[ad_1] If you want more than one economy, then you need a property that keeps track of which economy each worker belongs to. Then you can just use that reference to subtract the wage from the correct economy: public class Worker { public Economy InEconomy { get; private set; } public int Wage { get; … Read more
[ad_1] Vectors in functions, how to create find and erase function for deleting indexes based on user input (string)? [duplicate] [ad_2] solved Vectors in functions, how to create find and erase function for deleting indexes based on user input (string)? [duplicate]
[ad_1] Maybe your method should look like this : public boolean checkSuper(int num) { int n1; int n2 = num; while(num > 0) { if(num % 10 == 0) { return false; } n1 = num % 10; if(n2 % n1 == 0) { num = num / 10; } else { return false; } … Read more
[ad_1] Your calculation of the complex modulus is incorrect. float Complex::getAbsoluteValue() const { return sqrt(real * real + imaginary + imaginary); } You’ve since removed this section of your post, but it should say float Complex::getAbsoluteValue() const { return sqrt(real * real + imaginary * imaginary); } [ad_2] solved Drunk Mandelbrot implementation [closed]
[ad_1] Upto my knowledge, most common time complexity notation is Big-O, I’ll share same in this answer. Time complexity is O(1), with an assumption that Math.Pow calculation is O(1) and .ToString() method is O(1). It is O(1) because each step will be executed only once. In gerenal, if we take .ToString().Length time complexity into account … Read more
[ad_1] x = (x > 250000 && x < 500000) ? (x / 100) * 10 : ((x > 500000 && x < 1000000) ? (x / 100) * 20 : ((x > 1000000) ? (x / 100) * 30 : x)); Ternary operator of the form (conditional) ? expr1 : expr2 should be read … Read more
[ad_1] Given what you have posted, Example 1 int d; d=0; d=a+b; /* print d+c+e;*/ printf(“%i\n”, d+c+e); Example 2 /* print a+b+c+e; */ printf(“%i\n”, a+b+c+e); Which is faster is tricky, if your compiler optimizes d away in Example 1 they are equivalent. On the other hand, if your compiler can’t determine that d=0 is discarded … Read more
[ad_1] It’s a bound parameter marker. You’ll need to list all bound parameters in the Parameters collection. Using bound parameters as opposed to just constructing the SQL text directly helps with security (prevents injection attacks) and performance. [ad_2] solved What does @ mean when creating a SQL query with C#? [duplicate]
[ad_1] It depends how many queries you can expect, and the number of identical queries you can expect. One approach is to “memoize” queries, simply to store each query and result, and look that up before doing more serious work. A more problem-specific approach – probably what your teacher is after – is to compute … Read more
[ad_1] Looks like my previous answer was a bit terse… cout << results[rand()%(sizeof(results)/sizeof(results[0]))] << endl; could be broken down to int num_elems = sizeof(results)/sizeof(results[0]); int randomIndex = rand() % num_elems; int randomValue = results[randomIndex]; cout << randomValue << endl; In slightly more detail: sizeof(results)/sizeof(results[0]) calculates the number of elements in the array results. (Note that … Read more
[ad_1] The program builds a new number reversing the order of decimal digits of the entered number. For example if 123 was entered then the result will be 321. By the way why do not to compile it and see the result?:) 0 [ad_2] solved What kind of task will be done with the following … Read more
[ad_1] Due to python nature (being interactive) you can use function like dir() and help() but there no such thing in c (since it would not even make sense). to get an explanation about a function or a library: since this is about the standard library take a look at: the standard specification ask the … Read more
[ad_1] There are basically three possible reasons for this error. I can’t tell which one applies because you didn’t really post any details in the question. One, your secret code has a subtle bug that wasn’t tripped with previous listings. Resolution: Debug your code. Two, eBay made a change to their postage policy or listing … Read more
[ad_1] Instead of splitting the string and then putting it back together again, you can just walk the string one character at a time, and build a result string from it. If you compare the current character with the previous character, you can determine whether or not to add a closing tag first, or just … Read more
[ad_1] You use two separate connection objects: SqlConnection con1 = new SqlConnection(@”Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\sms.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True”); SqlConnection con2 = new SqlConnection(@”Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\sms2.mdf;Integrated Security=True;Connect Timeout=30;User Instance=True”); [ad_2] solved How To Access Two Databases in a Single connection String in C#?
