You should make sure your indentation is uniform (always 4 spaces). Starting with if Submit == “yes”:, your lines have one extra space. This will be easier to do if you use a better IDE than IDLE, which will automatically highlight and label problems like this. Some good alternatives are Spyder (which is free), and … Read more
Function argument is missing in findHighest() function. The function deceleration is void findHighest(double sale[]); You are not supplying argument double sale[] Thus replace the line findHighest() [the line before system(“PAUSE”) statement ]with findHighest(sale) 2 solved Too few arguments to function error? (C++) [closed]
that’s because the self variable has to be explicitely given to methods in python. As you write it, are you expecting python to read your mind so it guesses that self shall be something from a class your function is not related at all with? So to have it bound you need: add self to … Read more
This was a trick question: you are supposed to use recursion, but unless you are barred from using loops, a classic solution with a for loop can be made to comply with the recursion requirement. Here is a function isPrime that has a single argument and uses a classic loop and recursion to test prime … Read more
I just had to place the cpp file name in the Android.mk file… This is my first time so sorry… Fixed code: C++ #include <string.h> #include <jni.h> extern “C” { JNIEXPORT jint JNICALL Java_net_pixeldroidof_addonedit_MainActivity_getScreenY(JNIEnv* env, jobject thiz) { int number = 30; return number; } } Java public native static int getScreenY(); //And you can … Read more
It seems it was some trouble within eclipse. I right clicked one of those functions, selected Source->Add includes and it solved the problem (but didn’t added any header). I hope this can be helpful for someone else solved C Implicit declaration differs from internal function declaration
In C, string operations cannot have a convenient interface, because of memory management. If a function receives a string, and converts it to another string, you should decide how to declare its interface. The simplest interface is in-place (strtok uses it); you can use it only if the output is somehow smaller than input: void … Read more
What happens here? You originally call the function with k = 7. The function sees that the given value k = 7 is > 0 and thus calculates 7 + the result of the function if called with 6. In order to determine the latter, it calls itself with k = 6. The function sees … Read more
You almost got it, change it to like this var grades = [100, 90, 100, 50, 80, 60]; function countFailing(gradesArr){ var counter = 0; for (var i = 0; i < gradesArr.length; i++){ if (gradesArr[i] < 70 ) counter++; } return counter; } alert(countFailing(grades)); DEMO HERE solved How to make a function take in an … Read more
Sorry, but I didn’t find a design simpler than that. You could, make a class that owns both a thread, and a weak_ptr to itself, to be a “holder” that the callable can see it safely, because the callable will still exists even if the object is destructed. You don’t want a dangling pointer. template<typename … Read more
How is value getting retained even after function completing execution? Undefined behavior (UB). It might appear to “work”, but that is not specified to be so by C. fun(&ptr); runs fine, yet printf(“%p”,ptr); is UB as the value ptr is no longer valid. Many systems will tolerate this UB. De-referencing ptr, with printf(“%d\n”,*ptr); is even … Read more
When in doubt, just break it down. The tree flow is actually counter-intuitive to the actual control flow, but once you understand the sequence of calls, it becomes clearer. The thing to understand here is that you keep breaking down a larger computation to a sum of smaller computations, and you stop when you hit … Read more
CREATE FUNCTION get_id(NAME IN Courses.NAME%TYPE ,COURSE_ID_O[] OUT ARRAY ) RETURN COURSE_ID_O BEGIN IF NAME LIKE ‘_J%’ OR NAME LIKE ‘_Z%’ THEN SELECT COURSE_ID INTO COURSE_ID_O FROM COURSES WHERE COURSE_NAME=NAME ; ELIF NAME=” OR NAME=NULL THEN DBMS_OUTPUT.PUT_LINE(‘Please enter a valid string.’); END IF EXCEPTION WHEN NO_DATA_FOUND THEN DBMS_OUTPUT.PUT_LINE(‘No record found If it is blank or null: … Read more
There are no objects here that I can see. You’re using C++ as “a better C”. It’s been a long time since I’ve written C or C++, but I think you want something more like this. I’ve taken the meat out of the main to emphasize my point: #include <iostream> #include <cmath> using namespace std; … Read more
I would rewrite the main function to be something like: def GetStudentInput(): score = 0 for i in range (4): print(“Mrs Pearson’s Class Test Score Data”) name = CheckStringInput(“What’s Your Name: “) score += CheckNumericInput(“What’s Your Score: “) print(score) This eliminates the need for an extra function and avoids using a list since you don’t … Read more
