Question

[THIS SHOULD BE WRITTEN IN C++]

The first argument, usually called argc, tells the program how many command line arguments were passed to the program on its invocation. The second argument, argv, is an array of strings containing the arguments themselves.

Write a main which prints out the arguments passed to the program. For example, when I run my program like this:

./prog apples bananas oranges

it outputs:
Argument #0 is ./prog
Argument #1 is apple
Argument #2 is bananas
Argument #3 is oranges 

Answer 1

#include <iostream>
using namespace std;

int main(int argc, char** argv)
{
for (int i = 0; i < argc; ++i){
cout << "Argument #"<<i<<" is "<<argv[i] << "\n";
}
return 0;
}
