Set of multiple choice questions about programming with P11 prize

Instead of going to the centers to learn about programming, you can completely learn at home with extremely useful multiple-choice questions that the Network Administrator summarized below.

Question 1. What function clrscr () is:
1. As a function to delete the entire screen, after deleting, the cursor will be on the left side of the screen
2. Used to clear the keyboard cache
3. A function to delete characters located on the left of the cursor
4. A function to delete characters located to the right of the cursor
Question 2. What are the results of the following program section:
```
 char c; int n; 

 scanf ('% c% d', & n, & c); If typing: 'r 45'. 
```
1. n = 45, c = ''.
2. n = 45, c = 'r'.
3. Error while building the program
4. Other results
Question 3. Function scanf ('% [^ n]', str); Similar to the following command:
1. getch ();
2. getche ();
3. getchar () macro;
4. gets (str);
Question 4. For the following program section:
```
 #include 

 #include void main () 

 { 

 char c; clrscr (); 

 because c = getchar (); while (c! = '*'); getch (); 

 }; 
```
The requirements of the above paragraph are:
1. Enter 1 character until you see the character '*'.
2. Enter the characters until you see the '*' character.
3. Enter the characters '*'.
4. Error while building the program
Question 5. What are the results of the following program:
```
 #include 

 void main () 

 { 

 printf ('% d', 3 6); 

 }; 
```
1. 0
2. first
3. true
4. Other results
Question 6. The '++ n' operator is understood:
1. The value of n decreases after its value is used
2. The value of n decreases before its value is used
3. The value of n is increased after its value is used
4. The value of n is increased before its value is used
Question 7. The 'n--' operator is understood:
1. The value of n decreases after its value is used
2. The value of n decreases before its value is used
3. The value of n is increased after its value is used
4. The value of n is increased before its value is used
Question 8. Which one-sided operation is used to determine the value at the address of the pointer pointing to:
1. !
2. &;
3. *;
4. Other results
Question 9. Subtracting 1 pointer with an integer will be:
1. An integer
2. A pointer of the same type
3. Both results are correct
4. Both results are wrong

Question 10. What is the result of the following code:

 Employeestruct Employee struct {char Code [], name []; long Salary;};Employee e1= { 'E089', 'Hoang so', 12000}, e2=e1; long Salary;}; Employee e1 = {'E089', 'Hoang so', 12000}, e2 = e1; printf ('% ld', el.Salary + e2 -> Salary);
