You forgot to assign a value to $conn from the return value of DBConnect(), eg this DBconnect($config); should be $conn = DBConnect($config); You also don’t need to use global $conn in your script as it will be in scope. I’d also recommend not catching the exception from the PDO constructor. How else will you know … Read more
The problem is that in the DeckOfCards class, the deck vector is never added to, so it’s empty. In the constructor, assign newDeck to deck: deck = newDeck; There is also another problem in the constructor: You declare newDeck to contain 52 entries, but then you use push_back to add new entries to the vector. … Read more

You have two lines there. What you want to do is to pick the closer line for each pixel, and calculate the distance to it. This will be your intensity at a given point. Furthermore do a fade to black as you approach the bottom of the image (use your pixel’s y position to do … Read more
It turns out there is a general solution, which does not depend on word size, or even on two’s complement arithmetic. Here it is: int is_zero(int x) { unsigned y = x; unsigned c0 = y^y; unsigned c1 = ~(~c0 + ~c0); unsigned c1h = ~c0 ^ (~c0 >> c1); unsigned y2 = y + … Read more
The design of your table is going to depend a lot on the requirements you need fulfilled. In the situation where a member can only ever be assigned to a single room, but rooms can have many members, then the answer that Double H gave is exactly what you’re looking for: CREATE TABLE members ( … Read more
These: scanf(“%i”, y[i][j]); scanf(“%i”, d[i]); needs to be: scanf(“%i”, &y[i][j]); scanf(“%i”, &d[i]); as %i in the scanf expects an int*(address of the variable), not an int(value of the variable). Another problem is that you do division by zero here: inv[i][j] = co[i][j] / D; when D is zero. solved C programming code error

Thanks for improving your question. One approach you could take is to add a class to each professor option which indicates which majorID it’s associated with like this: <div class=”form-div”> <h3><label for=”prof”> Then Select Professor: </label> <br></h3> <select class=”form-input” id=”prof” name=”prof”> <?php foreach ($professors as $prof) { ?> <option class=”major-<?php echo $prof[‘majorID’]; ?>” value=”<?php echo … Read more
