�

**Objectives: TOP**

�To make the student learn a programming language.

�To teach the student to write programs in C to solve the problems.

�To Introduce the student to simple linear data structures such as lists, stacks, queues.

Recommended Systems/Software Requirements:

�Intel based desktop PC

�ANSI C Compiler with Supporting Editors

**Week l.a)**Write a C program to find the sum of individual digits of a positive integer.b) A Fibonacci Sequence is defined as follows: the first and second terms in the sequence are 0 and 1.Subsequent terms are found by adding the preceding two terms in the sequence. Write a C program togenerate the first n terms of the sequence.c) Write a C program to generate all the prime numbers between 1 and n, where n is a value supplied by theuser.

**Week 2. a)**Write a C program to calculate the following Sum: Sum=1-x2/2! +x4/4!-x6/6!+x8/8!-x10/10! b) Write a C program toe find the roots of a quadratic equation.

**Week 3**

a) Write C programs that use both recursive and non-recursive functions i) To find the factorial of a given integer. ii) To find the GCD (greatest common divisor) of two given integers. iii) To solve Towers of Hanoi problem.

**Week 4a)**The total distance travelled by vehicle in t seconds is given by distance = ut+1/2at2 where u and a are the initial velocity (m/sec.) and acceleration (m/sec2). Write C program to find the distance travelled atregular intervals of time given the values of u and a . The program should provide the flexibility to the userto select his own time intervals and repeat the calculations for different values of u and a .b) Write a C program, which takes two integer operands and one operator from the user, performs theoperation and then prints the result. (Consider the operators +,-,*, /, % and use Switch Statement)

**Week 5a)**Write a C program to find both the largest and smallest number in a list of integers.b) Write a C program that uses functions to perform the following:

i) Addition of Two Matricesii) Multiplication of Two Matrices

**Week 6**

a) Write a C program that uses functions to perform the following operations: i) To insert a sub-string in to a given main string from a given position. ii) To delete n Characters from a given position in a given string.

b) Write a C program to determine if the given string is a palindrome or not

**Week 7a)**Write a C program that displays the position or index in the string S where the string T begins, or 1 if Sdoesn t contain T.b) Write a C program to count the lines, words and characters in a given text.

**Week 8a)**Write a C program to generate Pascal s triangle.

b) Write a C program to construct a pyramid of numbers.

**Week 9**

Write a C program to read in two numbers, x and n, and then compute the sum of this geometric progression: 1+x+x2+x3+& & & & .+xn For example: if n is 3 and x is 5, then the program computes 1+5+25+125. Print x, n, the sum Perform error checking. For example, the formula does not make sense for negative exponents if n is less than 0. Have your program print an error message if n<0, then go back and read in the next pair of numbers of without computing the sum. Are any values of x also illegal ? If so, test for them too.

**Week 10**

a) 2 s complement of a number is obtained by scanning it from right to left and complementing all the bits after the first appearance of a 1. Thus 2 s complement of 11100 is 00100. Write a C program to find the 2 s complement of a binary number.

b) Write a C program to convert a Roman numeral to its decimal equivalent.

**Week 11**

Write a C program that uses functions to perform the following operations: i) Reading a complex number ii) Writing a complex number iii) Addition of two complex numbers iv) Multiplication of two complex numbers

(Note: represent complex number using a structure.)

**Week 12a)**Write a C program which copies one file to another.b) Write a C program to reverse the first n characters in a file.(Note: The file name and n are specified on the command line.)

**Week 13a)**Write a C programme to display the contents of a file.b) Write a C programme to merge two files into a third file ( i.e., the contents of the first file followed by

those of the second are put in the third file)

**Week 14**

Write a C program that uses functions to perform the following operations on singly linked list.: i) Creation ii) Insertion iii) Deletion iv) Traversal

**Week 15**

Write C programs that implement stack (its operations) using i) Arrays ii) Pointers

**Week 16**

Write C programs that implement Queue (its operations) using i) Arrays ii) Pointers

**Week 17**

Write a C program that uses Stack operations to perform the following: i) Converting infix expression into postfix expression ii) Evaluating the postfix expression

**Week 18**

Write a C program that implements the following sorting methods to sort a given list of integers in ascending

order i) Bubble sort ii) Selection sort

**Week 19**

Write C programs that use both recursive and non recursive functions to perform the following searching operations for a Key value in a given list of integers : i) Linear search ii) Binary search

**Week 20**

Write C program that implements the following sorting method to sort a given list of integers in ascending order:

i) Quick sort

**Week 21**

Write C program that implement the following sorting method to sort a given list of integers in ascending order:

i) Merge sort

**Week 22**

Write C programs to implement the Lagrange interpolation and Newton-Gregory forward interpolation.

**Week 23**

Write C programs to implement the linear regression and polynomial regression algorithms.

**Week 24**

Write C programs to implement Trapezoidal and Simpson methods.
