As you saw, your function read_ins is always outputting the first line of your file program.txt. This is because each time you open the file using fopen, the read cursor is starting from the beginning of the file. To change this behavior, you should open the file and give the FILE* as an argument of … Read more
The problem is if you save the time in cookie just before refresh and retrieve it after page loads it may not match the real current time because page may take arbitrary amount of time to refresh, 1st time it may be 1 sec 2nd time may be faster and take 0.5 sec due to … Read more
SUM does not take two parameters like you did in sum(fleuge1.Preis,fleuge2.Preis) sum is an aggregate function , meant to sum all the values on a column, if you want to sum two values from a two distinct sets just do fleuge1.Preis+fleuge2.Preis if you want to post errors on stack overflow you can just copy them … Read more
A java.io.File object does not represent a file. What it actually represents is a file system pathname; i.e. a name for an object in the file system that may or may not exist. So your program is not “receiving” a file at all, and the only things that you could do with the object that … Read more
You can implement it using mapM_/traverse_ or the flipped argument versions: forM_/for_. I prefer for_ since it looks more like the “enhanced for-loop” from languages like Java. import Data.Foldable (for_) myPutStr :: [(Double,String)] -> IO () myPutStr vals = do for_ vals $ \(num, str) -> do putStr str putStr “: ” print (num * … Read more
Your code is almost correct – you are showing the result in the BetAmount field so no change is visible. Change your code to: document.getElementById(“PotentialGain”).value = ish; Here’s a working demo. I changed the event to onkeyup as onchange only happens on blur – i.e. when a field loses focus. solved Calculate one variable based … Read more
The fundamental issue is that you’re creating multiple JSON strings (json_data = (json.dumps(response, indent=2))) and then adding them to an array (json_arr.append(json_data)), and then converting that array to JSON (json.dump(json_arr,outline)). So the result is a JSON array of strings (containing JSON). You don’t want to create a string before adding to the array, just include … Read more
When you call a function recursively, they add the new function to a stack until have a final result (return). When it occurs, you go back return by return in the stack. An Execution example: First Round wacky(4, 6): 4 <= 1? No, so call wacky(4 – 1, 6 – 1) Second Round wacky(3, 5): … Read more
You can turn a string into code by using pythons eval function, but this is dangerous and generally considered bad style, See this: https://stackoverflow.com/a/661128/3838691. If user can input the string, they could input something like import subprocess; subprocess.check_call([‘rm’, ‘-rf’, ‘*’], shell=True). So be sure that you build in reasonable security into this. You can define … Read more
Hi!This is your code without errors! So, I changed somethings, I’ll list them to get clearer. To use “Name” and “Id” in more than one method, it is easier if they are global variables. When calling the “test” method you need to pass the values, so in the “entry” method the values are passed. The … Read more
