I need help converting this C++ file to assembly code. I know I have to use g++ -S filename.cpp but I have no clue on where the command goes or how to execute the command to get my s file that shows my assembly code. I created a new file with the command in it but I know that is incorrect.

#include
using namespace std;

int main()
           {
int width=10;
int height=5;
int area;
area = width * height;

cout<     return 0;
}
