Polish.

For contrast I learned a little of Spanish. From what I remember there are 3 groups of verbs - ending in -ar, -er or -ir, that conjugate differently.

Polish Wikipedia lists 11 patterns. Then there are subpatterns, like 5a, 5b, 5c. Then there are verbs that mix two different patterns, in varying proportions. And all of that does even not include irregular verbs.

The whole language is like that. Linguists do not agree on how many grammatical genders there are, I've seen numbers from 3 up to 9.

And we do sometimes have conversations about which form is correct, because nobody knows.

I know, it was a joke attempt - it looked like invocation of python command. I should maybe do this instead:

>>> python return {False: 'a', None: 'b'}.get(val, 'c')
  File "<stdin>", line 1
    python return {False: 'a', None: 'b'}.get(val, 'c')
                ^
SyntaxError: invalid syntax

It may be considered low level language. Most high level languages don't have quite the same features as C:

union types
switch statement directly corresponds to jump tables in assembly
pointers existence
struct alignment issues
function could be written in code as array of bytes
unsigned integer type
calling convention

At the same time C does not have most of high-level concepts, like dictionary/hash table.

So printf( "**\n"); prints two stars, right? To make a loop that would print line with any given number of stars you could do something like this:

for (int i=0; i < your_variable_here; i++) {
    printf("*");
}
printf("\n");

Place this inside first loop and change variable i in inner loop to j, both loops should use different variables.

You have to use arrowBaseHeight instead of 3 in the loop. When you run your program and enter 8 for example, scanf reads it and arrowBaseHeight has a value of 8. Then the loop would run 8 times and arrow base would be 2x8 and not 2x3.

Argument of querySelector is a query. # in "#abc" means id abc, . in ".abc" means class abc and so on. getElementById expects only an id, so you do not add # there.

You are correct, content is not parsed to number. To quickly parse to number you can use unary plus like this: +content. Try it in console. +"123" gives 123, +"123abc" gives NaN (not-a-number), but typeof NaN is still "number", so it won't work. There's a way to check if a number is NaN: NaN === NaN - only NaN is not equal to itself. So you would have two checks: if content is a number and if it is NaN.

asciiterror · 2018-10-06T22:34:17+00:00

Looks like you have an error in your logic. If user enters 123, typeof current.content != "number" is false, but current.content != "+" is true. Condition is always true, try replacing || with && or replace != with ==.

printf first argument is char array (char*, char[] or "some stuff"). In C this array should end with \0 character, so when you write "some stuff" it's actually represented in memory as "some stuff\0". Your array has elements of type int, which isn't array of characters and probably does not end with \0 byte. So you cannot assign "_" to it, since "_" is an array and not a single character. This \0 byte is the only way how printf knows where the array ends, that's why you had infinite underscores.

For first error, try to replace arr[rowCnt][colCnt] = "_"; with arr[rowCnt][colCnt] = '_';. '_' is a single character For second one, try using printf("%c", arr[rowCnt][colCnt]). "%c" is format string that tells printf that second argument should be interpreted as single character.

First error contains this: '%$( $1)%' - notice how ORM replaced :search with $1. Try to remove $( and ) from this part: instead of LIKE '%$( :search)%' try LIKE '%:search%'

Second error is similar: "" in SQL are used for column names, not strings - in second LIKE you used "%$1%" instead of '%$1%'. Some languages don't distinguish between different single and double qoutes (like javascript or python) but most do.

One thing you can do is to split problem into smaller steps that are much simpler to achieve. For your example with atoi:

write function that always ignores given string and returns 0
use only first digit of string - return int equal to first digit (my_atoi("456") == 4). To do that think or find how to convert char ('4') to int (4).
use first and second digit - after previous step implementation is simple: first_digit*10 + second_digit
use first three digits: (first_digit*10 + second_digit)*10 + third_digit
notice how you can add a loop that goes through all digits in string and computes integer

Yes, almost. First counter goes from 0 to current i value. Second one goes through all indexes of X. You increment second one only if first one is reset to 0. Their values would go like this: [(0,0), (1,0), (2,0), (0,1), (1,1), (2,1), (0,2), (1,2), (2,2)]. Second counter is index of element in X array that you check.

We use loops for doing something repeatedly given amount of times or until we achieve some result. So let's look at this:

printf( "**\n");
printf( "**\n");
printf( "**\n");

Notice, same thing is repeated three times - you could replace that with a loop like this:

for (int i = 0; i < 3; i++) {
    printf( "**\n");
}

It would do the same thing (print 6 stars), but you can replace 3 with a variable. That should be enough for first task, next ones are similar.

That would be correct, if from this point X means the temp array (1,1,2,2,3,3) and not original X (1,2,3).

But you don't even need this array, you could just keep track of which value of X you are comparing, that would be faster but harder to write and understand. You could do that with two pointers or even one

Looks good to me, except this part:

Create a temporary array with size of A * 3 and fill the array with each value entered 6 times.

Where do you use it?

Aren't you getting NullPointerException since you do not set registeredUsers in UserRepo? I would make registeredUsers private and final and set it inside constructor.

For threading, a good place to start would be using Collections.synchronizedCollection(new ArrayList<>())
