In many languages such as C, C++, and Java, the main method/function has a return type of void or int , but not double or String .
Strings in C are arrays of char elements, so we can't really return a string - we must return a pointer to the first element of the string. All forms are perfectly valid. Note the use of const , because from the function I'm returning a string literal, a string defined in double quotes, which is a constant.
No, we can't return string from Main method. The entry point can optionally only return an int value.
Use the std::string func() Notation to Return String From Function in C++ Return by the value is the preferred method for returning string objects from functions. Since the std::string class has the move constructor, returning even the long strings by value is efficient.
I would like to return a string variable from my Main() method. I've returned int variables. But I'm not sure if it's possible to return a string variable from Main() when you exit the program?
Any ideas?
Here is my int code:
public class Program
{
/// <summary>
/// The main entry point for the application.
/// </summary>
[STAThread]
static int Main()
{
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
int error = 1;
return error;
}
}
If I change int to string, I get this error: Program does not contain a static 'Main' method suitable for an entry point. So obviously this is not allowed. What is the correct approach?
