C programming

Define structure and nested structure. Write a program to find out whether the nth term of the Fibonacci series is a prime number or not. Read the value of n from the user and display the result in the main function. Uses a separate user-defined function to generate the nth Fibonacci term and to check whether that number is prime or not.

Explain the relation to array and pointer. Differentiate call by value and call by reference with a suitable program.

Differentiate between source code and object code. Create a structure named Book with members Book_Name, Price and Author_Name, then take input for 10 records of Book and print the name of authors having the price of book greater than 1000.

Describe the different types of I/O functions used in file handling with syntax.

Write a program to read P*Q matrix of integers and find the largest integer of each row and display it.

Write a program to calculate the factorial of a given number using recursion.

Write a program to check whether the entered word is pallindrome or not.

List different types of operators and explain any three of them.

Trace the output

#include

#include

void main(){

int i =0,k;

for(k=5;k>=0;k–){

i=i+k;

}

printf(“%d\t”,i);

getch();

}

Write a program to compute the sum of first 10 even numbers using function.

What is dynamic memory allocation? Explain with a suitable program.

Write a program to initialize an array of dimension 10 and sort the numbers within the array in ascending order.

What is the difference between exit(0) and exit(1)? Discuss the need of nested structue with an example. Write a program to find the value of xy without using POW code.

Why do we need a break and continue statement? Define formal argument and actual argument in function with examples. Identify and list the errors in the following code.

int main(){
int a,b,c
scanf(“%d%d%d, &a, &b, &c);
sum(a, b, c);
return -1;
}

void sum(int x, int y, int z){
int sum;
sum = a + b + c;
return sum;
}

Write a program to demonstrate the following menu-driven program. The user will provide an integer and alphabet for making choice and the corresponding task has to be performed according as follow:

• Find Odd or Even
• Find Positive or Negative
• Find the Factorial value
• Exit

The choice will be displayed until the user will give “D” as a choice.

How do you swap the values of two integers without using the third temporary variable? Justify with the example.

Write a program to find the sum of digits of a given integer using recursion.

Differentiate between constant and literals. Why do we need to define the type of data?

Write a program to find the second largest number in the given array of numbers.

Create a structure “Employee” having Name, Address, Salary, and Age as member functions. Display the name of the employee having aged between 40 and 50 are living in Kathmandu.

List any one advantage and disadvantage of the pointer. How do you pass pointers as function arguments?

Suppose a file named “Num.txt” contains a list of integers. Write a program to extract the prime numbers only from that file and write them on “Prime.txt” file.

What is the advantage of the union over structure? List any four-string library functions with the prototype.

Write short notes on

• Local, Global, and Static variables
• Conditional Operator

What do you mean by jump statement? Explain each jump statement with example. Write a program to check whether a number entered is prime or not.

Explain any three string functions. Write a program to check if two matrices are identical or act.

Define structure. Explain nested structure with example. Create a structure named book with name, author, and publisher as its members. Write a program using this structure to read data of 50 books and display name of those books published by “XYX” publisher.

Discuss structure of a C Program with suitable example.

What is variable? How is it different from constant? How do you write comments in c?

Explain formatted I/O functions in detail.

Write a program using your own function to find sum of two numbers

Write a program to print largest among three numbers entered by the user.

Explain dynamic memory allocation with example

Write a program that simply reads data from a file

Write a program to draw a line using graphics function.

Write short notes on:

• History of C
• Bitwise Operator

What do you mean by looping? Explain while loop with suitable example. Compare while loop with do-while loop. Write a program to find sum and average of first n natural numbers.

What is structure? How is it different from union? Create a structure named course with name, code, and credit_hour as its members. Write a program using this structure to read data of 5courses and display data of those curses with credit_hour greater than 3.

What is structure? How is it different from union? Create a structure named course with name, code, and credit_hour as its members. Write a program using this structure to read data of courses and display data of those curses with credit_hour greater than 3.

Explain flowchart with example. What are the benefits of using flowcharts?

What is data type? Why do we need it in programming? Explain any three basic data types with example.

What do you mean by unformatted I/O? Explain
