure what you are saying.
