Can you pass an argument to the main function??

Question

main function in c++ is the starting point of program exectution

Answer 1

In the playground you cannot. If you start you program via a command prompt you would do something like this
MyProgram.exe first

With "first" being the first argument.

In visual studio there is setting to add arguments

Answer 2

Yes this is possible if you use main(int argc, char* argv[]) in your code.
Say your file is named "foo.cpp"
Then, after compiling, you can call it in your console with additional parameters like
./foo test1 test2

Then argc is 3 and
argv[0] : ./foo
argv[1]: test1
argv[2]: test2

But I'm afraid you can't do this in Sololearn
