c++ - How to create commands with variables to be executed in cmd

Question

Let me specify the question. I want to make commands so when user will type eg. go (something) it will use the go to specify the function and something to find what the program should do when variable equals something . If there is anything unclear, just ask, i know my explanation is strange.

Example:

In program there is a void go(string choice) function with if condition including few variables that can be used through choice string.

User is opening program and typing go and then string. Program goes to function go and if string is included in if loop, then program goes to specific if condition and does what it should eg.:

if(choice == "room")
{ 
//condition being executed
}

Answer 1

So basically you want a specific function to be executed according to a cmd line input? Easy! Create you main function like this:

int main(int argc, char *argv[])

argc is the argument count and argv is the argument value. Google up on this if you need more info, it's widely used. Use an if statement inside your main function that will call the required function according to the value of argv[]. So when you execute your program you'll execute like

exe_file_name go anything

If you want to call multiple functions dynamically during a single execution you could instead do getline(cin,choice);

if(strcmp(choice, "room")) //condition

Answer 2

我认为应该像

if(strcmp(choice , "room")){//condition being executed}
