4. Other results
Question 2. Suppose when running the program, we type from the key: '29h b'. Print results n and c respectively will be:
```
  #include void main () 

  { 

  char c;  int n; 

  scanf ('% d% c', & n, & c); 

  printf ('% 3d% c', n, c); 

  }; 
```

2. '29h b'
3. "29h '
4. Other results
Question 3. When declaring an array, we initialize the array as follows: int x [3] = {4,2,6}; Mean:
1. x [1] = 4, x [2] = 2, x [3] = 6
2. x [0] = 4, x [1] = 2, x [2] = 6
3. Not declared correctly
4. After all other

  { 

  int x, * p; 

  x = 3;  x = 6;  p = & x; 

  * p = 9;  printf ('% d', x);  printf ('% d', * p);  printf ('% d', x); 

  };
