    getting an error I can't figure out....

    I was wondering if someone could help I am getting these error message and I can't figure out how to fix them any ideas??

    error C2228: left of '.string' must have class/struct/union type
    C:\Documents and Settings\Owner\My Documents\Computer error C2664: 'lin_search' : cannot convert parameter 1 from 'class index [2000]' to 'class index *[]'
    Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast

    here is my code
    class index{
    		int number;
    		char string[100];
    		char url[50];
    bool lin_search(index *l[], char word[]){
    	for(int i = 0; i <= 20; i++) 
    		if(l[i].string == word)
    			return true;
    	return false;
    I call the function like this:

    	index w[2000];
    	char word[100];
    	int count = 0;
    	ifstream filein("collection.txt", ios::nocreate);
    					addrin >> word;
    					if(lin_search(w, word) == true){}
    I hope someone can help. Thanks

    >>bool lin_search(index *l[], char word[]){

    Should be:

    bool lin_search(index l[], char word[]){
    #include <cmath>
    #include <complex>
    bool euler_flip(bool value)
        return std::pow
            std::complex<float>(0, 1) 
            * std::complex<float>(std::atan(1.0)
            *(1 << (value + 2)))
        ).real() < 0;

    I gave that a try but it wasn't passing the class object through the function I couldn't check if the strings were the same.

    I believe your problem is that l[i] is a pointer, so you need to write your if statement like so:
             if(l[i]->string == word)
                 return true;
    At least thats what the error is complaining about.
