Using atoi to get inputs?

[ECEsasha]

Hello! I'm really new to using atoi and I've only really used it as shown below:

#include <iostream>
#include <cstdlib>

using namespace std;

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

	float r = atoi(argv[1]);
	float i = atoi(argv[2]);

	cout << "The first input is " << r << " and the second is " << i << endl;

}

I compile it and then run it with: ./"test" 2 5
and that would output "The first input is 2 and the second is 5"


If I wanted to have a string display, saying something like "Please enter the first number: " and THEN have the user input a number, how would I go about doing that using atoi?

I've read: http://www.cplusplus.com/reference/cstdlib/atoi/
I'm trying to stay away from using printf since we aren't allowed to use it in my programming methodology class.

Do you mean like :

Please enter the first number : 5 <ENTER>
Five

?

Yup, just like that
