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(5,1 4) 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.
