Command line Arguments in C++

Question

Can somebody please briefly explain me about (int argc , char* argv[]) used in c++.

I tried to learn it from some YouTube tutorials but didn’t quite get it.

Answer 1

int main(int argc, char* argv[]){
cout << argv[1] << endl;
}

----

*compile code*

in the commandline:
yourcode.exe hello

output:
hello

Answer 2

Google your IDE and what type of executable it generates. Then you can run the executable the way Cat Sauce said.

Answer 3

Yes! This is something that took a while for me to get too. C++ can get compiled on the command line using a compiler program like GCC. When you compile, the output is an executable binary that you can run with arguments. Example:

g++ main.cpp -o exec
g++ is just a way you can run GCC

./exec arg1 arg2

arg1 and arg2 will be the 2nd and 3rd elements in the argv array. The first element is the program name itself
