Set of multiple choice questions for programming with P8

Question 1. Which one math operation is used to determine the address of the object that the pointer points to:
1. *
2. !
3. &
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); 

 }; 
```
1. '29b'
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
Question 4. When the pointer variable does not contain any address, its value will be:
1. O
2. NULL
3. Both results are correct
4. Both results are wrong
Sentence 5. Symbols specific to the impact on data are called:
1. Jaw
2. Expression
3. Turn
4. Operator

Question 6. What are the results of the following program:

 #include 

 void main () 

 { 

 int x, * p; 

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

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

 };

Question 8. What are the results of the following program:

 #include 

 int change (int * a) 

 { 

 * a = 10; return * a; 

 }; 

 void main () 

 { 

 int i = 5; change (& i); printf ('% d', i); 

 };

Question 9. What are the results of the following program:

 #include 

 void main () 

 { 

 int x, * p; x = 6; p = & x; 

 printf ('% d', x); 

 printf ('% d', * p); 

 };
