The first problem is that you haven’t declared your function before using it in main(). Provide a declaration or prototype before calling it. double avg(int a[], int *n); int main() { … Second, in the first implementation, you are not storing the return value of the function avg (arr, & size) ; // useless statement … Read more
Well the simple thing is here you would be good to go even if you didn’t use casting in these 2 statements char** sa = (char**)a; char** sb = (char**)b; Because conversion from void* to char** is implicit. This would also be fine (provided you assign it to correctly qualified variable name). const char** sa … Read more
If I understand you correctly, you have a structure containing several members of different types and you are looking for a way how you could compare instances of this struct. It could look the following way: struct X { std::string s; char c; int i; bool operator==(const X& ref) { return s == ref.s && … Read more
In bool StatsList::NewGrade(ListType grade) there are a couple problems. i needs to persist from call to call otherwise it will always be set to 0 at the beginning of the function. I recommend giving it a more descriptive name like listindex and making it a member variable. There is no return true. The logical place … Read more
Change your method to private string NumbersToWords(int number) { string word = “”; if (number == 8) { word = “Eight”; } return word; } Previously you did not return a value, indicated by void. 3 solved C# convert a number into words
circleType::setRadius; double radius = circle.getRadius; The first line doesn’t do anything. The second line tries to set a variable of type double equal to a function. Perhaps you want to call these functions? This is what non-operator member function calls look like in C++: double area = circle.areaCir(radius); double circumferance = circle.circumCir(radius); circle.printCir(circumferance, area); So … Read more
You might set your Matrix properties based on the Dimension like class Matrix implements MatrixInterface { private Integer width; private Integer height; void GetSize(Dimension dim) { this.width = dim.width; this.height = dim.height; } } // Please note that this code isn’t clean. Or maybe the Getter is in fact a Setter. class Matrix implements MatrixInterface … Read more
Read up on the return keyword. An example of getters and setters methods can be found at How do getters and setters work?. A setter method is a method which sets a variable in your class. Getter methods give the variable to whatever calls the method. Getters: In a main method: String s = MethodClassProject.getBrand(); … Read more
public void checkout(String answer,int missedcallcount) Declaration of this method shows, that you need to pass two parameters to call it properly – in this example, if you want to call this method you need to pass to it String as a first argument, and int as a second argument. Here is an example of correct … Read more
void is not a complete type. It is only used either in a function definition to state that it either takes no parameters or returns no value, or as a generic pointer i.e. void *ptr. As such, a variable of type void cannot exist. solved C: error: array has incomplete element type ‘void’ [closed]
Boolean values in Swift are true and false, YES and NO is used in Objective C. So in your stopRunning method for instance, you should write: @IBAction func stopRunnng(sender: UIButton) { tmrRun invalidate() btnGo.userInteractionEnabled = true btnStop.userInteractionEnabled = false sliSpeed.userInteractionEnabled = true } (sidenote, you don’t need the ; in Swift either) About the void … Read more
