using a one line input for array

WHSCT · #1 (**permalink**) November 30th, 2007, 01:12 PM

What I need to do is have input from one line (integers) and then put them into different variables... Let me explain with code:

THEORETICAL CODE:

Code:

#include <cstdlib>
#include <iostream>


using namespace std;

int main(int argc, char *argv[])
{
    int input[6];       //This will be the array for input

    cin >> input[];  //I know this wont work. What I want to do is
                     //the input will be seperated by comas... 
                     //ie: 1,2,3,4,5,6
                     //How can i do this so that the "1"
                     //goes into input[0].. the "2" into input[2]ect??

    system("PAUSE");
    return 0;
}

Get it? after that I take the numbers individually and put them into variables... but that is unimportant.

Thanks for all your help!!

My first reaction would be to recommend building a function that would accept this a pointer to this array, and a pointer to the string input as arguments, something like that.

By using cin.getline instead of cin, you can specify which string array you want to use.

These arguments don't have to be pointers, but I think it's a good habit to avoid passing an array as an argument (the data), to lower the cost on stack memory usage.

But I'm just a newbie in C++ though, so take my recommendation for what it's worth ;)
