How to make one shortcut to execute .cpp file

whenever I want to execute a .cpp in terminal I have to write ./ before it .

And I want to change this "./" to something else .

I found this on another thread :

cr(){
if [ "$#" -ne 1 ]; then
    echo "Usage: cr <file.cpp>"
else
    name=$(echo $1 | cut -f 1 -d '.')
    g++ $1 -o name; ./name
fi

}

It works fine but the thing is that I want to use it with flags like -DLOCAL and some others, how do I make it work?

Because right now I'm using sublime text with some templates and those (templates) require the flags to show the values in terminal .

And also if there is a way to make it work without writing the .cpp extension everytime

(ex : cr A.cpp in cr A)

Thanks !

Edit : Managed to get the flags working but still, is there a way to not write .cpp when running the shortcut?

The command make A will compile and link a A.cpp using default rule g++ A.cpp -o A

Ex. given

$ cat > A.cpp
#include <iostream>

int main(void) { std::cout << "Hello world" << std::endl; return 0; }

then

$ make A
g++     A.cpp   -o A

$ ./A
Hello world
