22. (d)
23. (d)
24. (c)
25. (b)
26. (d)
27. (a)
Explanation:
1. (c) %e or %E represent print the number in exponential format.
%e means output has small letter e.
%E means output has capital letter e.
2. (a) before any arithmetic operation small data type convert into higher data type i.e.signedto unsigned.
3. (a) PRINT IN CONNECTED PRINTER DEVICE, OTHERWISE
TURBO C WILL BE HANGED FOR SEARCHING OF PRINTER IN THE SYSTEM.
4. (d) Character is \ has special meaning in c programming.
e.g.
‘\0’ represents octal character.
‘\n’ represents new line character. So we cannot use ‘\’ directly.
5. (b) 8 is not octal digit. octal digits are(0,1,2,3,4,5,6,7).
So ‘\7’ is octal 7
‘\8’ some special character constant.
6. (c) ‘\10’ represent octal 10 i.e. decimal 8 which is ASCII code of backspaces (only one character)
7. (c) ‘\11’ represent octal 11 i.e. decimal 9 which is ASCII code of blank space.
8. (b) ‘\12’ represent octal 12 i.e. decimal 10 which is ASCII code of new line character i.e. send the cursor to next line
9. (c) ‘\377’ is octal character constant.
%o is used to print octal number system.
10. (d) Highest possible character constant is ‘\377’ which is
Equivalent to decimal 255.
11. (d) invalid variable name. goto is keyword in c.
12. (d) invalid variable name. Variable name must star from either alphabet or
under score.
13. (d) invalid variable name. Except underscore there should not be any special character in name of variable event blank space.
14. (a) We can use c++ keyword in variable name in c programming.(But should not use ,why ?)
15. (a) Under score is valid keyword in c.
16. (a) __WORLD__ is valid identifier in c programming language.
But we should not write variable name in the forma like __xyx__,
__TIME__. Why ?
17. (d) __TIME__ is valid identifier in c programming language but it is
Predefine global identifier .So a variable not should not be global
Identifier like __TIME__,__DATE___,__FILE__ etc.
18. (d) After applying any operator in variable name it always give a value.
(type): urinary type casting operator is not exception for this.
It is similar to write
3456=5
It is invalid c statement. Because left side of assignment operator must
Be a variable not any constant.
19. (d) After applying any operator in variable name it always give a value.
(type): urinary type casting operator is not exception for this.
It is similar to write
3456=5
It is invalid c statement. Because left side of assignment operator must

20. (d) After applying any operator in variable name it always give a value.
(type): urinary type casting operator is not exception for this.
It is similar to write
3456=5
It is invalid c statement. Because left side of assignment operator must be a variable not any constant.
21. (d) After applying any operator in variable name it always give a value.
(type): urinary type casting operator is not exception for this.
It is similar to write
3456=5
It is invalid c statement. Because left side of assignment operator must be a variable not any constant.
22. (d) After applying any operator in variable name it always give a value.
(type): urinary type casting operator is not exception for this.
It is similar to write
3456=5
It is invalid c statement. Because left side of assignment operator must be a variable not any constant.
23. (d) we Cannot modify a const object.
24. (c) We can assign address of const object to its pointer.
Underscore is valid variable name.
25. (b) Explanation: Here address of variable a is constant not variable a. So we can modify variable a. Initial value of auto type data is garbage.
26. (d) we Cannot modify a const object.
Here address of variable a is constant not variable a.
27. (a) ‘\11’ represent octal 11 i.e. decimal 9 which is ASCII code of carriage return (return to first position of that line)
