I pasted your code on https://tio.run/#c-gcc, and here’s the result: main prototype .code.tio.c:3:7: warning: ‘main’ takes only zero or two arguments [-Wmain] int main(int fib) { ^~~~ the main function prototype is int main(void) or int main(int argc, char *argv[]) Since you want user to input a number, you can choose the first form. count … Read more
You can declare global variables but you have to initialize inside main like this: char* vidmem; char* vidmem; int main() { vidmem = (char*)0xb8000; vidmem[0] = ‘x’; vidmem[1] = 0x0f; } 1 solved Can’t use global variables with gcc
Find longest string: ofstream myfile; std::istringstream f(“line1\nline2\nline3”); std::string line; std::string longest = “”; while (std::getline(f, line)) { std::cout << line << std::endl; if(line.length() > longest.length()){ longest = line; } } myfile << << std::right << setw(longest.length()) << “Your Text”; This is my solution 2 solved How to print string containing numbers right-aligned?

Recall that the static variable is shared between all calls to main. Then consider the code as it is executed recursively: int main() { static int i = 5; // 5 if (–i) { // 4 main() { if (–i) { // 3 main() { if (–i) { // 2 main() { if (–i) { … Read more
First off, welcome to the C++ world! Now, let’s move onto your problem. If you take a look at this line, while (name != “Alice” || name!= “Bob”) As others have said, this contains the problem. You are basically saying: while (the name is NOT “Alice” OR the name is NOT “Bob”) Names cannot be … Read more

Firstly, a common mistake in reading 8.5.3p5 is to miss that it has two top level bullet points. You may have accidentally misread the final occurence of “Otherwise” as a third bullet point – but it is in fact a subpart of the second bullet point (also starting Otherwise). char a=”a”; char* p = &a; … Read more

You cannot do it for local variables like this. For member fields you can use reflection; for locals, the simplest approach is to use Dictionary, for example, like this: IDictionary<string,string> vars = new Dictionary<string,string> { {“one”, “find”} , {“two”, “cancel”} }; combobox1.text = vars[“one”]; solved Use of string as an existing variable in c#

First, std::unique_ptr is a class not a struct, so get rid of the struct prefix on the pdfInfo variable declaration. You were probably thinking of this instead: std::unique_ptr<struct Canvas::LoadedPDFInfo> pdfInfo; But even when declaring variables (or type-casting) using actual struct types, you still do not need the struct prefix. C needs that, C++ does not. … Read more
a textreplace isn’t working in my case. i need an error shown up when a user leaves the box when he types more then one \ If this is what you really want you need to use a ErrorProvider. Add one to your form then add the following code to the texbox’s Validating event and … Read more
You are using a cross-compiler for Windows, and you are trying to run the binary on Linux (I assume ubantu is a linux distribution). Just use normal g++ from apt-get install g++. Here’s a GLFW usage example, if you’d like to see some code. GLFW is cross-OS, so it will still work when compiled on … Read more

You should parameterized your query. DateTime doesn’t have any format associated with it, Format is only useful for displaying purpose. OleDbCommand cmd = new OleDbCommand(“Select * From TEST WHERE MatchDate >= @matchDate”, conn); cmd.Parameters.AddWithValue(“@matchDate”, DateTime.Today); // Just date part comparision // Or use DateTime.Now depending on your requirement) OleDbDataAdapter da = new OleDbDataAdapter(cmd); da.Fill(ds); This … Read more
