cofile.s:

.section .data
arr: 
    .long 333
    .long 111
    .long 666

.section .text
.global main
main:
    inc 1(arr)
    int $0x80
    mov $1, %rax
    int $0x80

fl.cpp:

#include <iostream>

int main() {
    //here you need to get an array from assembler
}

Codes are not working. This is just an examplede here.

Answer 1

extern long arr[3];
