1. first
2. 2
3. 3
4. 4
Question 3. Print results to the screen of the following program:
```
 #include void main () 

 { 

 int ch = 'A'; printf ('% d', ch); 

 } 
```
1. A
2. a
3. 65
4. Other results

Question 4. Result of the following program:

 #include 

 void main () 

 { 

 int i = 98; printf ('% c', i); 

 };

Question 5. Print results to the screen of the following program:

 #include 

 void main () 

 { 

 int i = 5, j = 6; i = i- --j; 

 printf ('% d', i); 

 };

Question 6. The general form of printf () function is: printf ('array of specifications', sequence of expression code); In it, the code set will be:
1. The range of data format codes displayed
2. Cursor of string of characters
3. Character strings are informative
4. All 3 answers above
Question 7. In the following functions, which function is an unformatted function to enter a character from the keyboard
1. scanf ()
2. getchar ()
3. getch ()
4. getche ()
Question 8. In the following functions, which function to enter a character from the keyboard immediately after typing, do not wait press Enter and do not show the screen:
1. scanf ()
2. getchar ()
3. getch ()
4. getche ()
Question 9. Which function reads the character from the keyboard immediately after typing, without waiting for pressing Enter. The characters appear on the screen:
1. canf ()
2. getchar ()
3. getch ()
4. getche ()
Question 10. What is the following screen print result of the program:
```
 #include 

 void main () 

 { 

 int i; 

 for (i = 2; i <= 4; i + = 2) printf ('% 3d', i); 

 }; 
```
