Reading inputs from Keyboard in Objective C

Question

I am new to Objective C. But I know C/C++. I want to accept inputs from keyboard, let assume that its a program for adding 2 numbers.

So can I use scanf("%d %d",&a,&b); ?

If you are creating a command line util, yes you can. If it is a normal app, pls use the UI elements such as NSTextField to read he input. What exactly is your requirement? — Shanti K, Apr 07 '14 at 09:39
@ Shanti K: The following is my code is this correct?#import int main () { /* variable definition: */ int a, b; int c; NSLog(@"Enter values for A & B: "); scanf("%d %d",&a,&b); c = a + b; NSLog(@"value of c : %d \n", c); return 0; } — Arun, Apr 07 '14 at 09:42

objective C is a superset of regular C , so you can use all the C functions like scanf() or getchar() and similar!

Yes you can. You can also rename yours file to .mm and write:

#include <iostream>
using namespace std;

cin>>a>>b;

Hi actually what is the use of "using namespace" – Arun Apr 07 '14 at 17:19
@Arun, cin is defined in std namespace, so without `using namespace std;` you should write `std::cin>>a>>b;`. – Cy-4AH Apr 07 '14 at 18:40
