[ad_1] Your SQL query/logic is completely wrong. What you should do is check if that user and password combination exits in database using WHERE clause. But actually you are doing is fetching each row and checking for equality. In such situation you can also get n numbers of wrong credentials. $query = mysql_query(“SELECT * FROM … Read more
[ad_1] A for loop is often written int i; for (i = 0; i < 6; i++) { … } Before the first semicolon, there is code that is run once, before the loop starts. By omitting this, you just have nothing happen before the loop starts. Between the semicolons, there is the condition that … Read more
[ad_1] In your outer while loop you need this: overtime = 0; if (hoursWorked>8) overtime = (hoursWorked-8)*(rateOfPay*1.5) – (hoursWorked-8)*rateOfPay; // Calculate OVERTIME HOURS sets the overtime to zero for each iteration, and you’ll have to subtract the normal rate for overtime hours (otherwise you add them twice) and then you’ll have to add the overtime … Read more
[ad_1] for this code you cannot use input as a variable so I would rewrite it as this: choice = input(“”) #This will get a string that the user types. if “stay” in choice: #This will execute the code below if the user has typed something with stay in it print dead(“You were struck by … Read more
[ad_1] By the time p3 equals 10, it will never re-enter the while (p3 < 10) loop (because once you’ve incremented it to 10, it will never be less than 10 and will never re-enter that loop). So yes, p and p2 do increment, but they never get printed because p3 == 10 at that … Read more
[ad_1] I apologize in advance, for I’m still actively learning C++, but think I can reproduce your desired output in PHP while loops. From what I could gather, the formula you would need is n = n – i with i being the iterator that doubles each day and n being the number of bags… … Read more
[ad_1] You never update the value of GuessedNumber inside the loop. Therefore, if the code enters the loop, it will never leave it because RandomNumber != GuessedNumber will always be true. You need to do something like this: import random RandomNumber=(random.randint(0,100)) GuessedNumber=int(input(“Guess any whole number between 0 and 100! “)) while RandomNumber != GuessedNumber: print(“Unlucky … Read more
[ad_1] I’ll keep it very simple, because this is very basic stuff. i = 10 Variable i is initialised as 10. while i > 0: print i*’*’ + 2*(10-i)*’ ‘ + i*’*’ i -= 1 While variable i is bigger than 0, it prints the string * i times, an empty space 2 * (10 … Read more
[ad_1] Inside foreach you are updating $result and $row with new values, so the outer while will stop to loop. Rename those variables and it’ll work! [ad_2] solved while loop inside foreach loop inside while loop [closed]
[ad_1] If it helps you to understand, you can rewrite it from AND to OR: while (command != “quit” && command != “q”) { // do job } is equivalent to while (!(command === “quit” || command === “q”)) { // do job } https://en.wikipedia.org/wiki/De_Morgan%27s_laws 5 [ad_2] solved OR and AND operator confusion in Javascript … Read more
[ad_1] if 2<x<10: X never be more than 2. Because at the beginning you give 0 to X. And you say; “while x<2:” When x is bigger than 2 or equal, it quits from while loop. [ad_2] solved so simple ask about while loop
[ad_1] To get an array like this, simply use Array.from const additionPerLoop = 1000; const amount = 10000; const res = Array.from({length: Math.floor(amount / additionPerLoop) + 1}, (_, i) => i * additionPerLoop); console.log(res); 0 [ad_2] solved Optimizing a while loop in Javascript
[ad_1] When the scanf(“%i”, &choice); statement is executed, it puts the integer entered by the user, into the int variable choice. However, it also leaves the newline character in the input buffer causing the user input to get thrown off. When the scanf(“%c\n”, &guess); statement is executed, the next character entered is placed on the … Read more
[ad_1] You need to split it up into sections. First: Get positive number double i; double k; Console.Write(“What is your total income : “); while (!double.TryParse(Console.ReadLine(), out i) || i < 0) { if (i < 0) { Console.WriteLine(“Your income cannot be negative.”); } else { Console.WriteLine(“Enter your income as a whole-dollar numeric figure.”); } … Read more
[ad_1] Your inner conditionals don’t make sense with the while. And you have a return statement in the loop, so yes, it only looped once. Start with this import math n, count = (1003, 3) print(“N = ” + str(n)) while count > 0: n = math.ceil((n – 5) / 2) # Update this to … Read more
