C++ Without initialization variable

Question

I have got a problem from my friends. The problem is Without initialization of variable how to print 0 to 10?

I know method to print using for loop using initialization

 for(int i=0;i<=10;i++) {
     cout<<i;
 }

Here int i = 0 was initialized. Then how can one print 0 to 10 values without initialization of the relevant variable? It is possible or not?

Answer 1

Your friends should learn to specify their problems more precisely.

int i; // i is not initialized
i = 0; // i is assigned
for( ;i<=10;i++)
{
  cout<<i;
}
