Checking array for string

This is a discussion on Checking array for string within the C Programming forums, part of the General Programming Boards category; I really appreciate all the suggestions, but I'm not any less confused now. The example program given uses char*, but ...

    I really appreciate all the suggestions, but I'm not any less confused now. The example program given uses char*, but before we were talking about using const char [][].

    Maybe it helps if I just give the whole code of my test program. It does compile now and It doesn't crash either. Unfortunatly however, it doesn't do what I want it to do. It just uses "result" as whatever value I gave it at the declaration.
    This is what I have now:
    The function:
    Code:
    int stringcheck(const char* string1_to_check_for,const char* string2_to_check_for,const char array_to_check[][8],int length_of_array){
    
    int i=0;
    int result=0;
    
    for(i = 0; i < length_of_array; i++)
    {
        if (strcmp(string1_to_check_for, array_to_check[i]) == 0 ||
            strcmp(string2_to_check_for, array_to_check[i]) == 0)
        {
            return result = 1;
            break;
        }
    }   
    
    return result = 0;
    }
    And in the main for testing this function:
    Code:
    const char comb_array[][8] = 
    {    "13",
         "26",
         "158",
         "86",
         "88",
         "1212",
         "142",
         "89",
         "14",
         "410",
         "1116",
         "168",
         "12",
         "34"
    };    
        
        
    
    
    int result=5;
    int startype1 = 1;
    int startype2 = 4;
    int comb_array_pointer = 14;
    char current_comb1[8];
    char current_comb2[8];
    
        
    sprintf(current_comb1, "%d%d",startype1,startype2);
    sprintf(current_comb2, "%d%d",startype2,startype1);
    
    printf("checking for the strings: '%s' '%s' \n", current_comb1, current_comb2);
    
    stringcheck(current_comb1,current_comb2,comb_array,comb_array_pointer);   
    
    printf("String found true/false (1/0): %d\n",result);
    Maybe you can help me, using what I have so far?

    shoouldn't you assign to result something to see the changes in this variable?
    currently you just ignore the return value of your checking function
    The first 90% of a project takes 90% of the time,
    the last 10% takes the other 90% of the time.

    Why does it ignore the return value? First i define "result" as whatever and then I run the function and I thought it would use the new changed version of "result".

    Oh wait! I must use result = stringcheck(arguments);
    But in that case, why would i want to return "result" from my function, if i can't even use this variable??

    OK, let's see now, in my example, a[][] is a 2D char array
    your array_to_check[][] is also a 2D char array.

    I needed the "address of" operator highlighted in red, below, in my example program.

    You need it, but still have not added it.

    Wake up!


    Code:
    if((strcmp(string, &a[i])) == 0)
    
    if (strcmp(string1_to_check_for, array_to_check[i]) == 0 ||
            strcmp(string2_to_check_for, array_to_check[i]) == 0)

    array_to_check[i] is char*

    why to modify it to char**? ctrcmp does not know what todo with it

    I'm with vart on this one.

    @Ayreon:
    The result inside your "is this a match" is a different variable "result" from the one inside your main function - they just HAPPEN to have the same name, but if you call one of them fred, it will not change anything. Return means "give this back as a value from this function" - think of it as a mathematical function, e.g. sin() or sqrt() - you do use them with a "x = sqrt(y);", right? You do not know what variable names are used inside sqrt() - nor should you. The same applies to your own functions - the names of variables inside one function has nothing to do with names of variables in another function.

    It is something called "scope". The area where a particular variable is available is "its scope", and it is always the pair of braces that enclose the variable that define it's scope.

    Code:
    int stringcheck(const char* string1_to_check_for,const char* string2_to_check_for,const char array_to_check[][8],int length_of_array){
    
    int i=0;
    int result=0;
    
    for(i = 0; i < length_of_array; i++)
    {
        if (strcmp(string1_to_check_for, array_to_check[i]) == 0 ||
            strcmp(string2_to_check_for, array_to_check[i]) == 0)
        {
            return result = 1;
            break;
        }
    }   
    
    return result = 0;
    }
    Result, in this function is completely meaningless. You only assign it within the return statement - you should EITHER use two return statements, eg. "return 1", or use a "result = 1" and then a single "return result" at the end of the function (where you initialize result = 0; and set it to one in the loop.

    If you go with the two return statements, you will not need the break statement, as return means "leave this function now". Of course, if you have a single return, then using a break will reduce the amount of loop iterations.

    There are two "styles" when it comes to return statements - one says have only one return statement (at the end of the function), the other is "return wherever and whenever the result is known and the function is 'done'". You should CHOOSE which one you follow (it is obviously still ALLOWED to one single return in the latter style). There are good arguments for both, and I'm not going to explain much about it here - start a new thread if you really want to have a discussion on that subject.

    The function works now, without the & though.
    Thanks for the explenation on the function about return, I totally get that now.

    When I implement this function in my bigger program though, I get a whole lot of incompatible pointer types, thingies without a cast, assignments to read-only locations and that sort of stuff.
    (Well it starts with one of these but when I try to fix stuff, I only get one of these errors instead.)

    I'll just start another topic on that, it hasn't got much to do with the checking function anymore.

    Of course, you mean strcmp().

    I'm not sure myself, but when I removed the '&' to check it, my example program would no longer run, although it compiled just fine.

    One more question I think, could still be suitable for this topic:

    What if my array_to_check changes everytime before I run my function. It doesn't change during the running of the function but in the larger program it is not defined as a const char because it is not constant.
    Still I had to make it const in my function argument, so now I get incompatible argument types.
    And if I do define this array to be a constant in the main program, the argument types are fine, but I get an "assignment to read-only location" error.

    What should I do?

    You have to work around that. For whatever reason, a const parameter does not accept incoming mutable arguments, which doesn't really make sense, but...

    You can avoid a cast with something like
    Code:
    void foo(const char quz[][8]);
    
    int main()
    {
        char test[8][8];
        const char (*arg)[8];
    
        arg = test;
        foo(arg);
        return 0;
    }
    Of course, all of these are bad variable names, but the example is sound.

    You don't need to do that since a local pointer is made, which is const, and assigned the address from the array you pass. That's why your original array can be non-const while the one the function accepts can be const. This is basics basically.
    However, why it does not work for you, I can only guess. The best, and easiest, way to figure it out is to show the code, I guess.

    Better yet, learn how to use debuggers.
    And learn not to hijack threads.
