The postfix ++ operator increments the value of a variable after the statement it’s in has been executed. According to C’s precedence rules, the expression will be evaluated something like this: while (*(dst++) = *(src++)); Which will basically: Set the character dst points to to the character src points to. Increment both dst and src … Read more
Here’s the offending code in question: if (xflg) index = m * nxy + l*nx + k; fprintf(stdout,”%.1f”,index); else index = m * nxy + k*ny + l; The “if” and “else” sections of this if statement originally had one line each, so adding braces wasn’t strictly necessary. But when you added the call to … Read more
If you give him your source code, no technical measures can stop him from stealing the source code. If he were local to you, you could require him to use a locked-down computer in your own office, but I don’t think that is an option for you. If your app has substantial non-code assets (graphics, … Read more

There are many ways to implement Arrays::toString, here are a few examples: import java.util.Arrays; import java.util.StringJoiner; import java.util.stream.Collectors; public class ArraysToString { public static void main(String[] args) { int[] array = {10, 16, 181, 200, 410, 68, 31, 555, 161, 313}; System.out.println(Arrays.toString(array)); System.out.println(arrayToString1(array)); System.out.println(arrayToString2(array)); System.out.println(arrayToString3(array)); System.out.println(arrayToString4(array)); // [10, 16, 181, 200, 410, 68, 31, 555, … Read more
You want to put the second input line – to take the configuration1 into a for loop to run T number of times and display it. public static void main(String[] args) { int T, N; System.out.println(“Enter number of test cases: “); Scanner in = new Scanner(System.in); T = in.nextInt(); String configuration1; for (int i = … Read more
Have you tried anything? There’s lots of ways to do what you’re trying to do. Some more peprformant than others, some easier to write… This would be a quick way to implement what you need: func PrintStr(m map[string]interface{}) { parts := make([]string, 0, len(m)) for k, v := range m { parts = append(parts, fmt.Sprintf(“%s=%v”, … Read more
Make sure that the file_get_contents is successful (not returning false) before proceeding to write (otherwise the counter will be re-set as 1, which is not desirable) Hence: <?php $count=”counterfile.txt”; $var1=file_get_contents($count); if ($var1!=false){ file_put_contents($count, (1+$var1) ,LOCK_EX); } ?> Alternatively, you may use a db approach (increment a field value by one each time) solved A trivial … Read more
it’s equivalent to if (b) { return s1; } else { return s2; } Edit: As Alexey pointed out, I should clarify. return here isn’t the return from your specific function it’s just saying that the statement (b ? s1 : s2) will evaluate to either s1 or s2 based on the value of b. … Read more
To replace the last 2 digits with some characters, firstly convert it to a string and then, using the slice() method, append the characters. You can read more about the slice() method in its MDN Documentation. let numberAsString = Math.random().toString(); //your number as a string let result = numberAsString.slice(0, -2) + ‘**’; //cut and append … Read more

test2.hpp and test.hpp both #include test1.hpp. If the scope of test1_hpp is the whole application, as far as I understand, there can only one include test1.hpp success. Because once included, test1_hpp is defined. The compiler works on translation units (think: individual .cpp files) not the whole application (think: executable). What you call “the scope of … Read more
