2. What is argv[0]?

A) This syntax is illegal

B) The first argument to the program

C) The name of the program

D) The number of arguments to the program

Answer 1

The correct option is D) g++ main.cpp -o funcdef.cpp func

Explanation: If we are going to compile a main.cpp, while our main() in main.cpp uses a function defined in another file funcdef.cpp, the command which is correct is g++ main.cpp -o funcdef.cpp func. This is because the base command for the Gnu C++ compiler is "g++".

For example :

g++ main.cpp

This command is responsible for creating an executable program.

2.

The correct option is C) The name of the program

Explanation: argv[0] is the command line argument which is responsible for holding the name of the program.
