parameters

问题 In my controllers and other areas where there's a req object, I can access request parameters using req.params('username') . This is fine for normally POSTed data, but I want my API to accept a JSON object in the request body and convert it to parameters that I can still access with req.params() . So for example, if I send this as the POST request body to my controller action: {'username': 'Chris', 'password': 'mypass'} I want to be able to get the username and password using req.params(

问题 For the record I am completely green in C++ and any other programming language for that matter, so if it's possible I'd be happy if you can answer in a way that I can understand :) I have been working on a simple rock, paper, scissors game recently where I have 3 basic functions, one for the user, one for the bot, and one that choose which one wins the game. I know using system("cls") isn't the best way to go, but I'm not planning on using this outside Windows. The final function results()

问题 I'm trying to set up a filter against a "Totals" column in an SSRS report using an expression for the field. I have a multivalued parameter setup with the values value1, value2, value3, and value4 as options. Before the filter, this totals column just simply added the integer values from the different columns. I want to add functionality to where you can check which of the values the user has selected. Similar to below (Pseudo code, because I can't figure out the syntax): =IIF(Parameters!

问题 I have a simulation model using different components. In order to get a quick overview of the used parameters I use the functionality of annotations to display certain model parameters (e.g. m_flow_nominal) via: textString="Nominal Flow Rate = %m_flow_nominal" in the annotation dialog. Which will give out something like Nominal Flow Rate = 5 This is working perfectly fine for parameters that are integers. I also have a parameter that is calculated from other values. Like, let's say the Volume

问题 Yes, I've read this question & answers: Passing an array by reference in C?. I have a similar problem and implemented the same idea from that question. However, I still get an error from the following code: #include <iostream> void FillArray(int** myArray) { free( *myArray ) ; * myArray = (int*) malloc(sizeof(int) * 2); *myArray[0] = 1; *myArray[1] = 2; } int main() { int* myArray = NULL; FillArray(& myArray); return 0; } I got the following run-time error right after the FillArray function
