Is it possible to send arrays from bash to C++ program?

Question

I wanted to know, if its possible to create an array_of_strings and send it to a C++ program, which has an argument string array_of_strings[]?

Answer 1

Gilles's answer gives you 90% of it, but the rest is on bash to do right.

$ arr=(foo bar 'Hello World!')
$ ./foo "${arr[@]}"

Answer 2

All programs receive an array of strings as its arguments. In C++, the arguments are the argv parameter of the main function. The first element of that array is the name of the program, the others are the arguments that you pass.

$ cat foo.cpp
#include <iostream>
int main (int argc, char *argv[]) {
    for (int i = 1; i < argc; i++)
        std::cout << argv[i] << std::endl;
    return 0;
}
$ g++ -o foo foo.cpp
$ ./foo hello world
hello
world
