Compile the following program with [ARM embedded toolchain](https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads): ```cpp #include int main(int argc, char* argv[]) { std::cout << "argc: " << argc << "\n"; std::cout << "argv: \n"; for (int i = 0; i < argc; i++) std::cout << " [" << i << "] " << argv[i] << "\n"; return 0; } ``` ``` $ $CXX --version arm-none-eabi-g++ (GNU Arm Embedded Toolchain 10-2020-q4-major) 10.2.1 20201103 (release) Copyright (C) 2020 Free Software Foundation, Inc.
