cin

Question

I am testing the cin operation , i have tried to insert value for two different variables, it gave the chance to insert the value for the fist one but the other one gave me a random value, what is the wrong with my code please?

# include <iostream>
using namespace std;

int main ()
{
int a;
int b;

cout << "please enter a's value:\n";
cin >> a;
cout << a << endl;
cout << "please add b's value: \n";
cin>> b;
cout << b;
return 0;

}

knowing that i have only inserted 5 at the first time the result was as follows :

please enter a's value:
5
please add b's value:
8

from where the value of 8 has been extracted ??

Answer 1

you have to enter both values when you start the program in SL, else it will pull some garbage value out of memory

Answer 2

I think it's problem with compiler, try same code on some PC IDE like CodeBlocks, and see will it work. Probably it will.
