Following are the major classes of data types in C language:

1. Primary data types: Also known as fundamental/basic data types. All C compliers support four basic data types namely: integer(int), character(char), floating(float), and double precision floating point (double). Then there are extended data types such as long int, double int.

2. Derived data types: also known as secondary or user-defined data types. These data types, derived from basic data types, include arrays, pointer, structure, union, enum etc. 

Correct option- (C) 61 

Correct option- (A) 31

Correct option- (B) Stack

Explanation:-

For implementing recursive function, stack is used as a data structure.  

Recursive procedures are implemented by using stacks data tructure. 

Correct option- (C) n*(n-1)/2. 

(C) no cycle of odd length. 

Correct option- (D) more than n(n-1)/2

Function declaration and Function definition: 

A function declaration contains the name of the function, a list of variables that must be passed to it, and the type of variable it returns, if any. For example in the following program in line 2, the function cube is declared. The variables to be passed to the function are called arguments, and they are enclosed in parentheses following the function's name. In this example, the function's argument is long x. The keyword before the name of the function indicates the type of variable the function returns. In this case, a type long variable is returned. The function itself is called the function definition. In the following example, a function cube is defined from line 13 to 18.A function definition has following several parts: 

•Function header: The function starts out with a function header on line 13. The function header is at the start of a function, and it gives the function's name, the function's return type and describes its arguments. The function header is identical to the function declaration minus the semicolon.

• Function Body: The body of the function, lines 14 through 18, is enclosed in braces. The body contains statements that are executed whenever the function is called. Local variables are declared within a function body. Finally, the function concludes with a return statement on line 17, which signals the end of the function and it passes a value back to the calling program. 

The following program uses a function to calculate the cube of a number.

1: #include 

2: long cube(long x); 

3: long a, result; 4: main() 

5: { 

6: printf("Enter an integer value: "); 

7: scanf("%d", &a); 

8: result= cube(a); 

9: printf("\nThe cube of %ld is %ld.\n", a, result); 

10: } 

11: 

12: /* Function: cube() - Calculates the cube value of a variable */ 

13: long cube(long x) 

14: { 

15: long y; 

16: y = x * x * x; 

17: return y; 

18: } 

Correct option- (A) AB^C*D-EF/GH+/+

Correct option- (A) 9 edges

Correct option- (A) indexed sequential search

Explanation:-

The search technique for searching a sorted file that requires increased amount of space is indexed sequential search. Because in this search technique we need to maintain a separate index file which requires additional storage space.  

Correct option- (D) 4 

Top down Design:

A top-down approach is essentially breaking down a system to gain insight into its compositional sub-systems. In a top-down approach an overview of the system is first formulated, specifying but not detailing any first-level subsystems. Each subsystem is then refined in greater detail, sometimes in many additional subsystem levels, until the entire specification is reduced to base elements. In short the top down approach means decomposing of the solution procedure into subtasks. This approach produces a readable and modular code that can be easily understood and maintained. Top-down programming is a programming style in which design begins by specifying complex pieces and then dividing them into successively smaller pieces.

Eventually, the components are specific enough to be coded and the program is written. The technique for writing a program using top-down methods is to write a main procedure that names all the major functions it will need. Later, the programming team looks at the requirements of each of those functions and the process is repeated. These compartmentalized sub-routines eventually will perform actions so simple they can be easily and concisely coded. When all the various subroutines have been coded the program is done. 

A pre-processor is a program that processes the source code before it passes through the compiler. It operates under the control of preprocessor directive. These are placed in the source program before the main. 

To define a macro, # define statement is used. This statement, also known as macro definition takes the following general form: 

#define identifier string

The pre-processor replaces every occurrence of the identifier in the source code by the string. The preprocessor directive definition is not terminated by a semicolon. For example 

#define COUNT 100 will replace all occurrences of COUNT with 100 in the whole program before compilation. 

Correct option - (A) Insertion sort 

If-else statement: When there are multiple conditional statements that may all evaluate to true, but we want only one if statement's body to execute. We can use an "else if" statement following an if statement and its body; that way, if the first statement is true, the "else if" will be ignored, but if the if statement is false, it will then check the condition for the else if statement. If the if statement was true the else statement will not be checked. It is possible to use numerous else if statements to ensure that only one block is executed. 

#include <Stdio .h>

void main()

{

int age;

printf( "Please enter your age" );

scanf( "%d", &age );

if ( age < 100 ) {

printf ("You are pretty young!\n" ); }

else if ( age == 100 ) {

printf( "You are old\n" );

}

else {

printf( "You are really old\n" );

} 

}

Switch case statements are a substitute for long if statements that compare a variable to several "integral" values ("integral" values are simply values that can be expressed as an integer, such as the value of a char).The value of the variable given into switch is compared to the value following each of the cases, and when one value matches the value of the variable, the computer continues executing the program from that point. The condition of a switch statement is a value. The case says that if it has the value of whatever is after that case then do whatever follows the colon. The break is used to break out of the case statements. Break is a keyword that breaks out of the code block, usually surrounded by braces, which it is in. In this case, break prevents the program from falling through and executing the code in all the other case statements.

#include<stdio .h>

#include<con. h>

void main()

{

int flag;

printf( "Enter any value\n" );

scanf( "%d", &flag );

switch ( flag ) {

case 1:

printf( "It is hot weather!\n" );

break;

case 2:

printf( "It is a stormy weather!\n" );

break;

case 3:

printf( "It is a sticky weather!\n" );

break;

default:

printf( "It is a pleasant weather!\n" ); 

break;

}

getch();

}

A structure for an employee and a function to display the details of an employee:

struct employee

{

int emp_code;

char emp_name[30];

char emp_address[50];

char emp_ph_num[10]; int no_of_dep;

allEmployees[100],b;

void display()

{

int ctr=0;

fp=fopen("employee.c","r");

rewind(fp)

while(fread(&allEmployees,sizeof(allEmployees[i]),1

fp)==1)

{

ctr++;

clrscr();

heading();

printf("\n\n\n\

Following are the details :-");

printf("\n\n\tRecord #%d",ctr);

printf("\n\n\t\tCode : %d",allEmployees[i].emp_code)

printf("\n\n\t\tName : %s",allEmployees[i].emp_name)

printf("\n\n\t\tAddress : %s",allEmployees[i].emp_address)

printf("\n\n\t\tPhoneNumber:%s"allEmployees[i].emp_ph_num

printf("\n\n\t\tNumber.Dependents

%s",allEmployees[i].no_of_dep);

printf("\n\n\n\n\t\tPlease Press Enter...");

getch();

}

}  

Correct option - (C) # undef

Explanation:-

The preprocessor directive #undef OKAY would cause the definition of OKAY to be removed from the system.  

The characters which when used with output functions like printf( ),putc(),put() etc. helps in formatting the output are known as Escape sequence character. 

The following is a list of six escape sequences.

\n Newline

\t Horizontal Tab

\v Vertical Tab

\b Backspace

\r Carriage Return

\\ Backslash

(i) #define CUBE(x)

(x * x * x)

main( ) {

printf(“%d”, CUBE(4+5));

}

(ii) int j = 5;

printf(“%d”, j = j == 6);

printf(“%d”, j = ++j == 6);

(iii)for (j = 0; j = 3; j++)

printf(“%d”, j);

(iv)main( )

{

static char a[ ] = “Test String”;

static char *b = “Test String”;

printf(“%d %d”, sizeof(a), sizeof(b));

}

(v) main( )

{

enum test

{RED, BLUE, GREEN}; enum test t = BLUE;

printf(“%d”, t); }

(vi) main( ) {

union U { int j; char c; float f;}

u; u.j = 10; u.c = ‘A’; u.f = 99.99;

printf(“u.j = %d u.c = %c u.f = %f”, u.j, u.c, u.f);

}

(i) Output is: 49 macro cube(x *x*x) is expanded into (4+5*4+5*4+5) which is evaluated as 4+20+20+5=49 due to priority of operators. So output is 49.

(ii) Output is: 0 0 Both the expressions are evaluated as 0 so the output is 0.

(iii) Output is: infinite loop There is an incorrect assignment, j=3 in test expression.

(iv) Output is:12 2, The printf is printing the size of char array a and char b, null char is included.

(v) Output is:1, The compiler automatically assigns integer digits beginning with 0 to all the enumeration constants so BLUE has value 1.

(vi) Output is: u.j=1311,u.c=’β’,u.f=99.989998 The first two outputs are erroneous output which is machine dependent. During accessing a union member, we should make sure that we are accessing the member whose value is currently stored otherwise we will get errors. 

Correct option- (A) fully parenthesised infix expression 

Alwars were the famous Tamil Poet Saints of Tamil Nadu and also called as Azhwars. They praised the Hindu Supreme God Vishnu and his Avatar Krishna with their own composed songs. The Alwars had the belief that Vaishnavism and Lord Vishnu were the supreme beings and look after the devotees with compassion.
