When you enter a number different than 2 you actually read another line which you do not process: if (answer != 2) { Console.WriteLine(“Wrong answer. Press enter to get your next sum”); Console.ReadLine(); } Your confusion could be because of this line. Change it to: if (answer != 2) { Console.WriteLine(“Wrong answer. Press enter to … Read more
Your second method is actually written incorrectly: you’re adding the .x property of rhs to everything. I’m going to assume that was a simple mistake, and you meant to have the same behavior between the two methods. These two examples call different constructor overloads, which you haven’t included code for. If we can assume that … Read more
you’re getting this error code error: no matching function for call to ‘QStylePainter::drawItemPixmap(QRect&, Qt::AlignmentFlag, QIcon&)’ painter.drawItemPixmap(opt.rect, Qt::AlignCenter, opt.icon); because drawItemPixmap draws… a pixmap. Not an icon. So all you need to do is get the icons pixmap using the pixmap() accessor. change painter.drawItemPixmap(opt.rect, Qt::AlignLeft, opt.icon); to // or whaever size you want painter.drawItemPixmap(opt.rect, Qt::AlignLeft, opt.icon.pixmap(QSize(16,16))); … Read more
So here we go. I will help you with such task. First get list of databases. Then get list of tables (parameter is Connection string, where you should add the name of the database you have choosen in your combobox. public List<string> GetDatabaseList() { List<string> list = new List<string>(); string conString = “Data Source=yourDataSource; Integrated … Read more
This code should work for you. It makes use of the fact, that str is a pointer to the first character of the string. char *str = “Hello world”; /* * Uncomment if `str` could be `NULL`: * * if (str == NULL) { * fprintf(stderr, “Error: invalid string\n”); * exit(EXIT_FAILURE); * } */ while … Read more
You can get the Day and Time in DateTime object (datestr). Check datestr object to get more information such as month, year, ShortTimeString. DateTime datestr = DateTime.Now; datestr.DayOfWeek; //it shows the day ex: monday,tuesday datestr.ToLongTimeString(); //restult will be time ex: “10:18:19 PM” 6 solved How to find just Current time and just day in mvc … Read more
while (i <= 2) { while (i > 0) { a = a + b; i–; <- out the inner while loop when i = 0 } printf(“%d”, a); i++; <- at here, the i==0 each time, so infinity loop } 0 solved Can anyone tell me why this program go to infinite times?
The below code can be an alternative to a for loop. You just need to take care of all parts like initialization, condition, iteration count, etc. int i=0; abc: i++; if(i<10){ printf(“i is %d\n”, i); goto abc; } When a for loop is compiled, the assembler uses goto-like statements to generate assembly code for a … Read more
It sounds like you have a bad design issue in your code more than anything else. First off, why would you want to create a shared_ptr*? That already seems wrong. Then leaking it because you don’t know when other threads will be finished with it? What?? That’s bad. Why not just have two shared_ptr and … Read more
There is no defined situation where strcmp can fail. You can trigger undefined behavior by passing an invalid argument, such as: a null pointer an uninitialized pointer a pointer to memory that’s been freed, or to a stack location from a function that’s since been exited, or similar a perfectly valid pointer, but with no … Read more
You have to use bignum arithmetic which isn’t included in standard C++ library so you either have to write it yourself or use some third party library. About storing specifically – well it could be stored as an array (or vector) of unsigned ints less than 10000 for example which will represent it’s numbers “digits” … Read more
Headers included with one compiler are typically tailored to that compiler implementation and will not necessarily work correctly with a different compiler. So generally speaking you won’t be able use the headers that come with Visual Studio with another compiler. 7 solved Why won’t clang compile this source code that works in VS2012?
The equivalent is std::string or std::wstring declared in the <string> header file. Though you should note that python has probably different intrinsic behavior about handling automatic conversions to UNICODE strings, as mentioned in @Vincent Savard’s comment. To overcome these problems we use additional libraries in c++ like libiconv. It’s available for use on a broad … Read more
hi try this hope its work #include<stdio.h> #include<cono.h> #include<iostream.h> #include<stdlib.h> void main(void) { int a,b; printf(“enter a”); scanf(“%d”,&a); printf(“enter b”); scanf(“%d”,&b); if(a==1 && b<=8) { printf(“you”); exit(0); } else if(a==2 && 5<b && b<=10) { printf(“you”); } else{ printf(“me”); } getch(); } 2 solved multiple conditions in same if statement in C [duplicate]
Dividing int by int yields an int. Dividing float by int yields a float. For int, use %d. For float, use %f. If you mix them up, you get junk. 2 solved How this code is working actually? [closed]
