由 人盡茶涼 提交于 2019-12-09 07:57:07
问题 I am learning C and I am studying functions. So, I read that when I implement my own function I have to declare it before the main(). If I miss the declaration the compiler will get an error message. As I was studying this example (finds if the number is a prime number) #include <stdio.h> void prime(); //function prototype(declaration) int main() { int num,i,flag; num = input(); // No argument is passed to input() for(i=2,flag=i; i<=num/2; ++i,flag=i) { flag = i; if(num%i==0) { printf("%d is

问题 I have a problem I can't seem to solve. I created a class function called test and in the function I declared a variable. On the next line I fill the function with a string.

Explain this confusing dojo tutorial syntax for declare

由 梦想的初衷 提交于 2019-12-05 11:42:27
I am reading the syntax for using dojo's declare for class creation. The description is confusing: The declare function is defined in the dojo/_base/declare module. declare accepts three arguments: className, superClass, and properties. ClassName The className argument represents the name of the class, including the namespace, to be created. Named classes are placed within the global scope. The className can also represent the inheritance chain via the namespace. Named Class // Create a new class named "mynamespace.MyClass" declare("mynamespace.MyClass", null, { // Custom properties and

The full error description is as per below: And I found a few similar question posted before: A and B But the question in A and B does not provide detail of problem description (perhaps we prompted the same error message but caused by different reason?

C# Declare a string that spans on multiple lines

由 ▼魔方 西西 提交于 2019-12-04 00:29:15
问题 I'm trying to create a string that is something like this string myStr = "CREATE TABLE myTable ( id text, name text )"; But I get an error: http://i.stack.imgur.com/o6MJK.png What is going on here? 回答1: Make a verbatim string by prepending an at sign ( @ ). Normal string literals can't span multiple lines. string myStr = @"CREATE TABLE myTable ( id text, name text )"; Note that within a verbatim string (introduced with a @ ) the backslash ( \ ) is no more interpreted as an escape character.
