int main(int argc, char** argv)
Copy

argc means "argument count", how many arguments it must receive
argc starts counting on 1 as the code execution itself (i.e ./filename)
Meaning if we give ./test Hello, then argc will be a value of 2

argv means "argument vector", this is where we store the arguments.
argv[0] is the code execution itself (i.e ./filename)
Overall, we have a default of two arguments in argv
